5 Reasons Why Biology Homework Is Essential For Your Survivability

As a student, you need to view homework as more than just a way to improve your grades in school. Learning should not be centered around the four walls of a classroom. When you have the right attitude toward learning, and toward your biology homework, you will learn skills that are essential for survival in different situations. You see, biology as a science studies life forms. It dwells on everything regarding life from the single cell organisms to multi-cell organisms. Freelance writers who write about biology can testify to this fact that knowledge of biology is key to survival.

5 Reasons Why Interest In Biology Can Save Your Life

1. In Case You Get Frostbite

Frostbite can happen when you stay in cold regions for an extended period. Whether you’re there by choice or by force, knowledge of biology can help you survive. While a mild case of frostbite will not cause any lasting damage, a more serious case can lead to a number of severe symptoms. Some of these include blistering, loss of feeling, cold sensitive, and hypothermia all of which can lead to death. The worst mistake you can make at a time like this is using friction to warm the part of your body that is affected. This can damage your tissue.

2. In Case Of A Heart Attack

While heart attacks are more likely to happen to people who are more advanced in age, youths still have a slight risk of having a heart attack. When the body can no longer pump blood to the heart efficiently, the heart muscles suffer a deficit in oxygen and die. From a biology textbook or articles written by freelance writers, you can learn the symptoms of a heart attack and seek out professional help. Taking an aspirin tablet as soon as you notice the symptoms can reduce the risk of clot formation. If you’re not the one having the heart attack and the patient is not responding, attempt cardiopulmonary resuscitation with your hands.

3. In Case You Suffer Burns

There are several circumstances that can lead to burns. Whatever the case may be, knowing about the human body will help you get or provide instant relief before experts get there. Most people think the best way to relieve a burn is with ice. This is only going to damage the burnt skin more. The best thing to do in such a situation is to use a sterile dressing to cover the affected skin and wait for the medical team to arrive.

4. In Case Of Convulsions

If someone around you suffers a convulsion, you can quickly check the internet for an article about how to provide first aid. There are many articles by freelance writers about this emergency. A convulsion is also called a seizure and it’s a situation where a person suffers rhythmic movements of the muscles that cannot be controlled. It happens when the brain receives abnormal electrical impulses. While these seizures can stop without any first aid, you can help the victim by assisting them to lay down in a comfortable position. It’s common to see people put objects in their mouths but this should be avoided. Just remove harmful objects from the environment and wait for a medical professional.

5. In Case Of A Traumatic Head Injury

You can suffer a traumatic head injury when you hit your head hard. If you don’t get medical attention as soon as it happens, you will be at risk of brain damage. The first thing to do would be to call for professional help. If you’re not the one who got injured, you can assist the victim by checking if their airways are blocked. If the person is not conscious, perform CPR.

There are many other ways to care for yourself or someone else during a medical emergency. Learning about how the human body works during biology lectures or from freelance writers will teach you more survival techniques in cases of emergency.

How to Sharpen Serrated Edge Knives-Serrated Knife Sharpening

Today I thought I would talk about a little problem that many folks that carry and/or use knives in their homes seem to have all over the country. That little problem is serrated knives. We all own them in one form or another like a serrated survival pocket knife or serrated bread knife or even a serrated carving knife. There is an issue that arises for many people that own serrated knives. That issue is how to properly sharpen a serrated knife? The question of the ages for the modern knife owner. In this post, I am going to address this issue and when I am done with it you will know how to sharpen your serrated knives.

How to Sharpen Serrated Edge Knives

For the most part, your serrated kitchen or pocket knife will stay sharp longer than your straight edge pocket or kitchen knives will and they will even cut when the serrations are getting dull. As the scallops and teeth of a serrated knife get dull the quality of the cuts that you once got will slowly degrade into tearing, pulling and shredding of the item that you are cutting. When this tearing/shredding effect starts to happen then it is time to sharpen your knives.

For many people the chore of sharpening knives is time-consuming and for many, it is a daunting chore. The fact of the matter is that sharpening serrated knives for many is more problematic than sharpening standard straight edges. Proper care and maintenance of serrated knives will keep those scallops cutting cleanly for a long time. Have no doubt though; these serrated knives do need a greater level of experience to sharpen properly. Another thing to consider is that serrated knife blades take longer to sharpen than their plain edged counterparts.

As I said earlier serrated knives can and do stay sharper longer than plain edged knives and because of this it will take longer for a serrated blade to become dull, and this is even true for combination bladed pocket and kitchen knives. The “teeth” of a serrated blade “bite” or start the cutting process first and then the scallops of the blade follow through to complete the cut. The “teeth” take most of the cutting pressure and the scallops take the least amount of cutting pressure. Because the scallops take the least amount of cutting pressure they stay sharper longer.

Now let’s talk about how to sharpen your serrated knives. In order to do this, you will need to obtain the correct type of sharpener designed for sharpening these types of blades. There are many on the market made by many manufacturers that are specific to the chore. Some are good, and in my humble opinion, some are just plain old bad. Some of the types of serrated knife sharpeners are the “draw through” type. (I personally do not care for “draw” or “pull” through sharpeners)Then there are the sharpening rods that come both in standard and tapered versions and made of different materials from carbide to diamond coated. There are specialized serrated sharpening stones that are textured to accept the scallops of serrated knives. Many of the sharpening rods or sticks come in a triangular shape to work on the scallops between the teeth of the knife. The “rat tail” type of file or sharpener is tapered in order to naturally fit the diameter of the scallops of the blade. The one thing to keep in mind when wanting to sharpen serrated knives is that as with sharpening plain edges you will have to take the same considerations with serrated knife edges and that means that you will need to choose the correct sharpener and what materials you want that sharpener to be made of.

Many of the sharpeners that you would use to sharpen a serrated knife can be used to sharpen plain edged knives as well and you can get pocket-sized sharpeners for serrated knives and combo edged knives to carry with you for daily honing and sharpening of your daily carry knife.

When it is time to sharpen your knife whether it is a plain edge or a serrated edge one of the things to keep in mind is the angle that you will use to sharpen your knife. It does not make any difference what type of sharpener you use, keep the angle in mind. Most of the time when sharpening combo edged blades the serrated portion of the blade in the majority of cases will be of the same angle as the plain edged section of the blade. This means that when sharpening the serrated section of a combo edge it should be kept at the same angle as the plain edge section of the blade as well. Now there are many sharpeners out there that are referred to as “guided” sharpeners like the Lansky Sharpening Systems. This type of system will maintain the proper edge angle as you sharpen your knives and you can get stones or diamonds that are triangular in shape to sharpen your serrations at the correct angle with the Lansky System too!

Many people that I have met and many people that call themselves “professional knife sharpeners” for a living have sharpened serrated knives by either drawing the back/flat side of the knife across a bench stone, and in many cases I have seen them sharpened by drawing the back/flat side of the serrated knife across a sanding belt. This is not the correct way to sharpen this kind of knife. I order to sharpen the scalloped part of a serrated knife you can use the serrated sharpening stone or diamond from something like the Lansky System and work it into the scallops in a perpendicular movement to the cutting edge one scallop at a time. You can also do the same thing using one of the many diamond or ceramic files or tapered “rat tail” files and move them in the same perpendicular fashion to the cutting edge of the scallops.

Remember, you have to take your time and sharpen one scallop and one tooth at a time before moving to the next one. When you are done you should be able to feel a “burr” on the flat side of the knife. Many will tell you to lightly grind that burr off. I do not do this and I tell others not to do this. I have a small piece of 2X4 wood and I then lightly draw the serrated blade across a corner of the 2X4 to remove the burr this is also the way many people who sharpen Japanese kitchen knives do it as well. You can also take a hand held ceramic rod and start at the top of the rod and work your way down to remove the burr and polish the flat of the blade. When you “grind” you are removing metal and when you use a ceramic rod you are taking much, much less metal from the blade. I do it this way for the longevity of the blade.

Here is another way to sharpen a serrated knife really quick that I use all the time. Take corrugated sharpening steel and then take your serrated knife and start at the bottom of the steel at the handguard and take the very tip of the serrated knife and stroke the blade across and up the steel holding the blade at your chosen angle. Don’t just put the flat of the blade flat on the steel. Put the flat to the steel flat and then raise it up to your desired angle. If you know what 20 degrees looks like when sharpening on a flat stone then you should know what 20 degrees look like against the sharpening steel. Then after 10, 20, 30 reverse strokes up the steel the burr will be raised on the flat of the blade and I lop it off on the 2X4 and then a few strokes on the ceramic rod to polish the flat and I am good to go!

101 Uses for Paracord [infographic]

There’s a good reason why you don’t bring a lot of things with you when you go on an outdoor adventure. You may need a pillow for a more comfortable rest at night inside your tent, or a rope ladder to climb some treacherous terrains. But you don’t bring all of what you think you might need when camping or trekking or whatever you do in an adventure. If you did, you would be carrying your whole house with you.

 

This is where a modest piece of equipment comes in. A paracord looks like it won’t be much, but it can actually do so much. A paracord, which means a parachute cord, is basically a lifesaver. You need a shoelace? Use a paracord. Your leather watch strap ripped? A paracord will hold it together. You suddenly need to rappel? Paracord can be your lifeline. Aside from the obvious uses—such as tying an object to something or using it as a rope—there are a lot more that you can do with a paracord. You don’t have to be trekking in the countryside or camping in the wild to have a use for it. You can find that even in an urban setting, a paracord can be crucial to you.

 

Learn how to use a paracord in so many different ways in the infographic below.

Airbed vs Sleeping Bag – Which is Better for Outdoor Survival?

Preppers who are just starting to learn about survival in the outdoors tend to compare the experience with camping, but besides the fact that you’ll have to live and sleep under the clear sky, the resemblance ends here.

Unlike camping, where you eat the food you brought from home, in a survival scenario you’ll be forced to hunt your own dinner. This is why, when you prepare the BOB, you must consider the type of hunting equipment to include.

You’ll also have to rationalize food supplies, learn how to use the environment in your favor, and last but not least, manage to be comfortable enough to catch some Zzz’s. When I describe the process this way, most new preppers get a bit anxious. And, while they’re quite OK with most of the processes, I get a lot of questions about sleeping outdoors and the equipment one should pack.

How to Sleep Outdoors and Be Comfortable

When you don’t have a car to serve as a temporary home, or even a tent to keep you warm during the night, how do you get by?

Well, first I want everyone to know that sleep is crucial in an SHTF scenario. If you’re sleep deprived, your mind will get fuzzy affect fast decision making, your hands may tremble while you’re trying to hunt, and you may lose focus during a life and death situation.

Now that everyone is up to speed, I must highlight the fact that the quality of sleep is just as important. This is why you should always try to improvise a bed that provides some cushioning and protects your body from humidity and low temperatures.

For this, the best equipment to have in your BOB is a sleeping bag and an insulating layer. For the insulating layer, you can use either an air bed or a self-inflating sleeping pad, but in my opinion, air beds are a bit more advantageous – learn more about it here.

But, if you’re forced to choose between the two, which one is more important?

Air Bed vs. Sleeping Bag

When you decide which elements go in your BOB, it’s important to understand their use on the long-term. So, I am not just going to tell you that the sleeping bag is more necessary; I am going to show it to you by comparing the two.

The sleeping bag is designed to cover your entire body and fit around you like a protective cover. I recommend getting a mummy type, so you’ll have protection around the head as well. Sleeping bags come with various levels of insulation but for an SHTF scenario, I recommend one that can be adjusted for all seasons. This type of bag has some inner lining that can be removed when it’s too hot outside, so you won’t sweat.

The main purpose of a sleeping bag is to keep you warm, but it won’t provide insulation from the ground or cushion the feel of a hard surface.

On the other hand, an air bed will do just that: provide insulation from the cold ground and cradle your body while supporting the spine. However, it doesn’t wrap around you, so it won’t provide protection from the cold night air or the humidity.

As you can see, if you have the possibility, it’s ideal to combine the two. But, when you can only take one, the sleeping bag wins. It’s lighter, more compact, and can be used in all sorts of situations. After all, you can always create a bed of leaves or tree branches – it won’t be as comfortable as an air bed, but it will provide insulation.

Sounds Fishy: An Often Overlooked Bug-Out Bag Item That I Always Add

I’m always intrigued by what people argue about when trying to decide what to put in their bug out bag or survival kit. You know…. fire starters, water filters, food rations, I need not say more. We all picture survival scenarios that we try to be prepared for. Maybe one of those is being stranded in the woods or lost near a stream or lake.

So here is a question…..Do you have any actual fishing lures and line in your kit? I’m not talking about a bit of string, a few hooks and a sinker. I’m talking about maybe a small 150 yd spool of super high tech fishing line. Maybe you have paracord in your kit but think you have nothing but time to strip one of the 8 strands out of it and use it for lashing or fishing line. Why waste your time and precious resources? The latest technology can give you the diameter of old 4 lb test with the strength of 40 lb test using super braids made out of exotic fabric like trademarked “Spectra” lines. Snares, bed and shelter lashing, trip lines, temporary sutures, and yes fishing, the possibilities are endless and ready to use.

So you have some compact line, what kind of lures could you carry for let’s say a salt, fresh or fly fishing situation? Opinions are close but vary on the top 10 lures in the world for these types of fishing. Most would agree on our sample of a short list of some of the best lures ever invented because all and many more are time tested and proven fish catchers. Do your own research if you wish but consider the possibility of including one or two lures from each category to your well thought out survival kit.

Here’s a list of just a few lures to save you some time…..

Fresh water:

Heddon Torpedo, Red Devil or Daredevil Spoon, Rapala Floating Minnow, Panther Martin, Hula Popper, Mepps Aglia Spinner, and of course the famous versions of the rubber worm!

Salt Water:

Diamond Jig, Gold spoon, artificial shrimp or DOA shrimp, Mirrolure twitch baits, Bucktail jigs and Johnsons Silver Minnow

Fly fishing manufactured lures:

Hares Ear Nymph, Adams Dry Fly- which some consider the most effective, Woolly Bugger, and one of the new modern favorites…The green “mop fly” (That’s’ right, a fantastic lure made from the tiny microfiber fingers in a floor mop. Talk about survival…make your own!  It resembles the parachute inch worm which fall from trees and the trout and other fish go nuts.)

We hope this article gets you thinking of the few extra inches of space you could add to your survival kit and of course many arguments can be made of all the amazing lures we haven’t even begun to mention. That is the real point of the article…just to get you thinking and preparing!

Guerilla Gardening: Why We Think It’s A Good Idea To Plant Some Preps Along Your Bug-out Routes

Guerilla Gardening is not done by gorillas.  In fact it is usually done by little old ladies who sneak into people’s yards when no one is home.  At least that’s what I do.
Plant fruits and vegatables along your bugout routes

My first act of gorilla gardening was for my friend Joe.  He’d worked for many years on building a home whenever he had money available and help from friends.  The place was a cluttered construction site for a long time.  But as the building was nearly completed, and the construction debris cleared away, there was room in a sunny spot for a small garden.  I knew Joe wanted to grow some of his own food and where he intended to put a garden so when he left town for a week, I made my move.

I collected some discarded 4×4’s and some left over fencing and piled them into my station wagon along with some garden starts and headed over to Joe’s.  It’s a lovely place at the end of a dirt road.  I got to work with my digging fork and turned sod, weeded and formed beds.  I dug holes and erected the posts and fencing.  Then I planted the seeds and starts, salad greens, squash, peas and beans to climb the fence and a bed for perennials like rhubarb, herbs and raspberries.  I watered it all from the rain barrel.  When Joe came home and found it he was delighted.  Since then his garden has expanded to 5 times the size of the original.

I live on a small lot in town.  The previous owner traveled often so his landscaping was concrete and grass.  Now after 5 years, there’s a native plant garden on the shady side of the house with vine maple and crabapple trees, salal, Oregon grape, red flowering currant, columbine and wild ginger.  In the sunniest part of the yard, right up against the sidewalk, I have my espaliered fruit trees with 10 different kinds of fruit grafted on to 4 trees.  There are 2 blueberry bushes and strawberry plants.  In the beds there are potatoes, squash, peas, salad greens, broccoli, cauliflower and winter greens.  A stately rhubarb fills out one corner and cosmos bloom by the fence.  What a delight to grow my own produce.  I planted greens last August to winter over so I’m eating chard, collards, kale and beets year round. The chard with their red and yellow stems brighten up the flower beds.

Gardening on a small lot

It took a while for me to figure out what grows best here in the Northwest and in my yard.  Then I had to get used to eating what I grow.  But now I’m totally addicted.  I take some with me when I travel.

This spring my elderly neighbor said she wasn’t going to garden this year.  My ears perked up.  I asked, and she said to “Garden as if it was your own.”  That garden has been under cultivation for decades so mostly what I’m doing is weeding and uncovering the volunteers.  There’s lettuce, chard and garlic in abundance.  I added a few squash and beans and covered them with a floating row cover to keep the deer and squirrels at bay.

Another friend is moving from Whidbey where he’s lived for thirty years.  He has a well-established landscape.  I’ve been weeding with him there getting his house ready to sell and hearing about his projects restoring an old house in Port Townsend where he’s planning to move.  Last week while in Port Townsend, I put a couple of big pots on his porch, filled them with potting soil and added salad starts and a couple of squash.  A friend 2 doors down said she’d keep them watered. My friend was touched to find them the next day.  I love guerrilla gardening.
