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!

Sticky Stuff: 15 Ways Duct Tape Can Save The Day

Original Article by PartSelect Blog

Written by Alison Hudson

No matter what the seasons is, a trip in the backcountry requires a few essential items: food, shelter, and duct tape. For some people, the list could be whittled down to simply duct tape. Its adhesive capabilities and waterproof exterior make it one of the most dextrous tools you can carry; in a pinch, it can be used to build a shelter and create snares to catch food. Try turning a freeze-dried meal into a tent or vice versa! If you aren’t sold on the wonders of duct tape, here are fifteen reasons to bring a roll on your next wilderness expedition (and a few tips for how to keep your stash of tape organized and safe from the elements).

 

How to Pack It

On a backcountry trip, you won’t be happy carting around an entire roll of duct tape, replete with the inner cardboard roll: it’s heavy, it’s bulky, the cardboard will disintegrate when it gets wet, and the roll takes up an inordinate amount of space. Here are a few techniques for efficiently packing duct tape to bring on your next trip.

 

Flat Wrap

A little time consuming, but with a nice, compact final product. Simply start unrolling a little of the tape. When you have about 4 inches unspooled, fold the tape back on itself so you have two sides that are not sticky. Keep folding the tape on top of itself until you have the amount you need for your trip. Pack the duct tape in a ziplock bag to keep it from sticking to other things in your pack.

 

Spool

This is a common trick used by people who hike with trekking poles. Start by holding the trekking pole sideways so that it’s easier to work with the tape. Then wrap the duct tape around the trekking pole until you have the desired amount. If you don’t like a thick roll of tape, consider wrapping half on one pole and half on the other.

 

Half Spool

For little fixes, it’s nice to have a thin strip of duct tape, rather than the bulky width of the tape on the roll. To create a half spool, find something round, like a tent pole splint or a pencil. Using a sharp blade, slice the duct tape on the roll so that you have either two or three equal widths of tape; if you score all the way around the roll, it’s a lot easier to pull off. Start rolling one strip around the pencil until you have enough.

 

Mix it Up

Duct tape now comes in a variety of colors and patterns, all of which have the same strength and stickiness of the original silver tape. If you’re hunting, pick up some camo-colored tape (or hunter orange for making yourself visible). If you’re wrapping tape around trekking poles, having two different colors of tape can help differentiate the two poles. If you anticipate using the tape to mend clothing, tents, or other wearable items, black, blue, or dark green make more discreet patches than the bright silver. Neon shades work especially well for marking trails because they show up so much better than silver or dark colors.

Fix Things

The original purpose of duct tape was to make repairs. This is one of its best applications in the wilderness, where supplies are limited and multi-purpose items are priceless.

 

Fix Your Gear

Broken Ski

A broken ski can be a huge hindrance, especially if you’re far from your car. Duct tape can be used for an easy fix, whether it’s a nordic or downhill set up. Using a thin tree branch as a splint, tightly wrap duct tape around the stick and both pieces of broken ski.

 

Repair a Tent (pole)

A broken tent pole can be detrimental to an extended camping trip. Even if your tent came with a splint for a broken pole, duct tape is a lot easier to use. Place the broken ends side by side, so they overlap, and wrap them tightly with tape.

 

Inflatable Mattress

Nothing is quite as pernicious as a leaky inflatable mattress. In a pinch, a circular duct tape patch will keep the air from escaping while you sleep through the night. Be sure to clean the area around the patch before placing the tape to make a better seal.

 

Repair Clothes

Rips, tears, shredded cuffs, all of these can easily be fixed with some masterfully placed duct tape. For rips, use a round piece of tape because the lack of corners makes it more likely to stay in place. For cuffs, fold a piece over the edge and press it smooth.

 

Repair Sunglasses

Broken ear piece, loose lenses, snapped nose bridge: these are just some of the ways in which sunglasses can break at the more inopportune time. Duct tape can be used to fix all of these problems, whether it means wrapping the nose bridge in a thin strip, wrapping the ear piece with a wide piece, or carefully outlining the lens with tape to keep it from falling out.

Fix Yourself

Band Aid

It may not have the same padding, but duct tape will keep a wound dry while keeping dirt and other detritus from causing an infection.

 

Ankle Wrap

Though not as flexible as athletic tape, duct tape will make a useable ankle wrap in a pinch. Wrap the tape with the sticky side out to prevent tearing skin away when the wrap is removed.

 

Prevent Snow Blindness

Forgot your glacier glasses in Base Camp? Duct tape can be used to make improvised sunglasses that will help prevent snow blindness and other eye injuries from bright sun on snow or water. Simply cut a width of duct tape (or two) that will extend across your face and make two very narrow slits where your eyes line up with the tape.

 

Tick-proof

In deep weeds or grasses where ticks are prevalent, it’s vital to seal all entrances to bare skin. Wrap duct tape around the bottom of your pants and tops of your socks to keep ticks from slipping through while you walk.

 

Cover Bug Bites

Some bug bites react well to being covered with tape, especially chigger bites. If you’re getting plagued by bug bites, use duct tape to cover the itchy bites and prevent worse damage.

Prevent Things from Breaking

Duct tape is perfect for preemptive use on gear that could get damaged.

 

Pants Cuff Care

How many pairs of hiking pants or rain pants have you seen with blown out cuffs? It’s easy to ruin a pair of expensive pants by walking on the cuff. To prevent fraying, use a piece of duct tape to reinforce the hem. This is especially useful for rain pants, which are expensive to replace.

 

Waterproof Map Case

Duct tape is an inexpensive way to waterproof papers and other items that need to be protected from the rain. To make a map case, start by cutting two pieces of cardboard to match the size of your map or other papers. Once you’re created the template, cover the cardboard with stripe of duct tape. Be sure to overlap the edges of each piece to make it extra waterproof.

 

Dry Bag For Electronics

Using the same process described above, you can easily create a waterproof case for your electronics (everything from a smart phone to a satellite phone).

 

Hide-a-Key

It’s the last day of your wilderness trip and you’re back at the trail head exploding your back in search of the car key. Next time, use a piece of duct tape to secure your key under the car. That way you don’t have to worry about losing it in the woods or a lake.

 

Mark a Trail

Bright strips of duct tape can be used to flag a trail through the woods so that you or others can follow the path without getting lost.

 

A roll of duct tape and some creativity will go a long way toward relieving a stressful situation in the wilderness. Always pack more tape than you think you’ll need and don’t be afraid to experiment with bold ideas; when duct tape first came out on the market it was used on weapons, military vehicles, and boots. There is no situation too sticky for some duct tape.
