RESPIRATION

Respiration is another way of saying breathing.Cellular respiration is a method that used to convert food into energy.In order to do this the cells need oxygen. Some cells use anaerobic respiration which basically means it doesn't need oxygen. An example would be when someone exercises they build up lactic acid in muscles. Respiration affects the body everyday whether we notice it or not.

Enzyme Lab

An enzyme is something that speeds up a chemical reaction. When we did the activity in class, we first had the enzymes reacting normally. When the inhibitors (things that are added to slow reaction down) were added, the process did slow down because they looked exactly like the enzymes. Then the enzymes don't work the way they are suppose to. They are controlled by temperature as well as the PH level. When the enzymes didn't know which one to choose, the rate of capturing slowed down. The activity is how we showed the relation.

Metabolism

A way for our bodies to get energy is the main concept of metabolism. It changes the food into nutrients that your body can use for energy. That is what keeps our cells working properly. Kids Health says "it is a process that begins even before were born and doesn't end until you die." But it doesn't just work in humans. It works in all living organisms. The chemicals break down the sugar and turn it into energy. Some people's metabolism is fast and others is slow. This just means that the body breaks down and uses the energy faster than others. If someone gets hungry faster than others than that means there body had already broken down their food. Energy that is not used is stored as fat and that slows down your metabolism. Energy it makes the world go round.

How PH, Temperature, and number of drops



  1. Graph 1 are Ph effects. The amount of pressure changes according to the level of acid in the beaker. The higher level of acid there was the more pressure there was. The level ten ph has the lowers pressure increase.
  2. Graph 2 is the number of drops of yeast that were added to the peroxide. The graph shows that the more drops that were added, the more pressure was present.
  3. Graph 3 is how temperature effects the pressure. With warm water, the beaker plug popped because the pressure was too great to hold it. The cold popped as well but it took a little longer that than the warm. The room temperature was a steady increase and the hot did not show much change in the pressure at all.
Even though we only look at these three effects separately, it is possible to make a combination of them to see which combination provides the best results to make it pop faster. It makes me wonder how fast it would pop if the peroxide was warm, had thirty drops, and contained a low ph acid.

Carbon Monoxide The Silent Killer

http://www.ncpoisoncenter.org/body.cfm?id=114

Carbon Monoxide is a gas that is created when you burn things that have carbon in them. You can't smell it and its colorless. When someone breaths it in they tend to come down with something that is similar to the  flu. The stuff that you breath in, oxygen, is stopped from reaching your brain and your heart. With transportation of oxygen in your body shutting down, you body can go into a coma and someone that has Carbon Monoxide poisoning could possibly die if exposed to it long enough.
So how to you get Carbon Monoxide poisoning? Not like you would ever want it. But doing things like using a gas oven to heat your home, burning charcoal, breathing in a space that doesn't have proper ventilation, or ignoring the symptoms of felling like your going to throw up, headaches or feeling dizzy.

If someone ever acquires carbon monoxide poisoning then the best treatment would be oxygen therapy but even then if you breath too much in, the damage done could be un-reverseable.

New Species Found in Yosemite National Park

This arachnid has been classified as a pseudoscorpion. So its has parts are half scorpion and spider. But instead of its venom being located in a scorpion stinger which it doesn't have, it is located in its claws.  The arachnid is blind, located in caves of granite and limestone filled caves, and extremely small. It could fit on the tip of your finger. They only use their venom for killing their prey.

Fluid Mosaic Model


Our poster describes a fluid mosaic model. The phospholipids are the circle things with the tails. The heads are the phospho part and the tails are fatty acid. Within the model are the glycoprotein and the transmembrane protein which transports things to the membrane. It is also polar.

PH Lab Revised

PH levels

The purpose of antacids are to reduce or neutralize an acid. The Ph system helps measure that. It measures the amount of alkaline or acidity a solution has. The more acidity something has, the closer to an acid it is. The more alkaline something has, the closer it is to a base. 7 on the Ph scale is neutral, neither nor. Its pretty self explanatory that a bad balance of acids can be bad.  With a 1 being an acid and a 10 being a basic, you can determine which antacids are the most effective when trying to settle your body. In the experiment we used Tums and Rholaids, regular and extra strength. All but one ended up with the same Ph level of six. The extra strengh Rholaids didn't have as much effectiveness as the rest with a five. This concludes that it doesn't matter which one you use because they both counteract with the acids the same. With other antacids the results may be different.

Healthy isn't in my Vocabulary except for now because I'm using it but other than this it isn't !

http://ezinearticles.com/?Carbohydrates-Food-Chart---An-Essential-to-a-Healthy-Lifestyle&id=4955531

I read an article about carbohydrates being an important part of your diet. The article was very specific about consulting a food chart in order to keep a healthy balance. Foods that we normally eat are included in the food chart. Starch, sugar, and carbohydrates numbers give you an idea of how much you are taking in. Pretty much any food you eat has carbohydrates that store energy to use later. Simple and Complex carbohydrates are good for you but the health people say that complex are better because the carbs that are not used don't go straight to fat like the simple carbs do.

So I took the liberty to look at my own carbohydrates chart based on my normal diet.
For breakfast I had two cups of hot chocolate. I drank about 20 grams of chocolate. This is an estimate of course. Then for lunch I ate 154 grams because I had pizza and 100 grams for the apple I ate. Right after that I downed a sugar cookie that was 20 grams. Then I had a hamburger for dinner grams are as following...
Cheese- 25
ketchup- 20g
meat- 170g
bread- 25g

The total grams of carbohydrates I ate for one day was around 460(g)
So healthy isn't in my diet but I sure do have a lot of energy stored up.

Clinical Trials- The Venom of the Beast

Alacramyn is a drug that is suppose to be used to reduce effects of scorpion venom. Since double-blind means that no one knows which patients got the drug then none of the patients or doctors knew who got the Alacramyn and who got the placebo, a type of pill or something that is another way of helping a patient.  The purpose of the treatment is to examine the drug in a neutral way. Even though the drug people are a mystery, the experiment is still controlled. With the scorpion venom, there had to be no trace of venom left for the clinical trial to be complete. Once the trial was complete, the Alacramyn patients blood decreased. The venom in the placebo patients still had to continue being sedated for a a little longer and had higher levels of it. So the drug was successful in its purpose and if you're ever stung by a scorpion, get the Alacramyn!
