The affects of the Black Mamba's bite

   
       The bite of a Black Mamba is feared by anyone that lives in their habitat. It has the ability to strike several times delivering enough poison to kill 12 men with every bite. It is a feared predator hunting and protecting itself with it's bite. The poison causes many different affects once it is in your body. The neurotoxin in it's poison causes the nervous system to fail. You will start to loose your vision and become nausous. Within ten minutes of the bite you can go into cardiac or respiratory arrest.

     Mamba venom is made up dendrotoxins, fasciculins, and calciseptine. The venom is a light weight protein which allows it to spread very quickly. The dendrotoxins affect the exogenous process of muscle contraction by attacking the sodium potassium pump. The venom is very specific and super deadly.

Cystic Fibrosis

Cystic Fibrosis is a disease that is a hereditary disease. Signs and Symptoms of this disease include:
O: very salty-tasting skin;
O: persistent coughing, at times with phlegm;
O: frequent lung infections;
O: wheezing or shortness of breath;
O: poor growth/weight gain in spite of a good appetite; and
frequent greasy, bulky stools or difficulty in bowel movements.

About 1,000 new cases of cystic fibrosis are diagnosed each year.
More than 70% of patients are diagnosed by age two.
More than 45% of the Cystic Fibrosis patients are age 18 or older.
Doctors predict that a patient with Cystic Fibrosis will live to about their mid 30's.

It is diagnosed with several different types of anti-biotics that can be used.

Clearing your airway, imported devices, and nutrition and eating right. With these therapies you will slow the mucus build up, but there is no permanent way to cure this disease.

To test for Cystic Fibrosis a doctor will perform a sweat test if signs show the disease. It is a painless test that checks for a high concentration of salt. With a high concentration you might have Cystic Fibrosis. Also you can do a new born screening which will benefit the baby and help add years onto it's life. And a third was is a Carrier Test. More than 10 million Americans carry this disease, but don't have the symptoms. This disease is passed only through inheritance of one copy of the defective gene.
25% (1 in 4) the child will have CF;
50% (1 in 2) the child will carry the CF gene but not have CF; and
25% (1 in 4) the child will not carry the gene and not have CF

Structure and Importance of the Membrane

In this blog I decided to do a prezi. It is about the structure and importance of the molecule.

Collagens

              About one quarter of all of the protein in your body is collagen. Collagen is a major structural protein, forming molecular cables that strengthen the tendons and large resilient sheets that support the skin and internal organs. Bones and teeth are made by adding mineral crystals to collagen. Collagen provides structure to our bodies, protecting and supporting the softer tissues and connecting them with the skeleton. But, even with its critical function in the body, collagen is a pretty simple protein. Collagen is a type of protein that is wound tightly together forming a triple helix bond. Each structure is over 1400 Amino acids.
             Vitamin C helps to stabilize the Collagen. It helps modify the regular promise amino acid by assist in the addition of oxygen. Without enough Vitamin C in your body you won't be able to make new Collagen which will cause scurvy. Scurvy causes you to loose teeth and bruise easily.
             In a Collagen their quaternary structure is very easy to see. To determine this you can look and see how many cables are joined together to form the collagen. A collagen has three cables braided together to form a Collagen.
           The main symptom of the genetic disease Osteogenesis Imperfecta is when you have weak bones . People with OI also often have muscle weakness, hearing loss, fatigue, joint laxity, curved bones, scoliosis, blue sclerae, dentinogenesis imperfecta (brittle teeth), and short stature. Restrictive pulmonary disease occurs in more severely affected people. This decease makes you more vulnerable to fractures and other injuries occurring with the bones. Type I Osteogenesis is the most common form. This is also the most mild form. It is caused by a defect in the parents genes which the child has a possibility of inheriting it.
            Collagens play a huge role in your bones. It is important to have a collagen for your bones that way they can get vitamin c. Collagen strengthens your bones and helps other bodily functions. It also keeps your muscles strong too. Collagen is a little molecule that makes a big difference in your body.
           
            

Magic of Molecules

             What if a random guy came up and said for a million dollars what is a macromolecule? Would you be able to win it? Well the answer to the is that a macromolecule is about everything biology. It is a protein, carbohydrate, lipids, and nucleic acid. They are involved in all structures and processes of organisms. When dealing with macromolecules you are able to determine whether it is a monomer or a polymer. A monomer is part of the macromolecules. It takes two or more groups of monomers to become a polymer. A polymer is another name for macromolecules which is a group of monomers. Macromolecules undergo reactions that include Dehydration synthesis and Hydrolysis Reaction. To take apart a monomer, water is taken away which is Deydration synthesis. To break down a polymer you do the complete opposite. All you have to do is add water which is called Hydrolysis Reaction. The bond between two monomers is called a Hydrogen Bond. This happens when a hydrogen atom and oxygen atom bond together. The enzyme that joins monomers together is called a Polymerase enzyme. To join sugar monomers together to build a polysaccharide by dragging them into the right position. Molecules not used in building a carbohydrate includes fatty acid, amino acids, and Necleotides. Sugar is stored as glycogen so that the human body is able to store the glycogen as energy for future use. It helps you perform longer and keeps your body going before it has to result to fat. Plants are used as Carbs, vitamins, minerals, and non digestible fibers. Fiber is used to help flush your valves. When you fart you really are putting out undigested proteins. With a low carb diet you are lacking stored energy and is nutritionally unhealthy. Now talking about your teeth. When sugar gets on your teeth everyone knows it can give you a cavity. A cavity is formed when the bacteria on your teeth is combined with a carbs in the sugar. This reaction creates an acid which then slowly eats away at the enamel on your tooth.

The Amazing Molecule

                      Water is only made up of three atoms that when bonded become one of the most important necessities of life. Our bodies are made up of about 70% water. It is a cohesive liquid which means that the molecules hold together using a hydrogen bond and stick to other water molecules. It also shows that water has a high surface tension. During our experiment we put drops of water on a penny. The water kept building up until the molecules couldn't fight gravity any longer. Another example of the hydrogen bond is when you start to boil water. When it starts to steam the water molecules are breaking off of each other with a lot a energy. Water is also adhesive with many things like string, paper, and tubulars of trees. As an experiment to explain this concept we took two beakers and filled one up with water and left the other empty. Our objective was to get the empty beaker full of water by having it travel along a string. We were able to a piece of wet string that was 16 feet 6 inches long. How we did it is we knew the water would bond together and travel down the string. This experiment showed both these properties of water. Water is a adhesive and cohesive molecule.

A controlled experiment

          

             In this experiment on the computer we tested factors that could cause differences in how corn grows. It was important to do a controlled experiment first. This let us know how we could compare the other experiments. When I added the independent variable which was the ECB, the corn didn't grow as healthy and lacked in growth. I also found that the more I added the less the corn was able to produce. The production was the dependent.

           In labs there are many different ways you can conduct them. With plant/animal you can set up an experiment and watch and record your data. You can set up many different trials to find out what all affects the dependent variable. This is different when you start to conduct experiments with human trials. There are two different ways to do this; Interventional or Observational. Interventional is when the test subjects are given a treatment and then research is done on them to decide if it worked or not. Observational is when the test subjects are observed and outcomes are measured.
         Sometimes doctors will give you something called a placebo, this is a mind trick with the patient. The patient thinks its a normal drug but it really does nothing. A double-blind trial is when the doctor also doen't know that he just gave the patient a placebo.
