Polymer A polymer is a substance that is made up of lots of smaller molecules (the smallest part of an element) that form together to make bigger molecules. A polymer can be natural or synthetic. A natural polymer already exists while humans make synthetic polymer.
Macromolecule A macromolecule is a very big molecule that is made up of many atoms. An example of what could be a macromolecule is a polymer or a even a protein.
Enzyme An enzyme is a protein that acts like a catalyst, which speeds up chemical reactions. The difference between a catalyst and an enzyme would be that an enzyme increases the rate of chemical reactions in living things. An enzyme, like a catalyst, converts the reactants into products of a chemical reaction.
Protein A protein is a substance made from amino acids. Amino acids are simple organic compounds that are an important part of living things. Proteins in the body are key in order for chemical processes in the body to take place. The main function of protein is to fight infection, heal wounds as well as build muscle.
Fiber

Fiber is described as being very thin, much like thread.
Fibrin The definition of fibrin is that it is a protein found in the blood that cannot be dissolved. It is a part of the clotting process in the blood where it forms a network of that is interlacing.
Factor XIII Factor XIII is involved in the body’s natural process of clotting the blood. Factor XIII crosslinks the fibrin in the blood in order to form the clot.
Femoral artery The femoral artery is the most significant artery that supplies blood to the leg. The femoral artery is situated in the thigh. An artery is a part of the circulatory system that links to the heart.
Haemorrhaging The act of having a haemorrhage. A haemorrhage is the uncontrolled release of
Enzymes are a biological catalyst, which controls a cellular reaction, they are proteins that act as a catalyst. A catalyst is a substance that speeds up a reaction but does not get used up. It works by reducing the Activation Energy, which is the minimum energy needed for a reaction to happen. A catalyst can make a reaction occur even if it would not happen other wise. Enzymes only affect the speed at which a product is formed, not how much is produced.
Background information:. Enzyme Enzymes are protein molecules that act as the biological catalysts. A Catalyst is a molecule which can speed up chemical reactions but remains unchanged at the end of the reaction. Enzymes catalyze most of the metabolic reactions that take place within a living organism. They speed up the metabolic reactions by lowering the amount of energy.
Elastic fibres enable the wall to stretch as blood surge through at high pressure. Tunica externa is the outer layer of connective tissues containing elastic and collagen fibres. It provides support for the blood vessel and attaches it to whatever other tissue it runs through. Artery walls are very thick and strong. The tunica media which is the thickest part of the wall contains huge amount of elastic fibres which enables the wall to stretch and withstand the blood surging out at high pressure.
This includes muscles, blood and skin, bones and teeth. Protein also helps regulate fluid balance, regulate acids and bases, carries oxygen from the lungs to the cells, work as source of energy and glucose, and works as antibody. Therefore, protein is an essential nutrient to the body. For this reason, Dawn needs to make sure that she is the consuming proper amount of protein. Furthermore, since Dawn wants to gain weight, an increase of the amount of protein can help her meet her
Protein have connection with amino acid to help in functions of: skin, muscle, hair and bones
The blood that is being carried away is very enriched with oxygen after it leaves the lungs and proceeds to the body’s tissues. The further the arteries get away from the heart they become smaller and more narrow and are eventually called arterioles. Arterioles and arteries just about have the same structure and function. Arterioles have strong, thick muscular walls and a rather small passageway for the blood to travel in and out. Also, they are the most highly regulated blood vessels in the blood and contain blood under high blood
Oxygen is going from the capillaries to the tissues, and carbon dioxide from. tissues taken up into the capillaries. Arteries have to be strong as well as flexible because of the pressure of the blood being pumped. through the venous system. Veins get bigger when they get closer to the heart of the world.
The body's blood consists of many components, red blood cells, white blood cells, plasma, and platelets. Red blood cells deliver oxygen to your body and remove waste. Without them, your body would slowly die. They contain a protein chemical called hemoglobin, which gives it it’s red color. Also, hemoglobin contains Iron, making oxygen molecules attach to it so as the blood passes through tissue...
When eaten, protein is broken down into amino acids. Proteins and amino acids are used for almost every metabolic process in the body, and are the building blocks for every tissue in your body.
The Functions of Proteins Introduction Protein accounts for about three-fourths of the dry matter in humans. tissues other than fat and bone. It is a major structural component of hair, skin, nails, connective tissues, and body organs. It is required for practically every essential function in the body. Proteins are made from the following elements: carbon, hydrogen, oxygen, nitrogen. and often sulphur and phosphorus.
The greatest lessons of the Vietnam war was America not letting the president overexert his power and we also learned that we should focus on things happening in our country before we go and pry in other country’s business, because these are the things the U.S. did not do and so many people lost so much respect in the government and we had so many internal problems in the U.S at the time of the Vietnam war and after the fact. The Vietnam war taught us to not let the president have too much power because in Vietnam most of America hated the war and each president just kept getting us in deeper. Like Reagan said "Government's first duty is to protect the people, not run their lives.” (Reagan).
Focusing attention on the elements of macrostructure of narrative production may best minimize the paradoxical disparity between speakers of AAE and African American narrative styles with the formal style of narrativization (Champion, 2003; Labov, 1972). Macrostructure refers to the general organization of the narrative with respect to themes, topic maintenance and thematic coherence (Glosser & Deser, 1992). Macrostructure encompasses all elements of microstructure, including story length in words, phrases and sentences; lexical diversity, and thematic cohesion (Glosser & Deser, 1992; Justice, et al., 2006). Ulatowska and Chapman (1994) noted that quantitity and distribution of information can be useful in the assessment of African American narrative
Protein helps build muscle, tissue, and organs. Without these critical elements, life on earth would cease to exist and
Proteins are considered to be the most versatile macromolecules in a living system. This is because they serve crucial functions in all biological processes. Proteins are linear polymers, and they are made up of monomer units that are called amino acids. The sequence of the amino acids linked together is referred to as the primary structure. A protein will spontaneously fold up into a 3D shape caused by the hydrogen bonding of amino acids near each other. This 3D structure is determined by the sequence of the amino acids. The 3D structure is referred to as the secondary structure. There is also a tertiary structure, which is formed by the long-range interactions of the amino acids. Protein function is directly dependent on this 3D structure.
INTRODUCTION What is a polymer? The term polymer comes from ancient greek, poly and mers meaning many parts. Polymer is a very large molecule comprising hundreds or thousands of atoms formed by successive linking of one or two, occasionally more, types of small molecules in chain or network structures. In Fig. 1, this specific molecular structure (chainlike structure) of polymeric materials is responsible for their intriguing mechanical properties.
