Answer:
met is the answer bro did you understand
Biochemistry is the study of the actions of the main metabolic processes of living organisms, which are protein synthesis (DNA and RNA molecules, genetic codes and how they work, enzyme formation and function, etc), glycolysis (cellular respiration, aka the Krebs cycle/citric acid cycle to break down glucose molecules to release chemical energy and oxydative phosphorylation, the use of that chemical energy to form ATP molecules in which the chemical energy is put in a form the cell can use, and lipid chemistry (the study of the pathways in which fatty acids are formed into lipids and fat molecules and cholestrol formation and function).
Essentially, biochemistry covers the chemical reactions necessary for cellular and organism metabolism
Answer: Vestigial structures
Explanation: Vestigial structures are an anatomical feature or behavior that no longer seem to have any purpose in the present form of an organism in the given species. Usually, they are often parts of the body that used to preform important functions in earlier forms of the organism.
B). A population changes in response to a change in the environment.
Low molecular weight heparin is associated with less thrombocytopenia than the normal heparin. Low molecular heparin also prevent unnecessary bleeding since it is not as strong as the normal heparin. Low molecular weight heparin are derived from smaller polysaccharide chain and their effect is more predictable than the normally unfractionated heparin. It also help treat deep venous thrombosis, which is commonly associated with prolonged sitting and standing. It is also used to treat pulmonary embolism especially the more massive one. However, care must be observe in using it since some patients elicit allergic responses to it.
