Answer:
Enzyme- Peptidase/protease
Explanation:
According to this question, a student is conducting an experiment to determine the roles of molecules in metabolic processes such as digestion. Based on what she found out that the molecule, which itself can be broken down into amino acids, can also break down proteins into amino acids, this suggests that the molecule being described is a PROTEOLYTIC ENZYME.
This is because an enzyme is made up of proteins which can be denatured or broken down into its simplest unit (amino acids) and also, a substance that breaks down amino acid is said to be PROTEOLYTIC.
However, another observation that the molecule is found in high concentrations in the small intestine was made, hence, the enzyme is a PEPTIDASE OR PROTEASE, which are secreted into the small intestine by the pancreas to aid digestion of proteins.
<span>The myelin sheath allows nerve impulses to propagate very quickly along a nerve's axon to transport the signal between nerve cells. The myelin coating allows the chain reaction of impulses to jump certain distances instead of waiting for the chemical changes to happen at all points on the axon.</span>
<span>Sunlight emits light energy which is absorbed by the thylacoids in
the chloroplasts of a plant. Chloroplasts are organelles in a plant
cell whose funtion is photosynthesis (the use of light to make
energy). Thylacoids are a part of the chloroplast which absorbs
light. The thylaciods convert the light into energy molecules NADPH
and ATD. The Calvin cycle then takes place in the stroma
(gellatinous matrix of the chloroplast). The Calvin cycle is the
use of ATP and NADPH plus carbondioxide to produce starch. Starch
is the polysaccharide sugar formed from glucose synthesized in a
linear chain. The starch is the storage of the glucose which is
used as an energy source for the plant cells. </span>
The answer is C. lipid membrane
The reason for this is, as stated in your question, it is called a phospholipid bilayer.
It's called like that because it is made out of lipids and it also has phosphate groups, while the bilayer part means it just has two layers. Therefore it is commonly also called a lipid membrane.
A physical characteristic of a fish would be B) Fins.
