Answer:
The electron density of a polar bond accumulates towards one end of the bond, causing that end to carry a slight negative charge and the other end a slight positive charge. Likewise molecules in which there is an accumulation of electron density at one end of the molecule, giving that end a partial negative charge and the other a partial positive charge, are called polar molecules.
Answer:
Nutrients makes the most sense.
I would guess rainforest because it’s an reptile/amphibian it appears and those animals need water to survive. There isn’t much water in the dessert.
Answer:
Most hormone feed back is a negative feed back mechansm, A feed back mechanism is a form of a signal mechanism loop where product feed back to control its own production.
Explanation:
For example pancreas is an important gland in an endocrine system which relies on negative feed back to regulate blood glucose level in the body to keep it within the required healthy range.
The answer is B
Before the process of translation occurs, mRNA which bears the blue print or coded information for the synthesis of a specific protein arrives from the nucleus and into the cytoplasm where there are ribosomes
mRNA then attaches itself to a ribosome. The ribosome is the site where the protein is formed. It is sometimes referred to as the "work bench" of the cell. Once mRNA is attached, tRNA comes and begins to read and translate the coded information on the mRNA. This is the translation stage of protein synthesis.
Based on the translated information, tRNA then fetches amino acids from the pool of free amino acids found in the cytoplasm and brings them to the ribosome where they are joined to form a chain thus creating a protein.
