Answer:
The veins and arteries encounter differences in the pressure of the blood flow. As a consequence, these differences are seen in the composition of the vessels. The arteries encounter with a pressure wave as blood gets pumped from the heart. This can be experienced as a pulse. Due to this pressure, the arteries' walls are much thicker in comparison to those of the corresponding veins.
Thus, arteries appear to exhibit more uniform shape, they seem to be more circular in shape in comparison to veins. Veins do not encounter with the pressure waves like the arteries do. Thus, they do not require to be structurally strong. The vessels' walls of veins are thinner in comparison to arteries and do not exhibit much tunica media.
The answer is cytologist.
A cytologist is an expert in cytology. Cytology is a branch of life sciences that studies cells, including their structure, function, and chemistry. Thus, the cytologist is expert in cell function and structure. Therefore, every process in which cells are involved, such as processing sugars, would be a research target for the cytologist.
Answer: Option D
The peroxisome functions in macromolecular biosynthesis and breaks down fatty acids and other organic compounds.
Explanation:
Peroxisome are cellular organelles that play roles in metabolic process such as oxidation of lipids to yield simple products of carbon dioxide and water.
It also helps in the synthesis of biotin, a vitamin that activates many enzymes catalysing several cellular reactions.
Answer:
1. Behavioral Adaption
2. Psychological Adaption
3. Structural Adaption
Explanation:
Adaption can protect animals from predators or from harsh weather. Many birds can hide in the tall grass and weeds and insects can change their colour to blend into the surroundings.
It makes sure they are in perfect condition for it to go through the cell cycle easier
