Answer:

The genome in which a genotype is found can affect the expression of that genotype, and the environment can affect the phenotype. Genes can also be pleitropic when they affect more than one trait. The single base pair mutation that lead to sickle cell anemia is a classic example.

Answer: population

Explanation: An organism's genotype is the set of genes that it carries. ... However, since an organism's genotype generally affects its phenotype, the phenotypes that make up the population are also likely to change. For example, differences in the genotypes can produce different phenotypes.

Explanation:

A nucleus present in the pons of brainstem responsible or involved in physiological responses to panic and stress is known as locus ceruleus.

Basically, locus ceruleus is responsible for the primary production of norepinephrine in the brain. The nucleus transfers the norepinephrine to whole cerebral cortex along with various other structures like amygdala, cerebellum, hippocampus, and spinal cord.

So, when there is a panic disorder due to norepinephrine dysregulation at the brainstem area which will be definitely locus ceruleus.

fgiga [73]

Answer:

ribosome, cell membrane, nucleus

Explanation:

The organelles that perform similar functions in both plant and animal cells among the listed organelles would be the ribosome, the cell membrane, and the nucleus.

First of all, chloroplast and cell wall are limited to the plant cell only. Animal cells do not have these organelles.

The ribosome functions as the site of protein synthesis in both plant and animal cells. The cell membrane acts as a channel for the control of the movement of materials in and out of the cells and is found in both plant and animal cells. The nucleus is also present in both cells and serves as the control unit of the cell by housing the genetic materials and dictating how the cells will behave.
