xxMikexx [17]

Answer:

The binding of a neurotransmitter on a postsynaptic cell allows potassium ions to diffuse out of the cell. This would result in a NEGATIVE CELL MEMBRANE POTENTIAL which is an HYPERPOLARIZATION event.

Explanation:

The binding of a neurotransmitter to a postsynaptic cell results in a group of channels in the cell membrane called ligand gated channels open or close in response to that binding.

Hyperpolarization occurs when a ligand gated channel opens and allows potassium ion to flow out of the cell.

During hyperpolarization, potential of the cell membrane experience changes which makes it to become more negative.

During which phase of meiosis does each of the following events occur?
lubasha [3.4K]

Answer:

(a) crossing over: Meiosis I, Recombination  

(b) chromatids separate at their centromeres and migrate to opposite poles: Meiosis II, Anaphase II

(c) chromosomes become aligned in pairs at the equator: Meiosis II, Metaphase II

Explanation:

Homologous recombination is a type of genetic recombination that occurs during meiosis (formation of ovum and sperm cells). The paired chromosomes of the male and female parents are aligned so that similar DNA sequences intersect. This crossing over produces an exchange of genetic material, which is an important cause of the genetic variability observed in the offspring.

Meiosis II: Anaphase II. The centromeres separate and the daughter chromatids - now individual chromosomes - move to the opposite poles of the cell. The centromeres separate, and the two chromatids of each chromosome move toward the opposite poles in the spindle.

Meiosis II: Metaphase II. Chromosomes are accommodated in the equatorial plate of metaphase, similar to what happens in mitosis. They are attached to the already fully formed meiotic spindle. Each chromosome is aligned in the equatorial plate of the metaphase, as it happens in mitosis.
