What are the phases in meiosis and explain
densk [106]

Cell division happens twice during meiosis. One starting cell can produce for gametes (eggs or sperm.) In each round of division, cells go through four phases called prophase, metaphase, anaphase, and telophase.

prophase During prophase the chromosomes become visible as paired chromatids and the nuclear envelope disappears. This phase includes reduction division, which is where the number of chromosomes is decreased from 46 (diploid) to 23 (haploid.)

metaphase This is where the 23 remaining chromosomes become attached to the spindle fibers.

anaphase During this phase, the chromosomes move away from each other to one or the other pole of the spindle fiber.

telophase In which the chromatids or chromosomes move to opposite ends of the cell and two nuclei are formed.

interphase This is a resting period.

Both intrasexual and intersexual selection usually cause changes in phenotypes for males and little changes in female phenotypes
saveliy_v [14]

<em>The question is incomplete. Please read below to find the missing content.</em>

<em />

Selection is usually strongest in the male of the species. D) because sperm are small and plentiful, while eggs are large and energy-rich.

Phenotype refers back to the observable traits of an organism as a multifactorial effect of genetic trends and environmental influences. The organism phenotype includes its morphological, biochemical, physiological, and behavioral residences.

A person's genotype is their specific collection of DNA. extra especially, this term is used to refer to the two alleles a person has inherited for a selected gene. Phenotype is the detectable expression of this genotype – a patient's clinical presentation.

The sum of an organism's observable traits is its phenotype. A key difference between phenotype and genotype is that, even as genotype is inherited from an organism's parents, the phenotype isn't.

Both intrasexual and intersexual selection usually cause changes in phenotypes for males and little changes in female phenotypes. Why is sexual selection usually strongest in the male of the species?

a. Males are naturally more aggressive

b. Males have a smaller genetic component than females due to fewer X chromosomes

c. Males do not pass on their mitochondria and therefore have more invested in each individual mating event

d. Because sperm are small and plentiful, while eggs are large and energy-rich.

Which of the following statements is NOT true regarding ATP production in muscles during periods of prolonged energy use, such a
Marysya12 [62]

Answer:

C.In the absence of oxygen, creatine phosphate can drive aerobic respiration pathways for a few minutes.

Explanation:

C. In the absence of oxygen, creatine phosphate can drive aerobic respiration pathways for a few minutes.

This statement  not true for a following reasons.

Firstly,  creatine phosphate directly phosphorylates ATP instead of providing any support for aerobic pathways.

Secondly, creatine phosphate stores are used up in about 15 seconds only. Thirdly, a cell does not need  oxygen deficit for creatine phosphate to be activated, it just needs to be short on ATP.

aalyn [17]

Answer:

hippocampal place

Explanation:

A type of cell that fires when rats are in a specific location as opposed to some other locations are known as place cells.

Generally, place cells are specially shaped neurons whose origin is the hippocampus. These neurons fire or become more active when animals are in certain locations in its environment, as opposed to their overall environment.

The cells are from regions CA1 and CA3 of the hippocampus and collectively act as a cognitive representation of these locations where they are limited to firing. The locations where the neurons are limited to firing are referred to as place fields.

Hence,<u> the cells found in the rat as shown by the illustration are referred to as the place cells whose origin is the hippocampus.</u>
