Answer:

e) the number of pairs of homologous chromosomes in a gamete.

Explanation:

A diploid cell is defined as the the cell containing two complete set of homologous chromosomes in a gamete.

In humans or other diploid sexually reproducing organism, sperm get fertilised with egg and produces  a gamete with two haploid sets of chromosomes form a complete diploid set.A human diploid cell has 46 chromosomes in 23 pairs.

Hence, the correct option is e)

How can the ethiopian wolves prey be classified as.<br><br> Dont say endangered plz
TEA [102]

Given what we know about the diet of the Ethiopian wolves, we can confirm that their prey can be classified as rodents.

<h3>What are Ethiopian wolves?</h3>
  • The Ethiopian wolves are a canine native to Ethiopia.
  • They are carnivores and hunt in packs.
  • Despite their name, they more closely resemble foxes or jackals.
  • They feed on rodents such as rats and hares.

Therefore, given their diet based primarily on animals such as hares, giant mole rats, and grass rats, we can confirm that the prey of the Ethiopian wolves can be classified as rodents.

15. During a routine cleaning of the incubators in a college laboratory, a student accidentally increased the tempe
diamong [38]

To test his hypothesis, the student will have to design an experiment to measure the effects of <u>temperature on cellular growth</u>.

To test the effects of temperature on cellular growth the student will have to create an experiment containing the there kinds of variables:

  • Dependent
  • Independent
  • Control

In this experiment, the control variable will be the kind of cells used, as well as the incubation methods being used. We identify these as the control variable given that they will remain constant.

The independent variable will be the Temperature at which we will place each cell being studied. The dependent variable, on the other hand, is by definition, what we seek to measure. In the case given it would correspond to the amount of cellular growth.

To test his theory of the effects of temperature on cellular growth, a student can design an experiment in which the control variable will be the cells themselves, the independent variable will be the Temperature, and the cellular growth can act as the dependent variable.

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.
