Biology

Nadya [2.5K]2 years ago
5 0

Answer:

Homologous pairs of cells are present in meiosis I and separate into chromosomes before meiosis II. In meiosis II, these chromosomes are further separated into sister chromatids. Meiosis I includes crossing over or recombination of genetic material between chromosome pairs, while meiosis II does not.

In meiosis I, homologous chromosomes separate, whereas in meiosis II, sister chromatids separate. Meiosis II produces four haploid girl cells, whereas meiosis I produces a pair of diploid female offspring cells. Genetic recombination or crossing overonly happens in meiosis I.

Hope it helps!<3

A scientist thinks that a certain chemical is a mutagen. She exposes plant cells to a large amount of this chemical in the labor
PSYCHO15rus [73]

A mutation is an alteration in the original DNA sequence.  Option 3. The cells change after being exposed to the chemical, and this change is passed to the next generation of cells.

<h3>What is a mutation?</h3>

A mutation is a stable and hereditably change in the genetic material.

Mutations alter DNI sequences and introduce new variants. Many of these variants are eliminated, but some of them might succeed and be incorporated in each individual, affecting the entire species.

They can be damaging or beneficial. These last mutations are the ones that have been selected by natural selection.

Different mutagenic agents cause changes in genetic information, increasing mutations over the normal level. They can change the bases sequences and bases pairing.

Mutations depend on each group's environment and its ecological pressures, and they accumulate in time. They are inherited to the followings generation and get to spread.

According to this framework, the correct option is 3. The cells change after being exposed to the chemical, and this change is passed to the next generation of cells.

If the analyzed chemical is a mutagen, then it will cause an alteration in the DNA sequence and this change -mutation- will pass to the following generations spreading in the population.

A scientist thinks that a certain chemical is a mutagen. She exposes plant cells to a large amount of this chemical in

the laboratory

Which statement best provides evidence that the substance is a mutagen?

  1. The cells die within hours of being exposed to the chemical.
  2. The cells grow more quickly than those that were not exposed to the chemical.
  3. The cells change after being exposed to the chemical, and this change is passed to the next generation of cells.
  4. The cells continue to divide at the same rate as before they were exposed to the chemical.
