Which phase of mitosis is the last phase that chromatids are together

Biology
1 answer:
Vladimir [108]3 years ago
4 0

Answer:

Metaphase

Explanation:

The M phase of the cell cycle is the phase during which the nuclear content and cellular content is distributed. The distribution of the nuclear content takes place in four phases: prophase, metaphase, anaphase and telophase.

The homologous chromosomes are aligned at the equatorial plate during the metaphase after which the chromosomes separate. The phase during which the separation of the chromosomes takes place is known as anaphase so the phase before the anaphase is the phase during which the chromatids are not separated that is the metaphase.

Thus, metaphase is the correct answer.

If the frequency of an allele is 0.75, how many copies of this allele should be in a population of 300 diploid individuals?
Ray Of Light [21]

I have provided the options below:

a. 150

b. 225

c. 300

d. 450

e. 75

Answer:

150

Explanation:

Hardy-Weinberg law states, the allelic frequencies of a gene that is, q and p follow the relationship p^2+q^2+2pq = 1, if the population is in equilibrium.

Therefore p^2+q^2+2pq = 1, can be used to calculate the percentage of the allelic frequencies i.e. p^2 and q^2

Allelic frequency = 0.75.

Therefore, the percentage of the allele in the population would be given by

0.75^2 = 0.5625 = 56%.

And the total number of individuals with this allele in the population:

number of individuals = 56×300÷100

= 168 or

150 nearest figure.

Four hundred beetles of the same species were sprayed with an insecticide. Several weeks later, nearly all the beetles were dead
Kamila [148]

Answer:

D

Explanation:

Just trust me.  

it's not A because there's no such thing as favorable traits whenever it comes to incesticide and for B the majority of Beatles and future generations will also die that's only to the ones that died but that can not happen, which means that D is the one that will be the correct answer because if one lives, then the rest of the generations live due to immunity in the generation that started it.
