g During the G2 stage of interphase, ___ does not occur. A. organelle replication B. DNA growth C. protein replication D. cell g
ArbitrLikvidat [17]

Answer: DNA growth does not occur

Explanation:

Here, the cell has grown, the DNA has been replicated (this takes place in the S phase of interphase) and its almost time for the cell to divide. Basically, what occurs during the G2 phase (Gap 2 phase of interphase) includes duplication of all proteins and organelles needed later during the process of cell division. Some of these includes assembly of microtubles will later for the spindle structure that that helps in the separation of chromosomes during the M phase but these are produced during the G2 phase.

The cells also continue to increase/grow in size and the volume of the cytoplasm also increase in this phase. There is also a checking where the cell needs to check for the structures and components and to also ensure that they are all present

Evolution creates not the best solution but the most available. Building on your answer to the previous question what does this
Greeley [361]

This statement means that evolution has happened by getting the genes of the  right trait expressed at the right time to help adaptability.

Explanation:

Evolution is a result of natural selection which emphasize on the survival of the fittest. But the occurrence of this trait has been possible with genetic variation. It means that if the genes for the particular feature is not present in the genome how would it occur and adapt to the environment. Thus, evolution promotes the most available option for the adaptation and hence for natural selection.

We can conclude that all features are not adaptable some are the results of genetic drift or mutations.

In case of cheetah,  the faster running genes would have been there they got expressed over the period of time for better adaptability.

Imagine that a rancher has a herd of cattle with brown hides and short horns. All of his cattle are also relatively short in sta
dmitriy555 [2]

Answer:

The correct answer would be option D.

Explanation:

True breeding is a breeding procedure in which the parents would always produce their progeny with the same phenotype characters as the parents carry. This means for every trait these parents are homozygous so their offspring must show a similar phenotype.

In this case, all cattle are true-breeding which means they homozygous alleles show the progeny will also show similar traits which are short stature with brown hides and short horns.

Thus, the correct answer is option D.
