Answer:

Mutation- A change in genetic structure of a organism is called as mutation.

It can be inherited to offspring if it is germline or germinal mutation , mutation that occurs in germ cells like sperm and ovum.

Explanation:

Each of the genes of a child is the copy of his parents, one from mother and one from father. Any kind of changes or mutation in any genes of them can be inherited to child

Mutations caused by environmental factors can not transferred to next generation. Mutation caused by UV radiation, smoking, sunlight are non inheritable..

Answer:

According to the diagram, what is occurring in step 7 is cytokinesis, with the separation of two daughter cells, following cell division.

Explanation:

Cytokinesis is a process that occurs at the end of mitosis or meiosis, being the final step of cell division. This mechanism allows the separation of the two daughter cells, with equal distribution of cytoplasm and formation of cell membrane, differentiating into two independent cells.

In the diagram it can be observed (step 7) that after the division process —in yellow— two arrows pointing to two cells are evident, which implies the process of cytokinesis.

Prior to the cytokinesis process, karyokinesis occurs, which is the separation of nuclei and formation of the nuclear membrane.

In animal cells, karyocinesis occurs by the effect of a ring of actin and myosin that helps to force the separation. In the plant cell, the fragmoplast is formed, a septum that induces the separation of the daughter cells.

The other options are not correct because:

Cell growth occurs in G1 phase.
Cell preparation occurs in interphase.
DNA replication occurs in S phase.
Mitosis is represented in yellow, and involves 4 phases.

Which one is the correct Answer???

Rom4ik [11]

Answer:

I'm pretty sure the answer is 4.

Explanation:

1 and 2 are definitely homeostasis because it is a way to keep your body balanced how it needs to be and 3 would be a natural reaction that your body would make to prevent further pain, but 4 would be a personal choice that is made by the person who stays up.
