The writer is concerned about the impact of chemicals on humans and animals.

Explanation: The new chemicals come from our laboratories in an endless stream; almost five hundred annually find their way into actual use in the United States alone. . . . Five hundred new chemicals to which the bodies of men and animals are required somehow to adapt each year, chemicals totally outside the limits of biologic experience.

Answer:

Yes.

Explanation:

Yes, the statement is right because in chemical war, great damage occurs to all living organisms that has a bad effect on our environment. These chemicals are very dangerous so its usage in the war has long term effects on the environment and the organisms that live in it. Both the opponents receive great damage from this chemical war and the destruction of the natural beauty of the place vanished where this war occurs so this vanished of beauty and organisms is the defeat of both the opponents that fought this war.

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.
