Answer:

Explanation:

D is not correct because the atmosphere doesn't expand, C isn't correct because the Sun doesn't heat all the Earth evenly (hence different climates), B is not correct because cold fronts can be singular, so it has to be A

Cell division is represented where

Answer:

During the telophase stage, the spindle fibres lengthens more and the nuclear membrane reforms to form the nuclei enclosing the separated sister chromatids. And, later followed by cytokinesis which involves the division of cytoplasm and yields the 2 daughter cells

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.
