<span>The scientist who melted glass to simulate a microscope was Robert Hooke, in 1660. He was an English physicist, and he looked at insects and handheld objects. He named the cell for the cell of a monk, because to him it appeared to be a self-contained room.</span>

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 <u>separation of the two daughter cells</u>, 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:

  • <u><em>Cell growth</em></u><em> occurs in G1 phase.</em>
  • <u><em>Cell preparation</em></u><em> occurs in interphase.</em>
  • <u><em>DNA replication</em></u><em> occurs in S phase.</em>
  • <u><em>Mitosis</em></u><em> is represented in yellow, and involves 4 phases.</em>
