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>
there is no clear evidence about plants evolving in the desert, or fossils of any kind of cactus despite their distribution over a large area. But, scientists are of the opinion that they acquired specific attributes millions of years ago, as a response to the vastly changing climate and conditions.
-Desert plant root system
A typical desert plant has a deep root system, which is a specific physical mechanism. As the roots grow deep down the soil, they absorb soil water, which is then transported to the upper portions of the plant.
-Desert plant leaves
Bear small foliage with waxy surface to minimize transpiration (loss of water through stomatal pores), which in turn, helps to conserve water.
Natural disasters because they are all natural
B
because tRNA read the information from the mRNA to make the amino acid.
