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.

How does information flow through the most common type of cns neuron (iist the 3 regions in the proper order)?

steposvetlana [31]

First of all, the most common type of CNS neuron is the multipolar neuron meaning it has many dendrites and dendritic branches, a cell body or soma, and a single axon. The information flow through this neurons starting from receiving multiple impulses from multiple synapses since this kind of neurons has many dendrites. The signal will then flow in an anterograde manner meaning the multiple signals will flow towards the cell body or the soma to be integrated. Next is that the integrated signal will flow to the neuron's axon to be transmitted to other neurons.
