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.

These weeds are growing in a farmer's field. The weeds compete with the soybean plants the farmer grows, so he needs to get rid

Makovka662 [10]

Answer:

1) A mutation appeared in one weed plant that made that weed not susceptible to the herbicide ( B )

2) The weed will survive long enough to reproduce ( B )

Explanation:

1) The most likely reason the weed remained is : A mutation appeared in one weed plant that made that weed not susceptible to the herbicide

The weed plant must have undergone some mutation in order to be resistant to the herbicide which would kill the weed before now

2) The most likely thing that will happen if the weed stays in place in that farm is : The weed will survive long enough to reproduce

The trait or mutation of the weed cannot just spread to other weeds nearby it can only spread by reproducing more weeds of same mutation

The distance of a wave crest from its resting. position is its. out of

levacccp [35]

Assuming its "resting" is the place in the middle of the wave crest and trough, the distance between the crest and the middle line would be considered its amplitude. The height of a wave is the distance between the crest and the trough, and wavelength is the distance between two crests.
