In a physical change, the chemical bonds inside the material affected does not change. Same matter, just changed to look different. Like snapping wood in half.

A chemical change is when the chemicals are changed to re-arrange into different forms. An example of this is burning wood into ash. It cannot turn back into wood, it is only ash.

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.

Answer:

The best example of environmental influence that would most likely result in natural selection is that a food resource disappears in a pond, and some frogs in a population can eat the remaining food resource, while others cannot.

Explanation:

Among the environmental factors that can influence natural selection at a given time is the availability of food. Natural selection, from the point of view of evolution, is influenced by adverse environmental conditions, being food shortage one of them.

In conditions of food shortage in a pond, as in the example of the frog population, only the most apt will be able to take advantage of nutritional resources, while the less apt will not be able to survive. The ability to survive with little food available becomes an inherited trait that will be passed on to future generations.

In any case, tolerance to adverse conditions becomes adaptation, which translates into survival and reproductive success.
