Answer:

UV radiation may cause negative regulators (tumor suppressors) to be under-expressed. UV radiation may cause positive regulators (oncogenic) to be over-expressed.

Answer:

Explanation:

Lower frequency for both dewlap extension and pushups. In the presence of predators and females an increase in the dewlap frequency and pushups is expected as a result of defense and breeding mechanisms mixed while in the second situation we have just breeding mechanisms involved

"it is possible to combine two or more plant proteins with different essential amino acids to yield a complete protein."

leonid [27]

Yes i believe it is possible. Complete proteins are proteins with all the indispensable amino acids present in proper proportions; for example in foods like eggs, meat, fish, milk. Incomplete proteins on the other hand are food proteins that contain a limiting amount of one or more indispensable amino acids needed for growth; for example corn tortillas are lacking in lysine. It is possible to make a complete protein by combining together two incomplete protein foods in the same meal.

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.
