Two insect groups vary genetically by two genes. When put together,they were able to reproduce and produce offspring that could
nikitadnepr [17]
<h3>Your answer is D.</h3>

The insects are the same species.

<h3>Explanation:</h3>

A species is a group of similar organisms able to reproduce (to exchange genes and interbreed) only within the group. That means that organisms from different species could not exchange genes. Since mentioned insect groups are able to reproduce and produce offspring that could also breed, these groups belong to the same species. If they could not reproduce and produce offspring that could also breed, these groups would belong to the different species.

I hope I helped, and I always appreciate Brainliest!!! :)

<h2>Cell Cycle </h2>

Explanation:

Eukaryotes grow and divide by cell cycle.

The main parts of a cell cycle are an ordered series of events – Gap 1 or G1 phase, Synthesis or S phase, Gap 2 or G2 phase, and the mitosis or M phases.  

Interphase period (G1, S, G2 phases) - cell grows by size, duplicates its content, replicates its DNA, and finally prepares for mitotic cell division .

Mitosis and cytokinesis - formation of two identical daughter cells

Cell cycle is regulated by regulatory or restrictive checkpoints in the cell cycle which are activated with detection of a defective DNA.

Proliferation of undesired or cells with defective DNA like in case of tumor cells is controlled by the action of suppressing agents like p53 and cyclins.

The tumor suppressor gene protein p53 prohibits division of tumor cells. Cyclins regulate cell cycle by activation of the enzyme cyclin-dependent kinase.
