How does the life cycle of a star compare to that of a human
solong [7]

Short answer:

It has a "birth" (in the nebula) just like humans are born inside their mothers.

It gets older and changes(in color which is due to its Temperature and in Size) just like humans as they go from babies to adults to elders. They also both die (Stars exploded or become black holes) stars "die out" and humans literally die. Both can die(not literally for stars) from old age.

Which statement correctly compares the transfer of genetic material during mitosis and meiosis?
guajiro [1.7K]

<span>d. During mitosis daughter cells receive an exact copy of the parent cells and during meiosis it only receives half of the genetic material.

</span><span>Mitosis and meiosis are simply cell division processes that occurs differently, they're characteristically divergent from each other according to their function and structure. Mitosis is the cell division that happens in all cells in the human body except sperm and egg cells. They produce diploid cells. Meiosis on the other hand is responsible for the cell division of the gametes, spermatogenesis (sperm cells) and oogenesis (egg cells), such haploid cells. </span>

In an experiment what should be the relationship between the control group and experimental group?
Sophie [7]

Answer:

Ideally, the experimental and control groups are identical. As much as possible, the two groups should overlap in every characteristic.

Explanation:

At the beginning of your study, you need your two groups to be as statistically similar as is humanly possible. That way, when you control for other variables, you can reasonably attribute any statistically significant differences at the end of the study to your intervention.
