72 chromatids were present in the present in the primary oocyte during  prophase 1 of meiosis.

The primary oocyte contains 72 chromatids during prophase 1 of meiosis as the mature ovum has 18 chromosomes.

The primary oocyte contains 72 chromatids , that means it contains 144 chromosomes. During the first meiotic division, it produces one secondary oocyte and one polar body.

The secondary oocyte  has 72 chromatids, which again undergoes second meiotic division and produces mature ovum and second polar body . The mature ovum contains contains 36 chromatids which means it has 18 chromosomes.

Galina-37 [17]

Answer:The timing of the cricket's depends on the temperature of the box

so the answer should be

timing of the cricket's chirps

Explanation:Hi!

There are a few types of variables in these types of experiments. They are independent, dependent, and controlled.

The independent is the one changed by the scientist, or in this case, the temperature. The controlled is the things that remain constant through every case, and the dependent is what is being observed, seeing if it changes through the altercation of the independent variable.

In this case, what is being observed is the timing of a cricket's chirps, because it is being watched whether or not temperature affects it.

Therefore, your answer is the third choice, or the timing of the cricket's chirps.

Hope this helped!
