The illustration below shows the steps of meiosis I.
Arlecino [84]

Answer:

According to the illustration of meiosis I, when sister chromatids stay together the phase to which it corresponds is telophase I (fourth option).

Explanation:

Meisois is a process of cell division whose final result is the obtention of two daughter cells with half of their genetic charge, with respect to the original cell. This process is divided into two parts, called meiosis I and II.

Telophase I corresponds to the phase of cell division in meiosis I, where the events that occur are the appearance of the nuclear membrane on the newly divided genetic material, cytokinesis -or cytoplasmic division- and above all due to the fact that each daughter cell already contains half of the genetic load, since the sister chromatids stay together.

Umnica [9.8K]

Answer:

The correct answer is option a, that is, cerebellum.

Explanation:

Alcohol acts as a CNS depressant. When more amount of alcohol is taken and the levels of alcohol rise within the body, some sections of the brain get influenced and a reduction in the functioning is witnessed in that particular part.  

The region of the brain accountable for coordinating movement and also some kinds of learning seems to be sensitive specifically to the consumption of alcohol. Thus, cerebellum is the part of the brain, which gets most affected due to the consumption of alcohol. Therefore, test is performed to witness the balance of an individual, as cerebellum is the part of the brain responsible for appropriate posture and balance.
