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.

Which sequence correctly depicts the development of offspring?
JulijaS [17]

Answer:

The correct answer would be zygote...blastocyst...embryo...fetus.

The fertilization of sperm and egg results in the formation of zygote. It receives genetic material from a male as well as a female parent.

It divides with the help of mitotic divisions and results in the formation of 2, 4, 8, and 16 celled stages.  

It results in the formation of the hollow spherical ball of cells termed as a blastocyst.  The cells are distributed to form the outer layer termed trophoblast and inner cell mass which gives rise to the embryo.

Trophoblast help in the implantation of the blastocyst into the uterine wall.

The cells of the embryo undergo organogenesis during different organs such as heart, brain, lungs et cetera are formed.

In humans, almost 9 weeks after the fertilization the developing embryo is considered a fetus.  

The fetus development continues until birth.
