In two or more sentences, analyze why internal fertilization is more efficient than external fertilization?
almond37 [142]

Answer:

Although more offsprings are produced by the process of external fertilization but the process of internal fertilization is more efficient as compared to external fertilization. This is because, in external fertilization, it is more difficult for the sperm to find the egg and fertilize it. Even after fertilization, it might be that the zygote gets eaten up by a predator. There are none such risks in internal fertilization. The zygote is protected during the internal fertilization which makes this process more efficient.

Nerve agent

Explanation:

A nerve agent is a chemical in which on exposure to humans affects the functioning of the nervous system. These chemicals are known to disrupt the process by which messages are transferred to the organs from the nerve. This disruption occurs by blocking the activity of acetylcholinesterase, which is responsible for the catabolism of a neurotransmitter, acetylcholine.  

On exposure to a nerve agent, the muscles of the body become paralyzed and early symptoms is production of excess mucous such as in runny nose, pupil constriction and also difficulty in breathing.

These agents are sometimes used in chemical warfare. Examples include sarin, tabun etc.

How do the products of meiosis compare with the original cell? Think about chromosome number.
tatyana61 [14]
Well the offspring of the original cell are considered daughter cells (as they all reproduce) so with the knowledge I know when the cell doubles it’s going to look exactly like the mother cell and not just look but they all have the same job, which is to multiple. So I think that might be the answer. But if it’s multiple choice then I might be wrong because you didn’t provide any options.
