There is one choice missing from this question:
<span>a. narcoleptic fits
b. nightmares
c. apnea episodes
d. night terrors*
The correct answer is "night terrors". Night terrors are intense feelings at the first half of non-REM sleep that is characterized by fear, horror, trembling, shaking. Night terrors are different from nightmares as there are physical effects carried out from night terrors upon waking up such as screaming, crying, and sudden movements.</span>
The correct answer is the second choice - peer review process in scientific research exists in order to verify that the conclusions that are made are supported by the data. You cannot make a valid conclusion if you do not have enough evidence or data to prove it - this is why your peers have to go through your research to make sure everything is done according to the rules of scientific research.

B is the answer to this question. Hope this helps.
Answer:
The correct answer will be- zygote →cleavage→ morula→ blastula→ gastrula.
Explanation:
Human embryogenesis is the study of the formation of an embryo from the zygote formed after the fertilization of the sperm and egg cell.
The fertilization takes place in the ovarian duct in females which form a diploid zygote. The zygote starts the process of cleavage that is cell division and differentiation and leads to the formation of a 2 celled stage, 4 celled stages and later 16 celled stage. The 16 celled stage is known as morula which further undergoes cleavage and form blastula. The blastula now forms a gastrula with 3 layered distinction- the ectoderm, endoderm and mesoderm through gastrulation.
Thus, zygote →cleavage→ morula→ blastula→ gastrula is the correct answer.
