This cell contains all the genetic data that is required for the growth and development of a complete human being.The zygote is the first stage in the development process of a genetically unique organism that is genetically different from its parents.

Answer:
they are organisms that obtain energy by the oxidation of electron donors in their environment
Explanation:
Answer:
B
Explanation:
It's NAD+ because if you look at the electron transport chain, NADH delivers its electron to protein 1 (which causes NADH to turn to NAD+) and eventually those electrons move through multiple proteins to finally be accepted by Oxygen. If there's isn't oxygen, NADH won't be able to deliver electrons since those electrons wont end up anywhere. Which means NADH won't be oxidized (lose electrons) to turn into NAD+. NAD+ is necessary in citric acid cycle since it is reduced to turn into NADH.
