Answer:
The answer is C: primary oocyte
Explanation:
Ovogenesis is the process by which the ovary gives rise to a mature ovum (oocyte). The primary oocyte is the first to form during ovogonia, once the process of meiosis begins. It is compared with spermatogonium as it is also the initial phase for sperm formation.
Answer:
Yes, a subtle one.
Explanation:
Symptoms of a panic attack are intense and disruptive. They often involve a sense of “unreality” and detachment. Anxiety symptoms vary in intensity, from mild to severe. Panic attacks appear suddenly, while anxiety symptoms become gradually more intense over minutes, hours, or days.

True

Answer:
Correct answer is c. It is the final electron acceptor in the aerobic respiration.
Explanation:
Oxygen is a substrate of the aerobic respiration, but it is not the only one. Glucose is also a substrate.
Oxygen is used in the cells to be the final electron acceptor, this means that receives the electrons from NADH and FADH2. That is why, when there is no oxygen available for aerobic respiration, the NADH and FADH2 cannot be oxidized and therefore remain in their reduced form. As a consequence, they cannot be re-utilized during different cellular processes that are NAD+ and FAD dependant, such as glycolysis, pyruvate oxidation and cellular respiration. This means that the ATP synthesis stops.
Oxygen itself does not transport any electrones, this are transported by the cytochrome complex in the mitochondrial membrane. But oxygen is key in receiving those electrones, therefore a very important piece of the electron transport across the mitochondria.
