Answer:
During depolarization, the membrane potential rapidly shifts from negative to positive. As the sodium ions rush back into the cell, they add positive charge to the cell interior, and change the membrane potential from negative to positive.
Explanation:
Ovulation and ejaculation are the processes that involve the release of the female and male gamete for the process of fertilization.
<u>Ovulation</u>
- The release of an egg from one of a woman's ovaries is known as ovulation.
- Ovulation usually lasts for one day and takes place two weeks before a woman anticipates getting her period, in the midst of her menstrual cycle.
- However, the procedure takes a different amount of time for every woman, and it might even change from month to month.
- A sperm cell can fertilize an egg when it exits a woman's ovary and enters the fallopian tube.
- Sperm can survive for three to five days inside a woman's reproductive system.
- The uterine walls thicken during ovulation in order to accommodate a fertilized egg. On the other hand, if the egg is not fertilized, the uterine lining is lost around two weeks later, which results in menstruation.
<u>Ejaculation</u>
- Ejaculation, the male reproductive system's discharge of sperm cells and seminal plasma.
- Sperm are transported from the testicles and the epididymis, where they are stored, to the beginning of the urethra, a hollow tube that runs through the pen!s and transports either sperm or urine.
- In the second stage, known as the actual ejaculation, the semen is transported through the urethra and expelled from the body.

Answer:
B
Explanation:
<u>The correct statement to be inferred from the information would be that all eukaryotic cells need to produce energy</u>.
<em>The mitochondrion is an organelle that is referred to as the powerhouse of the cell. It is the site of oxidative phosphorylation where the energy for the cell's metabolic processes is generated. Hence, if all eukaryotic cells have mitochondrion, it means that they all need to produce energy for their metabolic activities.</em>
The correct option is B.
