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:
1.capsule
2.membrane composed mostly of lipopolysaccharide
3.membrane composed mostly of phospholipids
4.peptidoglycan
Explanation:
The cell wall of gram-negative bacteria is located outside the cell membrane and is composed of a single layer of peptidoglycan, followed by a second membrane composed of phospholipids (often called outer membrane) and finally a lipopolysaccharide layer, these three elements constitute the gram-negative envelope. Also, some bacteria produce a viscous secretion that spreads in the surrounding environment, forming a slime layer known as a capsule.
Answer:
The rock of the Great Plains is sedimentary rock and the rock of the Rocky Mountains is igneous rock. They formed in different ways so they must not have formed together. When sediment is compacted and cemented together, it forms sedimentary rock. When magma cools, it hardens to form igneous rock.
Explanation:
Answer:
ΔG°' for the conversion of citrate to α-ketoglutarate = - 273.64 kJmol-1
Explanation:
ΔG°' for Citrate is +6.64 kJmol-1
ΔG°' for Isocitrate is -267 kJmol-1
ΔG°' for the conversion of citrate to α-ketoglutarate = ΔG°' for product - ΔG°' for reactant
ΔG°' for the conversion of citrate to α-ketoglutarate = -267 kJmol-1 - (+6.64 kJmol-1)
ΔG°' for the conversion of citrate to α-ketoglutarate = - 273.64 kJmol-1
