After erection, semen release is a two-step process.

Biology
1 answer:
Mnenie [13.5K]3 years ago
7 0

Answer:

Emission

Explanation:

Semen contains sperm and the secretions released by the accessory sex glands such as seminal vesicle and prostate gland. Before the ejaculation of semen, the muscles of the epididymis, ductus deferens, seminal vesicles, ejaculatory ducts, and prostate gland exhibit peristalsis. This results in the release of the secretions from the accessory glands and reproductive duct into the urethra. Since semen is present in the urethra, a small volume of semen is discharged even before ejaculation during emission.

Because of genetic variation, a species of beetle has two different body colors, red and green. This species exists in a grassy
pshichka [43]

Answer:

1. Green beetles and red beetles exist in the environment.

2. Birds that eat the beetles move into the environment.

3. Red beetles are eaten by birds, but green beetles aren’t eaten.

4. Green beetles pass on their color trait to future offspring.

5. The entire population of beetles eventually becomes green in color.

Explanation:

According to the theory of natural selection, only those species survives which fits closely with their environment. According to the conditions given, there are two genetic variations of the same species based on the color, i.e. green and red. Initially, both red and green are living together in a grassland (green in color). Then, birds enter the same environment because they have food there (beetles). Now, green beetles will take a competitive advantage because of the color and avoid getting eaten by the birds. However, red beetles would be prominent and eaten fast. The green beetles will pass on their genetic variation causing the color to be green in their future offspring and a time will come when there will be on green beetles in the area.

Horses and donkeys can mate but they produce a mule, which is always a sterile animal. This means that they cannot produce viabl
Morgarella [4.7K]
They are genetically and reproductively isolated. For the mule the specific isolation mechanism is termed as "Hybrid Inviability", where the postzygotic isolating mechanism prevents the hybrid from passing on their genes. A zygote may form with the sperm and egg, but the embryo will dies after a few cell divisions. The genetic information from male and female parents is insufficient to carry the organism through morphogenesis. *There are rare documented cases of a mule producing a viable offspring.
