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.

The suprachiasmatic nucleus influences the release of melatonin by its effect on the ________________.
anyanavicka [17]

Answer:

Pineal gland

Explanation:

The suprachiasmatic nucleus is the paired nucleus made of about 1000 neurons each in the hypothalamus. The suprachiasmatic nucleus is involved in maintaining the endogenous clock or the internal clock.

The suprachiasmatic nucleus controls the circadian rhythm by controlling the amount of melatonin. The melatonin is produced by the pineal gland from the serotonin and tryptophan precursors.  The hypothalamus thus controls the amount of the melatonin by regulating the pineal gland.

Thus, Pineal gland is the correct answer.

Frozen red blood cells that have been thawed, deglycerolized and reconstituted in an open system must be used within _______.
horsena [70]

Frozen red blood cells that have been thawed, deglycerolized and reconstituted in an open system must be used within 24 hours.

Cryopreservation of Red blood cells (RBCs) can be done with a long time span of usability of 10 years. Glycerol safeguards RBCs during freezing and defrosting, yet it can cause hemolysis if it is not washed off or eliminated before transfusion. When a unit has been deglycerolized, the shelf life of RBCs in an open system is only 24 hours, bringing about sporadic utilization of Frozen RBCs from the outset of the procedure or in close system cases it is up to 14 days.
