sattari [20]

Answer: Point mutation is easily reversible, thus non-lethal

Explanation:

Point mutation is caused by exchange of a single nucleotide for another. These change is called

1) Transition (when a purine base substitute another purine base, or pyrimidine bases substitute each other)

2) Transversion (when a purine base substitute a pyrimidine base).

However, note that a point mutation can be easily reversed by another point mutation; so, the claim that a nucleotide difference in the Hsr12 gene caused the human disease is inaccurate

Which of the following statements about biological membranes is FALSE? Which of the following statements about biological membra

Brrunno [24]

Answer:

Option (1).

Explanation:

Biological membrane mainly composed of lipids and proteins with the small amount of carbohydrate exposed on the outer surface of the membrane. This membrane plays an important role as it separates the cellular environment and facilitate the transport of the selected molecule.

The flippase enzyme is required to transport the molecules from one side of the membrane to the other membrane. Lipids and proteins can undergo lateral motion but at the different rate within the membrane.

Thus, the correct answer is option (1).

What happens to temperature and pressure when altitude increases?

timofeeve [1]

Answer:

Thus the air temperature is highest near the surface and decreases as altitude increases. ... Therefore, air pressure decreases as we increase altitude. The air density depends on both the temperature and the pressure through the equation of state and also decreases with increasing altitude.

The secretions of the adrenal medulla act to supplement the effects of ________.

Nutka1998 [239]

Answer:

sympathetic stimulation

Explanation:

Under stress or emergency conditions, the preganglionic neurons of the sympathetic division release acetylcholine. Acetylcholine stimulates secretion and release of epinephrine and norepinephrine from the adrenal medulla. These hormones enhance the effects of the sympathetic division of the autonomic nervous system (ANS) during stress. Epinephrine and norepinephrine augment the fight-or-flight response as they increase the heart rate and force of contraction, the output of the heart, and blood pressure. They also increase blood supply to the heart, liver, and adipose tissue. The airways to lungs become dilated and there are increase blood levels of glucose and fatty acids.
