The initial increase in heart and breathing rates during the skin diving trip was probably a result of: a. activation of the sym
pathetic autonomic nervous system by the new experience. b. activation of the parasympathetic autonomic nervous system by the new experience. c. hypoxia caused by the inability of her blood hemoglobin concentration to supply sufficient oxygen for the strenuous exercise of swimming at sea level. d. elevated core body temperature caused by swimming in warm tropical waters.
a. activation of the sympathetic autonomic nervous system by the new experience.
Explanation:
The sympathetic division of the autonomic nervous system generates a flight or fight response. This is a series of physiological processes that start when a person has any stress, new experience or emergency conditions such as the first diving trip. One such response produced by activated sympathetic division is increased heart rate to pump more blood and deliver more oxygen to body cells and tissues. Also, the person experiences an increased breathing rate to compensate for the increased oxygen demand.
Mutation. Mutations are changes to an organism's DNA and are an important driver of diversity in populations. Species evolve because of the accumulation of mutations that occur over time. ... Some mutations are unfavorable or harmful and are quickly eliminated from the population by natural selection.
The amino acid chain will be formed by the codons AAU AAG GAC is Asparagine- Lysine-aspartate. Amino acid consists of one carboxyl group that is COOH and one amino group (NH3)
