Dilated pupils, inhibited digestive activity, increased respiratory rate, and release of glucose from the liver are all signs of
activity of: A. both divisions of the autonomic nervous system.
B. the somatic nervous system.
C. the sympathetic division of the autonomic system.
D. the parasympathetic division of the autonomic system.
C. the sympathetic division of the autonomic system.
Explanation:
The sympathetic nervous system is one of the divisions of the autonomic nervous system that controls involuntary body functions in the body. The sympathetic nervous system is said to stimulate the fight-or-flight response of the body when the body senses threat, or is exposed to a stressor. These fight-or-flight responses are generated in the body in form of physiological changes in order to put the body at top alert to focus on dealing with the stressor.
Physiological changes that are stimulated by the sympathetic nervous system as fight-or-flight responses include dilated pupils, inhibited digestive activity, increased respiratory rate, and release of glucose from the liver, which are all stated in the question. It is the sympathetic division of the autonomic nervous system that controls all these activities.
During prophase, which occurs after G2 interphase, the cell prepares to divide by tightly condensing its chromosomes and initiates mitotic spindle formation. The chromatin fibers condenses into discrete chromosomes. The nucleolus also disappears during early prophase.
C. All living organisms likely originated from a common ancestor ( because all living organisms store genetic information through DNA and RNA. These are linked to a shared ancestry and is how organisms evolve using new genes )
