Harry is driving on the interstate highway for the first time since he obtained his license. he is nervous and wants to get off the interstate but cannot do so; his heart and pulse are racing. in this scenario, harry's physiological responses can be best attributed to his nervous system.
a) sympathetic
b) parasympathetic
c) somatic
d) central

The correct answer is letter A: sympathetic nervous system.

Explanation:

The autonomic nervous system is composed of the parasympathetic and the sympatetic systems. The parasympathetic is responsible for stimulates “rest-and-digest” activities, which occur during body rest, such as slowing heart rate and lowering blood pressure, adrenaline and blood sugar. The sympathetic responses for “fight-flight-or-freeze” situations. The sympathetic system acts directly (via impulses transmitted by the sympathetic nervous system) and indirectly (via catecholamines) on the cardiovascular system, leading to accelerate heartbeat. Thus, Harry’s physiological responses can be attributed to his sympathetic nervous system.

interphase   is the cell cycle stage in which the cell acquires nutrients, creates and uses proteins and other molecules and starts the process of cell division by replicating the dna. it is the longest stage in the eukaryote cell cycle.

the following   can go wrong during interphase:   a base pair could be mismatched during the duplication process causing a mutation.   correct answer: c

explanation:

mountains can affect the climate of nearby lands. in some areas, mountains block rain, so that one side of a mountain range may be rainy and the other side may be a desert. much of airborne moisture falls as rain on the windward side of mountains.
