What is a major difference between the somatic and autonomic nervous systems?

one controls voluntary activity, one controls involuntary activity

one controls thinking, the other controls feeling

one is inherited, the other is learned

each belongs to a different nervous system
Solution

Both are part of the peripheral nervous system. The somatic nervous system sends sensory information to the central nervous system and controls voluntary actions while the autonomic nervous system regulates involuntary activity in the heart, stomach, and intestines.

2

3

During the water cycle, water enters the atmosphere as a gas through which process?

26% Answer Correctly

evaporation

precipitation

both evaporation and transpiration

transpiration
Solution

The water (hydrologic) cycle describes the movement of water from Earth through the atmosphere and back to Earth. The cycle starts when water evaporates into a gas from bodies of water like rivers, lakes and oceans or transpirates from the leaves of plants.

4

A dominant trait will be expressed when paired with:

74% Answer Correctly

a chromosome

a gene

a dominant trait

a recessive trait
Solution

The traits represented by genes are inherited independently of each other  (one from the male and one from the female gamete) and a trait can be dominant or recessive.  A dominant trait will be expressed when paired with a recessive trait while two copies of a recessive trait (one from each parent) must be present for the recessive trait to be expressed.

5

What part of the nervous system is responsible for controlling involuntary actions like breathing, swallowing, and heartbeat?

63% Answer Correctly

spinal cord

cerebellum

cerebrum
