one controls thinking, the other controls feeling

each belongs to a different nervous system

one is inherited, the other is learned

one controls voluntary activity, one controls involuntary activity
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.

5

Atoms of an element whose atoms can vary in the number of neutrons in their nucleus are called which of the following?

64% Answer Correctly

products

reactants

isotopes

ions
Solution

The atomic mass of an element listed in the Periodic Table represents the average mass of a single atom of that element and is measured in atomic mass units (amu). This number is an average as some elements have isotopes with atoms that vary in their number of neturons and, therefore, differ in weight.
