Which best part of the automatic system is most likely to be a dominant while someone is napping after lunch? a. the perpipheral nervous system b. the sympathetic nervous system c. the somatic nervous system d. the parasympathetic nervous system

B. The sympathetic nervous system

During sleep the sympathetic nervous system, the body fight-or-flight system relaxes, and blood pressure falls, muscles relax and skin vessels dilate, warming the body. Like other parts of the nervous system, the sympathetic nervous system operates through a series of interconnected neurons.  

Answer is active transport. Plants use active transport during the ion uptake.

Explanation:

In the process of active transport, substances are moved from an area where they are in lower concentration to a region where they are in higher concentration (against a concentration gradient). The concentration of minerals like magnesium ions is higher in the root-hair cells of plants than in the soil. So the plants take in the ions they need from the soil by the active transport across the root hair cells. This process requires energy which is supplied in the form of ATP (adenosine triphosphate).
