What is the best example of how the nervous system maintains homeostasis a. the parasympathetic system counteracts the sympathetic system. b. the spinal cord returns the body to homeostasis after the brain reacts. c. the peripheral nervous system conteracts the central nervous system d. the brain prevents the reflex arc from happening in the body

A

Explanation:

A. The parasympathetic system counteracts the sympathetic system.

Explanation:

Homeostasis refers to the tendency of organisms to maintain the steady state, that is, to maintain the constant internal environment.  The parasympathetic division of autonomous nervous system serves to control the internal organs of body and maintains the resting state by conservation or restoration of energy. The sympathetic division serves to mobilize the energy during emergency conditions and prepares the body for fight and flight conditions. Hence, antagonistic effects of these two divisions maintain an internal body balance.

1: most common garden plants prefer loam — soils with a balance of different-sized mineral particles (approximately 40% sand, 40% silt, and 20% clay) with ample organic matter and pore space. however, some plants grow better in sandy soils, while others are well-adapted to clay soils.

2: available water capacity is the maximum amount of plant available water a soil can provide. it is an indicator of a soil's ability to retain water and make it sufficiently available for plant use. available water capacity is the water held in soil between its field capacity and permanent wilting point.

3: it is the same for all living things (plants and animals). it also includes very tiny organisms that our eyes cannot see. they are known as microorganisms, and include viruses, bacteria and fungi.
