The table below describes three different regions of an ocean ecosystem. Zone
Description
Zone 1 Air, sun, and water exposure; crashing waves.
Zone 2 Water depth less than 200 meters; lots of
sunlight; relatively warm water.
Zone 3 Very deep water; no light; cold except near the
thermal vents that emit heat and chemicals.
Based on table, which of the following is a valid conclusion?
A. There are no producers in Zone 3 that rely on photosynthesis.
B. Organisms in Zone 1 must be able to withstand very cold water.
C. Organisms in Zone 3 must be able to tolerate occasional air exposure
D. The warm water and abundant sunlight in Zone 2 limits the plankton population

what statement best describes the difference between the sympathetic and parasympathetic nervous systems?

the sympathetic nervous system prepares the body for intense physical activity and is often referred to as the fight-or-flight response. the parasympathetic nervous system has almost the exact opposite effect and relaxes the body and inhibits or slows many high energy functions.

i believe it is c: genes for body color and wing size are inherited separately from each parent.

these muscles maintain the blood pressure in the vessels. the smooth muscles are innervated by nerves of the autonomic nervous system. when the muscles contract, they cause vasoconstriction of the vessels and increase blood pressure. when the muscles relax, they enable vasodilation of the   blood vessels hence reduce blood pressure.
