What are some examples of negative feedback?
select all that apply.
cells increasing their activity to produce more heat when it is cold.
the kidneys reducing the water level in the body when a person drinks a lot of fluids.
pupils getting smaller to reduce the amount of light reaching the eye when the light is very bright.
the body produces a protein. in turn, the protein triggers the body to make more of the protein

Thermoregulation (if body temperature changes, mechanisms are induced to restore normal levels)

Explanation:

the overall balanced equation

6co2 + 6h2o > c6h12o6 + 6o2

sunlight energy

where: co2 = carbon dioxide

h2o = water

light energy is required

c6h12o6 = glucose

o2 = oxygen

correct answer is option a.

tropopause, stratopause and mesopause have all in common aspect that is point of maximum temperature in its layer of the atmosphere. all layers of atmosphere observe abrupt change in temperature. tropopause is the boundary between troposphere and stratosphere. stratopause is the boundary between stratosphere and mesosphere. mesopause is the boundary between mesosphere and thermosphere. these all boundaries are ranges between altitude of 0 to 80 km.
