<span>Sixty percent of daily energy for the human body is determined by basal metabolism rate, or BMR. Basal metabolism rate is the minimum energy needed for a body to function (i.e. how many calories you would burn resting for an entire day and night).</span>
Water enters the atmosphere through transpiration (from water of plants, giving off water vapor from pores of leaves), and evaporation (heated water changes into water vapor and rises into the atmosphere).
Remember to search the water cycle online, look at pictures, and do a bit of studying on your own. This will help you understand the water cycle to the next level.
I hope this helped!
Chemical energy is used to pump protons through a proton pump, creating a high concentration of protons ( H+ ) inside the thylakoid disk. ATPase has a channel that allows for the facilitated diffusion of protons back in through the membrane. this activates ATPase, which in turn catalyzes the formation of ATP.
