In the light dependent reactions light energy is absorbed by the photosytem II and an electron is released. This electron causes a process called photolysis to occur(H20-->2H++2e-+1/2O2). This is how O2 is released in the atmosphere. The electrons resulted from photolyisis enter the electron transport chain. In the electron transport chain using the energy in the elecrtons, hydrogen protons are pumped inside the thylakoid. Those protons accumulate to form an electrochemical gradient. That means the protons need to flow out, and they do through an enzyme called ATP-synthase which turns ADP and inorganic phosphate into ATP and water. In the electron transport chain, the electrons reach Photosystem I where NADP+ is reduced and becomes NADPH.
ATP and NADPH store the energy absorbed in the light dependent reactions. Those two molecules are needed when CO2 is fixated in Calvin's cycle to synthesize glucose.
Very high level atmosphere
Answer:
all of the above
Explanation:
All the statements are true that is Sweating is an example of positive feedback because when you sweat your body becomes hot and your inner body becomes cool. Shivering is an example of negative feedback because shivering occurs when there is cold in the body and can lead to sickness. The nervous system is responsible for sensing changes in the environment because it is responsible for sensing what's going on in our body.
Answer:
Dune vegetation would miss a significant source of nutrients if sea turtles go extinct and would not be as stable and not large enough to support the dunes, resulting in increased erosion.
Explanation:
While their range is wide, due to extensive egg collecting and bycatch fisheries, the numbers of leatherback turtles have decreased dramatically over the past century.
