I would say "B', as polar bears don't actually have to get in water at all!
Answer:
a. The electrons provide energy for the H+ pump to transport more H+ ions into the thylakoid space.
d. The photolysis of water releases H+ ions into the thylakoid space.
Explanation:
This question describes the first stage of photosynthesis, which is LIGHT-DEPENDENT REACTION. The light dependent reactions involve creating ATP (energy carrier) and NADPH (electron carrier) needed for the Calvin cycle (light independent stage) to occur.
The ATP is formed by pumping hydrogen ions (H+) into the thylakoid space/lumen, hence, creating a electrochemical gradient needed for ATP synthase to synthesize ATP. The buildup of H+ ions is caused by:
- The electrons that arise when light photons hit a chlorophyll molecule is used to provide energy for the H+ pump to transport more H+ ions into the thylakoid space.
- The photolysis of water results in the production of electrons (e-) and hydrogen ions (H+). These hydrogen ions are released into the thylakoid space.
They are genetically identical or clones. There is no genes, no genetic variation.
Hope that helps! c:
Life does exist in the Mariana Trench, even at its deepest spots. The organisms living here are mostly a wide variety amphipods, sea cucumbers, sea anemones, etc. These organisms survive mostly by feeding off of the dead living beings on the upper layers of the Trench, which fall down to the depths as a result of gravity.
Be a cell hope this helps
