One reason is for safety! in case you get stranded in a body of water you can keep yourself afloat
Answer:
D
Explanation:
I am working on that kind of stuff right now
Answer:
Photosystem I (PS-I )and photosystem II (PS-II ) are two multi-protein complexes. These complexes contain the pigments used to absorb, harvest and catalyze the photons and light energy in the photosynthetic reactions. The main purpose of photosynthesis reactions to produce high chemical energy compounds.
Photosystem I and II are different from each other because of their absorbing wavelength of light. PS-I absorbs the longer wavelength of light than PS-II.
PS-I plays the major role in the production of high energy carriers ATP and NADPH using light energy (700 nm).
PS-II plays its function in the hydrolysis of water and ATP synthesis using light energy (680 nm).
A. Potential energy to Kinetic energy.
It becomes Kinetic energy by rolling down the hill thanks to gravity and friction.
