Natural selection happens naturally in nature and selective breeding is humans deciding what traits they want repeated in their animals.
Bacteria. As I remember I’m sure it’s bacteria
Here’s what I found that may help:)
Answer:
Cyclic electron flow
Explanation:
→The objective of this process is to synthesize ATP, so that proportion of ATP and NADPH could be met
→to prevent photo-inhibition of PS 1 and 11.
It involved only Photosystem 1 .(PS1) The process begins with the photo activation of chlorophyll molecule. <u>The excited electrons at higher energy levels, emitted from the chlorophyll molecule is captured by electron acceptors and return to the chlorophyll molecule ( rather than the usual PS) by chains of electron carriers . </u>
Therefore these electrons did not lose their energy as thermal energy. Instead large quantity of energy is conserved for ATP synthesis , via chemosomosisWith the resultant ATPs used in Calvin cycle for glucose, Amino acids and fatty acid production in light independent stage.
T<u>he continuous cyclic flow of these electron carriers(instead of non -cyclc flow or non cyclic photophosphorylation) ensures large quantity of energy conservation for the production of ATPs in chemosomosis.</u>
This explains the reasons for 30,000 molecules of ATPs consumed.
NREM-1, NREM-2, NREM-3, REM are the four in order stages of sleep. During NREM-3 stage there’s large, slow delta waves, hard to awaken, sleep terrors, sleepwalking, some nightmares and bed-wetting is most likely to occur at the end of this stage. This stage normally begins about 35-45 minutes after being unconscious.
