Answer:
The warming of Earth, accompanied by the seas covering the land, created the proper conditions for multicellular organisms to form.
Explanation:
The light dependent reaction produces B NADPH and ATP which are used in the light independent reaction or dark reaction.
Explanation:
Light dependent reaction also called light reaction occur in the thylakoid of grana. Light dependent reaction leads to the generate ATP and NADPH.
Role of ATP
ATP is an energy rich compound which undergo hydrolysis to generate huge amount of free energy. ATP is formed in the cyclic photo phosphorylation by the transport of electron through various electron carrier leading to generate energy for the phosphorylation of ADP into ATP.
Role of NADPH
NADPH act as reducing agent which is formed as the end product of noncyclic photo phosphorylation.NADPH helps in the reduction of Phosphoglyceric acid(PGA) into Phosphoglyceraldehyde(PGALD). The so formed PGALD undergo further reacts to generate glucose and also to regenerate Ribulose bisphosphate(RUBP).
There must be a change in the chemical composition of the substance and the change is highly irreversible
The correct answer is false. Extinction of organisms is not solely cause by man. Even way before, extinction is already happening. It can be caused by natural or human causes. Natural causes includes volcanic eruptions, earthquakes, floods, etc.
Answer:
nucleosomes = 1.65 x 10^6
H2a = 3.3 x 10^6 molecules
H2b = 3.3 x 10^6 molecules
H3 = 3.3 x 10^6 molecules
H4 = 3.3 x 10^6 molecules
Explanation:
It was mentioned in the book Principles of Genetics By D. Peter Snustad, Michael J. Simmons that in the nucleus of <em>D. melanogaster </em>there will be 1.65 x 10^6 nucleosomes and 3.3 x 10^6 molecules of every type of histone i.e. H2a, H2b, H3, and H4 present in it.
