Answer:
Dichloroindophenol chemical act as electron acceptor in photosynthesis
Explanation:
DCPIP (2,6-dichlorophenol-indophenol) in general is a dye of blue color which reduces to become colorless and hence act as an electron acceptor in the light reactions of photosynthesis
It is used to measure the rate of photosynthesis, because its reduction leads to identification of reducing agent (Diphenylcarbazide) in plant that is produced at the time of photosynthesis with in the chloroplasts.
Answer:
Molecular evidence
Explanation:
Earlier archaea were considered as bacteria because they show some similarities with bacteria like binary fission as mode of reproduction, lack of a nucleus, etc.
Later Carl Woese separated bacteria in a different domain and divide prokaryote into two domains called bacteria and archaea. He separated archaea from bacteria on molecules evidence.
He compaired rRNA sequence between bacteria and archaea and observed that they both differ in rRNA sequence which allowed him to make a separate domain for archaea.
B, both chemical and biological factors are involved
