I can say Paleolithic era, and the Neolithic era. They both have something to do with the stone age.
Answer:
Subduction zones are likely to form between converging oceanic and continental plates.

D. To reduce the chance of error.
Doing an experiment multiple times will reduce the likelihood of it having an error.
The work of Rachel Carson and the other ecologists has revealed the terrible consequences of the overuse of DDT. These ecologists worked at the ecosystem level of environmental interaction because they studied the depth of relationships between organisms and their environment.
An ecologist studies environmental problems and determines what causes them and how to improve the situations. In research, they gather data and analyze that for importance. Although, DDT (Dichloro Diphenyl Trichloroethane) was developed or invented as the first of the modern synthetic insecticides in 1940.
Hence, Rachel Carson and other ecologists found that overuse of DDT causes harm to the human liver and reproduction. As a result, humans face symptoms like vomiting, tremors, or shakiness. These problems were affecting the ecology and causing environmental disbalance. So those ecologists were working on the ecosystem level to solve the problem.

Answer:
decreased NADPH production.
decreased sugar production.
Explanation:
The water-splitting complex is associated with PSII and serves as a donor of electrons to the reaction center of PSII. PSII loses its electrons upon trapping of sunlight. These electrons are passed finally to NADP reductase via electron transport chain and PSI. NADP reductase reduces NADP into NADPH. The NADPH formed during the light-dependent phase serves as reducing power in reactions of the Calvin cycle.
A mutation in the water-splitting complex would result in no electron supply to PSII and thereby, reduced production of NADPH. The reduced NADPH production would limit the supply of reducing power for the Calvin cycle and the sugar production would be decreased.
