A scientist is using a species of green algae to study electron transport chain in photosynthesis. He uses a laser to inactivate all of chlorophyll A in the algae, but leaves chlorophyll B intact (case 1). In a separate experiment, the scientist applies a chemical to the algae that inhibits PS I but does not affect PS II (case 2).

The scientist done wrong by inactivating chlorophyll A and PS I.

Explanation:

The scientist done wrong by inactivate chlorophyll A and PS I. If he wants to study electron transport chain in photosynthesis, he needs chlorophyll A and PS I for that because the central role of chlorophyll A is to donate electron in the electron transport chain while on the other hand, the primary function of the photosystem I is the NADPH synthesis, where it receives the electrons for PS II.

explanation:

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.
