Answer:

C). Seafloor spreading.

Explanation:

Paleomagnetism is characterized as the 'study of the account of direction and strength of magnetic fields of the Earth in sediments, rocks, etc.' The hypothesis that was authenticated by using this study would be 'seafloor spreading' by displaying that magnetic reversal as strips of rotating polarity in gradually disseminating seafloor. This description of magnetic stripping by employing paleo-magnetism made the scientists believe that alternate crusts are being frequently made under ocean/sea. Thus, <u>option C</u> is the correct answer.

Which molecule is the final electron acceptor for electrons from photosystem I? a. Oxygen b. Chlorophyll in photosystem II c. Ca
Mumz [18]

The molecule which is the final electron acceptor for electrons from photosystem I is (d) NADP⁺.

Photosystem I is the protein complex involved in the process of photosynthesis. It captures the light energy to mediate the transfer of electrons from a series of electron transporters. It is involved in non-cyclic as well as cyclic photophosphorylation.

NADP⁺ is the Nicotinamide Adenine Dinucleotide Phosphate. It acts as a coenzyme. It is an important constituent in various anabolic reactions like Calvin cycle, lipid and nucleic acid syntheses, etc. The oxidized form of NADP⁺ is NADPH. It is present in organisms of almost all kinds.
