Answer: Option A. thylakoid membrane

Explanation:

Photosynthesis is the process that occurs in two sequential stages light dependent reaction ans light-independent reaction.

The H+ ion (Proton)  gradient forms during photophosphorylation where cytochrome b6f and ATP synthase work together to produce ATP.

In non-cyclic photophosphorylation, the electrons produced from PS 2 pumps H+ ions from the stroma to the lumen that makes the proton gradient across the thylakoid membrane. this proton gradient is allowed to form a  proton-motive force that is used by ATP synthase to produce ATP.

In cyclic photophosphorylation, the energy of electrons from PS2 and PS1 are used by cytochrome b6f uses to create ATP and to restricts the production of NADPH.

Hence, the correct option is A.

Which of the following descriptions about RNA is not correct?
gayaneshka [121]

Answer:

The correct answer is option a. "Double-stranded regions of RNA typically take on an B-form right-handed helix".

Explanation:

Most of the native double-stranded DNA is on an B-form right-handed helix, following the structure proposed by Watson and Crick with about 10–10.5 base pairs per turn. However, double-stranded RNA does not follow this structure, and most regions have an A-form structure. The A-form right-handed helix have slightly more base pairs per turn, which makes it 20-25% shorter than B-DNA.

Divergent faults form when tectonic plates _____. move away from one another stop moving crash into one another slide past each
AleksAgata [21]

Correct answer: A). Move away from one another

The divergent boundaries are formed when the tectonic plate move away from each other. It forms volcanic islands that occur when the plates move away in order to produce gaps that are filled by molten lava.

The divergent boundary contributes to the formation of seafloor spreading. When the plates that are made up of oceanic crust move away from each other, a crack in the ocean floor appears. Then the magma oozes out from the mantle to fill that crack that results in ocean ridges.

Hence, the correct answer would be option A.

What would happen if Jupiter's gravitational pull increased
kirill115 [55]

Answer:

The amount of mass that planet Jupiter has in the solar system makes it approximately five times larger than all other planets in it. As Jupiter’s gravity pulled on another planet tightly, its diameter grew and it expanded. The density and gravity continued to increase, resulting in even more planet compression.
