D. descriptive investigations

Explanation:

A scientist studying the star Alpha Centauri would probably rely on descriptive investigation to gather data.

In descriptive investigation, experiments cannot be performed since the subjects cannot easily be manipulated or they are far too inaccessible. This form of investigation is based on indirect qualitative investigation of a phenomenon.

  • Alpha Centauri is a distant star several light years away from the vicinity of the scientist.
  • The best way to investigate this distance body is to make inferences from the evidence gathered from observatory stations using telescopes.
  • Astronomers can collect different information and give vivid description of the distant start.
  • It is highly impossible to make comparisons and alter variable in this kind of investigation.

Can someone please help with this and explain! I will mark brainliest!!!

Answer:

D       Flow of protons across an electrochemical gradient

Explanation:

The chloroplast adenosine triphosphate (ATP) synthase uses the electrochemical proton gradient generated by photosynthesis to produce ATP, the energy currency of all cells. Protons conducted through the membrane-embedded Fo motor drive ATP synthesis in the F1 head by rotary catalysis.

In chloroplasts, photosynthetic electron transport generates a proton gradient across the thylakoid membrane which then drives ATP synthesis via ATP synthase.

The light-induced electron transfer in photosynthesis drives protons into the thylakoid lumen. The excess protons flow out of the lumen through ATP synthase to generate ATP in the stroma.

Majority of ATP is produced by OXIDATION PHOSPHORYLATION. The generation of ATP by oxidation phosphorylation differs from the way ATP is produced during glycolysis.

Electrons are passed from one member of the transport chain to another in a series of redox reactions. Energy released in these reactions is captured as a proton gradient, which is then used to make ATP in a process called chemiosmosis.

A model shows that the moon has grown to twice its size, yet it has remained in the same place. In one to two sentences, explain
professor190 [17]

Answer:

If the moon has grown to twice its size, the gravitational force of the Earth on the Moon would be twice as much

Explanation:

The force of gravity between two objects is doubled if the mass of one of the objects is doubled.

If the moon has grown to twice its size, the gravitational force of the Earth on the Moon would be twice as much, since the gravitational force is proportional to the masses of both the Earth and the Moon.
