During photosynthesis, hydrogen ions are most directly used to in the chloroplast pictured above. a) make glucose b) make chlorophyll c) produce carbon dioxide d) drive the production of atp

Option D. drive the production of ATP

Explanation:

Photosynthesis is defined as the process by which plants make their own food in the presence of light.

During the process of photosynthesis, light is trapped in chloroplast (chlorophyll) and at the same time in the presence of light the water molecules split into oxygen, hydrogen ions and free electrons.

The oxidation of water takes place in photosystem II and the hydrogen ions  released in the thylakoid lumen of chlorophyll and contribute to the movement of ions across a semipermeable that results into ATP synthesis.

Hence, the correct option is D.

estuaries are the partially enclosed coastal bodies of brackish water formed at the mouth of sea where river meets an ocean. it is a transition zone between river and sea water so estuaries are influenced to both marine environment such as tides, waves and to riverine such as flow of fresh water and sediments. the mixing of sea and fresh water provide high level of nutrients, making estuaries a high product habitats.

many estuaries suffers degradation from a variety of human activities like erosion from deforestation, overgrazing, overfishing, drainage and eutrophication.

so from the above statement answers will be

1. false as estuaries are formed due to both brackish and freshwater.

2.true, due to high productivity estuaries are breeding ground for many marine species.

3. direct and indirect activities of man that contribute to pollution and deposition of sediments.
