Photosynthesis is composed of two main parts (light-dependent and light-independent). photosystem i (ps i) and photosystem ii (ps ii) are alike in many ways. how does photosystem i and photosystem ii differ from one another? a) ps i produces glucose while ps ii produces atp. b) ps i occurs in the stroma while ps ii takes place in the thylakoid membranes. c) ps i is a light-independent reaction while ps ii is a light-dependent reaction. d) ps i absorbs the longer wavelength of light while ps ii absorbs a shorter wavelength of light.

Option D

Explanation:

Photosystem I and II differ from each other in following ways –  

a)Light absorbed in PS I has a longer wavelength as compared to light absorbed in PS II. PS I absorbs light of wavelength 700 nm while PS II absorbs wavelength of 680 nm

b)PS I receives electron through the ETC after the PS II completion. While PSII gets its electron form splitting of water.

Hence, option D is correct

answer: tributaries flow into rivers.

wetland is a biome that develops when the water gets accumulated in a land exhibiting a huge depression. these form either seasonally or permanently. the water in the wetland comes from rivers, lakes, ocean, flood, rain or other sources. the wetlands includes mangroves, marshes and peatland.

tributaries flow into the rivers develops a wetland because such water will get deposited in the depression and will restrict the original flow of tributary water. hence, water with low drainage current combines with the river water.
