b) ii, iii, and iv
c) i, iv, v, and vi
d) i, ii, iii, and v

A)I, V, and VI

Explanation:

In a nutshell, photosynthesis is an important phenomenon for autotrophs like plants where they synthesize their own food (glucose) from inorganic source (CO2) using energy from sunlight. However, the photosynthetic process consists of more complex reactions that encompasses two stages: light-dependent and light-independent stage.

For the purpose of this question, the light independent stage is so called because it does not require light to occur i.e. can take place in the dark. It is also called CALVIN CYCLE and it occurs in the matrix of the CHLOROPLAST called STROMA. In the Calvin cycle, CO2 absorbed by plant via their stomata is fixed by RUBP (CO2 acceptor) and catalyzed by RUBISCO.

This fixation, coupled with series of reduction and phosphorylation by NADPH and ATP respectively (produced during light dependent stage), produces a 3 carbon compound called Glyceraldehyde-3-phosphate (G3P), which leaves the Calvin cycle to contribute to the formation of Glucose.

the correct answer is - d. china has a large and growing population.

the fact that china has a large (the biggest) population, and it is still growing, doesn't hinder the agriculture production in the country. in fact, it can for increased production in the agriculture, since there's more labor force, as well the sheer mass of people produces lots of scientists that come up with new inventions as to how to improve this sector. nice example is the inner mongolia region in china, in general dominated by the gobi desert, but few scientist came up with a nice idea as to how to make the region productive by using plants that are very resistant to droughts, so lots of people have been employed, and the region is becoming greener and greener each year, and the production of food in this region is also increasing.
