Which statement about the light-independent reactions in photosynthesis is true?
they occur in the thylakoids.
they produce atp and nadph.
they release oxygen as waste.
they comprise the calvin cycle.

The correct answer is They comprise the Calvin cycle.

Photosynthesis is a process by which green plants synthesize their own food from CO₂ and H₂O in the presence of sunlight. It is divided into light dependent and light independent phase.

Light dependent reactions occur in the thylakoids of chloroplast. In this, ATP and NADPH are produced ( using energy from sunlight and water) and Oxygen is released in the atmosphere.

Light dependent reactions occur in the stroma of the chloroplast. It is also called as Calvin cycle. During this, plants use ATP and CO₂ and produce sugar ( like glucose).

Thus, the statement which is true about light-independent reactions in photosynthesis is- They comprise the Calvin cycle.

the answer is d-They comprise the Calvin cycle.Explanation:

the three components of a nucleotide are the nitrogenous base, the phosphate group and the five-carbon sugar.

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.
