During the light-independent reaction, carbon dioxide is fixed by adding it to a 3-carbon compound
Answer: Option B
<u>Explanation:</u>
In the first stage of ''Calvin cycle'', light independent reactions are started and the carbon dioxide gets fixed from a molecule that does not have light to a molecule having light and in the second stage where carbon compound like ATP and NADPH gets reduced into a three carbon compound. This is done for converting energy in to a chemical bond energy for example in a glucose.
Answer:
Hydrogen in the core of the star is converted to helium by nuclear fusion. When the hydrogen supply in the core begins to run out, and the star is no longer generating heat by fusion, the core becomes unstable and contracts.
