Rather, the Calvin-Benson Cycle is BEGINS when RuBP acquires a carbon from the atmosphere in the form of carbon dioxide to become RuBisCO.
Explanation:
Calvin cycle is the dark phase cycle in plants that generates carbohydrates from reduction of carbon dioxide. The products of light phase – ATPs and NADPH - are used in the Calvin cycle which is a catabolic pathway.
Calvin cycle BEGINS with a RuBP (Ribulose 1,5-bisphosphate) molecule that captures 3 carbon dioxide molecules to become a Rubisco. The Rubisco is hydrolysed into six 3-PGA which are reduced to G3Ps. One G3P is used to make glucose while the others are used to regenerate RuBP.

Answer:
a. The spindle apparatus is present in cells undergoing <u>mitosis and meiosis. </u><u> </u>the spindle is crucial for chromosome sorting.
b. Chromosome replication occurs just prior to <u>mitosis and meiosis I. </u> DNA needs to be copied during S fase to have enough DNA and transfer it to the daughter cells.
c. The cells resulting from <u>mitosis </u>in a haploid cell have a ploidy of n.
Mitosis produces identical cells.
d. The cells resulting from <u>meiosis II </u>in a diploid cell have a ploidy of n. meiosis is the only process that causes chromosome reduction (assuming no errors).
(e). Homologous chromosome pairing regularly occurs during <u>meiosis I.</u> Each daughter cell needs 1 chromosome of each kind
(f). Non-homologous chromosome pairing regularly occurs during <u>none</u>. This is kind of an error.
(g). Physical recombination leading to the production of recombinant progeny classes occurs during <u>Meiosis I </u>
(h). Centromere división occurs during meiosis II and mitosis
(i) Non-sister chromatids are found in the same cell during <u>meiosis II</u>
