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>

Answer:
The correct answers are options C, that is, silver tarnishes and becomes black when exposed to oxygen, and option E, that is, diesel fuel burns when it is heated.
Explanation:
Chemical changes refer to the modifications in which the chemistry at molecular level is modified as the initial substance gets transformed into a new and different final substance. This change occurs with the dissociation of old bond and production of new bonds respectively.
I hope this helps. :).
A C - only male expressed the disorder and only females carried the disease. This is typical of a special type of diseases where only females are and can be carriers and only men can and are affected. There aren't many diseases like this but they do exist.
