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:
B. Theory
Explanation:
A theory can be changed as new information is discovered.
Answer:
Predictions and warnings can also reduce damage and economic losses. When notice of an impending disaster can be issued well in advance, as it can for some riverine floods, wildfires, and hurricanes, property and natural resources can be protected.
Explanation:
Answer:
The central dogma of molecular biology best describes the relationship between proteins and nucleic acid.
Explanation:
Nucleic acid such as DNA is the repository of genetic information in most organism.
The genetic information stored in DNA is Transferred to RNA by transcription which deals with the the production of mRNA from DNA.
The mRNA then undergo translation to transfer its own own genetic information in form of codons to specify amino acids of a protein molecule.
Thus the Central dogma of molecular biology relates proteins and nucleic acids.
