I'd appreciate if you attached the article as well. But i'm 90% sure it's option D. A quick search reveals that it was dubbed Black Saturday due to rapid fire growth within Yellowstone park. Option D is really the only one that relates to that at all.
Hope this helps!
Answer:
Interphase is the part of the cell cycle that is not observable by naked eyes. During interphase, the cell grows (G1), replicates its DNA (S) and prepares for mitosis (G2). A common misconception is that interphase is the first stage of mitosis, but since mitosis is the division of the nucleus, prophase is actually the first stage. In interphase, the cell gets itself ready for mitosis or meiosis.

Answer:
A) identify the N-terminal amino acid of a polypeptide
Explanation:
Edman degradation is a series of chemical reactions that enables the stepwise cleavage of the amino-terminal residue from a peptide/protein. This method sequentially removes N-terminal residues without disrupting peptide bonds between other amino acid residues, thereby obtaining the amino acid sequences from the target peptide/protein. Edman degradation can be defined as a cyclic method in which each residue is cleaved off from the amino-terminal end of the peptide/protein and then identified by reverse-phase chromatography, which is a technique used to separate peptides/proteins on the basis of their hydrophobicity.
Each human has two parents. The gamete from each parent is a cell resulted by meiosis, so it has half the number of chromosomes present in a somatic cell, 46/2=23 chromosomes.
