Mitosis and meiosis is based off of cells in biology. Mitosis has to do with cells dividing into two identical cells with the same number of chromosomes. On the other hand, meiosis has to do with the parent cell losing half of their chromosomes and dividing twice in order to make four cells.
True - a homogenous mixtures is a mixture that has the same amount of solute.
Answer:
B) a nonsense mutation; this is because a nonsense mutation results in the change of a regular amino acid codon into a stop codon, which ceases translation. This fits with the problem's description of the protein that causes the symptoms as too short, as translation is the process by which proteins/polypeptides are created. A missense mutation would not be the answer because it still codes for an amino acid, which would not shorten the protein. A duplication of the gene would probably just lengthen the protein or not affect its length at all.
Maybe because of global warming and the glacier water melting makING it bigger and deeper. (I hope this is the answer you are looking for)
