I snatched this from someone else, so it isn't mine, but I hope it helps. They don't have a username so I cannot credit them.
Explanation:
DNA content is halved in both meiosis I and meiosis II. Ploidy level changes from diploid to haploid in meiosis I, and remains haploid in meiosis II.
During anaphase of both meiosis I and meiosis II, the DNA content (number of copies of chromosomes) in a cell is halved. However, the ploidy level changes only when the number of unique chromosome sets in the cell changes. This occurs only in meiosis I (where separation of homologous chromosomes decreases the ploidy level from 2n to n and produces daughter cells with a single chromosome set).
<span>Although salmonella typhi is known to be a disease caused by the ingestion of infected fecal matter, that fecal matter is often found on food items because of improper hygiene on the part of field workers harvesting crops which are then possible eaten raw. Also it can be passed on by food handlers in restaurants practicing improper bathroom hygiene. But it has been known to be carried in shellfish that were exposed to sewage in the water. So if you had to name a specific food that would be shellfish.</span>
Answer: The correct option is 
Explanation:
According to the Bronsted Lowry conjugate acid-base pair, an acid is a substance that donates protons and a base is a substance that accepts protons.
From the given options, represents a Brønsted Lowry base as it is accepting 
and 
represents a Brønsted Lowry acid as it is donating .
