B. The new cells would have an incorrect number of chromosomes.
Answer:
1. The bacterium Vibrio cholerae obtains genes from its prey, a genetic transfer that occurs through the mechanism of transformation (option d).
2. In the V. cholerae bacterium, the acquisition of new genetic material involves the production of temporary merodiploid cells between the time the genetic material enters the cell and the time when recombination occurs (option a).
Explanation:
1. In pathogenic bacteria such as Vibrio cholerae the introduction of genetic material into their genome produces structural and functional changes that promote their ability to cause disease.
In this case, the incorporation of genes by transformation leads to morphological change, development of colonization factors and strengthening of the toxin that V. cholerae produces.
2. Bacteria are prokaryotic cells whose chromosome charge is haploid, with the ability to have a single allele in the gene that determines a trait, and not in allele pairs, as is the case in eukaryotic cells.
The addition of external genetic material results in the bacterium having two alleles for a gene at any given time, which is called a partial diploid or merodiploid cell.
<u>Once V. cholerae acquires new genetic material it becomes a merodiploid cell while genetic recombination occurs</u>.

Based on the lab results, Candida albicans are most likely causing Tori's new symptoms. Candida albicans is an opportunistic fungus that is the cause of Candida related complex and many undesirable symptoms including fatigue, weight gain, joint pain, and a gas. The Candida albicans yeast is a normal part of your gut flora, a group of microorganisms that live in your digestive tract.
Answer:
e: pleiotropy
Explanation:
<em>Pleiotropy is a genetic term that describes a situation in which a single gene controls the expression of multiple traits. </em>
Depending on the underlining mechanism, there are different types of pleiotropy:
- gene pleiotropy: this occur when a protein representing a gene interacts with other proteins or catalyses multiple reactions
- developmental pleiotropy: this occur when mutation of a gene have multiple phenotypic effects
- selectional pleiotropy: This occur when the phenotypic expression of a single gene has multiple effects on fitness.
In this case, cystic fibrosis gene has multiple phenotypic effects which include its effects on the lungs, pancreas, digestive system and other organs.
<em>The correct option is e.</em>
