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>.
Answer:
Neural: faster and shorter in duration
Endocrine: slower and longer in duration
Explanation:
The nervous system is responsible for transmitting nerve impulses through the molecules that manufacture and secrete neurons, called neurotransmitters. This information is transmitted through the nervous way
The responses of the nervous system are fast, brief and very specific, associated with responses of movement and sensory perception
The endocrine system is characterized because it controls its functions through chemicals called hormones. It is responsible for very diverse functions, associated with metabolism and growth.
These responses tend to be slower than those of the nervous system but of longer duration, since it comprises functions that are regulated slowly.
