Conjugation is a very effective process for spreading antibiotic resistance among diverse bacterial populations such as those fo

und in the mammalian gut. Which statement best explains this observation?
A) Conjugative plasmids can be transferred to a bacteriophage.
B) Two different species of bacteria can share DNA, including antibiotic-resistance genes, during conjugation.
C) Conjugation is the only source of genetic variation in bacterial cells.
D) Conjugative plasmids cause a bacterial cell to reproduce more quickly, which increases the rate of evolution and the appearance of antibiotic resistance.

Answer:

B) Two different species of bacteria can share DNA, including antibiotic-resistance genes, during conjugation.

Explanation:

Conjugation is a process by which bacteria can exchange their genetic material between them. So through conjugation, the antibiotic-resistant gene coded by plasmid can be transferred through sex pilus to another bacteria.

So due to conjugation two different species of bacteria can share DNA which can include antibiotic-resistant genes. Therefore, through conjugation genetic variation and evolution are favored in bacteria. So due to this reason conjugation is a very important process in bacteria to spread antibiotic-resistant genes.

zhuklara [117]

Answer:

The population has evolved because there was a change in allele frequencies.

Explanation:

The evolution may be defined as the process of the change of the species characteristics with the passage of the time. The natural selection, mutation and the genetic drift might cause the evolution.

The population might have evolved as the allele frequencies has changed from the generation to the generation. Although the variation among the population is quite less but the variation is still enough for the evolution of the elephant seals.

Thus, the correct answer is option (D).
