Antibiotics can be used to kill the specific pathogenic bacterium, Mycobacterium tuberculosis, that causes tuberculosis. The app

earance of antibiotic-resistant strains has made it more difficult to cure M. tuberculosis infections. These antibiotic-resistant bacteria survive and pass on the genes to their offspring, making the resistant phenotype more common in the population DNA analysis indicates that the genes for antibiotic resistance are not normally present in bacterial chromosomal DNA
Which of the following statements best explains how the genes for antibiotic resistance can be transmitted between bacteria without the exchange of bacterial chromosomal DNA?
a The antibiotic-resistant bacteria release a hormone that signals neighboring bacteria to become resistant
b. The genes for antibiotic resistance are located on a plasmid that can be passed to neighboring bacteria.
c. The antibiotic-resistant bacteria are the result of bacteria that specifically modify their own chromosomal DNA to neutralize the antibiotics
d. The antibiotic alters the bacterial genome of each bacterium, which results in an antibiotic-resistant population

Answer:

c. The antibiotic-resistant bacteria are the result of bacteria that specifically modify their own chromosomal DNA to neutralize the antibiotics

Explanation:

In antibiotic resistant M. tuberculosis bacteria, the M. tuberculosis bacteria become drug resistant due to modification of its chromosomal DNA to the antibiotic due to selective pressure.

Note that selective pressure is an reason for any organism with certain phenotypes to have a survival benefit or disadvantage. This thus leads to natural selection.

This natural selection is what causes the M. tuberculosis bacteria to survive.

Question
son4ous [18]

Answer:

Suppose you have a parent plant with purple flowers and a parent plant with white flowers. Because the b allele is recessive, you know that the white-flowered parent must have the genotype bb. The purple-flowered parent, on the other hand, could have either the BB or the Bb genotype. The Punnett square in Figure below shows this cross.

Why does the biodiversity of an ecosystem affect its resilience
svp [43]

Biodiversity of an why does the biodiversity of an ecosystem affect its resilience because as there are various plants and animals in community, there is high probability that they have developed traits that help them to survive and adapt in their environment.

<h3>What is Biodiversity?</h3>

Biodiversity refer to population of different or various plants and animals living in an ecosystem each performing their roles in their niche.

Therefore, Biodiversity of an why does the biodiversity of an ecosystem affect its resilience because as there are various plants and animals in community, there is high probability that they have developed traits that help them to survive and adapt in their environment.

WHAT ARE SOME FACTS ABOUT TRANSPARENT TRANSLUCENT AND OPAQUIC
Digiron [165]
Transparent means all light can shine through. Common substances that are transparent are clear glass, clean water, and cellophane. Translucent means only some light can filter through the substance. Common translucent substances are tissue paper, the skin of your hand, and lamp shades. Opaque means little to no light passes through the substance. Common opaque substances are denim, cardboard, and leather.

I hope this helps. :)
