Bacteria Natural Selection

Answers

Answer 1

Answer:

Bacterial resistance arises through the simple process of natural selection. Bacteria divide rapidly, but DNA replication is imperfect. In the presence of antibiotics, while most bacteria are killed, a small number of resistant mutants may survive and take over.

Explanation:

Answer 2

When bacteria are initially exposed to an antibiotic, those most susceptible to the antibiotic will die quickly, leaving any surviving bacteria to pass on their resistant features

Which ACTN3 genotype (RR, RX, or XX) would provide these Olympic marathon athletes with an advantage, and why?

Answers

Answer:

Explanation:

ACTN3 genotype i.e. XX provides advantage to the Olympic marathon athletes because it strengthens the fiber of the muscles. This gene is also called the gene of speed. This ACTN3 gene has a great influence on the type of fiber that makes body muscles, and they are also linked to strength and endurance so we can conclude that this gene provides benefits to the Olympic marathon athletes by giving strength to the fiber of muscles.

ACTN3 genotype is the gene encoding for the actinin of the skeletal muscle fibres. XX of the ACTN3 genotype will be advantageous for marathon athletes.

What is ACTN3 genotype and XX?

ACTN3 genotype is the gene encoding for the protein of the skeletal muscles fibres that are associated with muscular performance. This protein is expressed in the myofibers with a high twitching ability and result in a high-velocity force.

The XX genotype provides strength to the muscles and is the gene coding for the proteins that give speed. They are also responsible for endurance and are beneficial for athletes.

Therefore, XX of the ACTN3 genotype is advantageous for athletes.
