<u>Antibiotics are used to kill bacteria:</u>

Antibiotic is a naturally produced substance that is used to kill bacteria. The first antibiotic was penicillin produced from fungus. The word antibiotic means against life which means it is against the life of pathogenic bacteria.

In the case of the living organism that is treated antibiotic is ‘pro life’. Antimicrobials are used to kill pathogenic microbes like fungus, bacteria, virus etc. Sometimes the microbes become resistant to the antimicrobials and they are said to develop is antimicrobial resistance.

When pathogens develop antimicrobial resistance newer drugs have to be developed in place of the earlier ones to treat the disease.

Explain how breast-cancer genes are still present in the population, despite cancer-related surgeries and deaths.

Rus_ich [418]

Answer:

What are so called breast-cancer genes, are mutations in two genes: BRCA1 (BReast CAncer gene one) and BRCA2 (BReast CAncer gene two), and are also associated with ovaric cancer. According to the question, these genes are present in the popolation despite surgeries and deaths, and asks why. Surgeries does not eliminate the genes, they eliminate the tumors, and people can still reproduce after that. And also, most people already had offspring before they know they have cancer, so they are inheriting the mutations on the genes anyway.

Fur color in animals is frequently controlled by more than one gene. However, brown fur in rabbits is dominant over white fur. A

vodka [1.7K]

Answer:

Please find how this is possible in the explanation below

Explanation:

This question is regarding a gene in rabbit coding for fur color. Brown fur (B) in rabbits is dominant over white fur (b). However, according to the question, a white female gives birth to all white rabbits, even though the father had brown fur. This is possible because the father is heterozygous for the brown fur i.e Bb.

Hence, in a cross between a heterozygous father (Bb) and a white mother (bb), the following gametes will be produced by the following parent:

Bb - B and b

bb - b and b

Using these gametes in a punnet square (see attached image), the probability of 1/2 of the offsprings will possess white fur (bb). Based on this result, the white female is able to give birth to all white rabbits because the male rabbit contributed the white allele (b).
