A friend was recently diagnosed with strep throat. One week after his treatment, he redeveloped the infection. In conversation,

your friend tells you, "I must have become immune to the drug the doctor gave me!"
a. Discuss the validity of your friend's statement, providing evidence in support of or refuting his claim.

b. After further conversation, your friend tells you that he stopped taking his initial antibiotics after 2 days because he "felt 100% better." Explain how this action might have played a role in the redevelopment of his infection.

Answer:

<h2>Antibiotic resistance had become very common now a days. People develop antibiotic resistance if they do not take antibiotics according to the prescription by the physician. </h2>

Explanation:

a. Actually the statement given by the friend is absolutely correct. The person has developed a resistance against the antibiotic he had taken to treat the strep throat. The infection has redeveloped and when he had the same antibiotic for strep throat it will become ineffective.

b. This happens because he had stopped taken the complete course of the antibiotic as prescribed by the doctor. If the bacteria changes its shape or removes the effectiveness of the particular antibiotic, resistance develops. The infection has redeveloped may be due to any change in the bacteria or ineffectiveness of the particular drug.

Organisms living in the deep bathypelagic and abyssopelagic zones require oxygen for respiration. What process brings oxygen fro
alekssr [168]

The correct answer is upwelling from equatorial to Polar Regions results in bringing oxygen from the epipelagic zone to deeper oceanic zones.  

It is a process in which the wind mediated motion of nutrient-rich, dense, and cooler water is moved towards the surface substituting the nutrient depleted and warmer surface water. The epipelagic zone refers to the upper layer of the ocean, which is abundant in oxygen and gets the majority of the sunlight for the procedure of photosynthesis. The upwelling of water from the equatorial to the polar region brings oxygen.

A fly has two alleles for the color of its eyes. The green allele is recessive, and is represented by q. The blue allele is domi
murzikaleks [220]

Answer:

p = 0.34

Explanation:

The green allele is recessive, meaning two copies of q (qq) are required to be green. Conversely, animals that are either pp or pq will be blue.

If 44 organisms are green, that means 44 are qq.

For genotype frequencies, the equation is:

homozygous dominant genotype + heterozygous + homozygous recessive = 100%

Which is denoted as

p² + 2pq + q² = 1

We know that q² = 44/100 = 0.44

To work out q, we can do \sqrt{0.44} = 0.66

For allele frequencies, the total must add up to 100%, so

p + q =1

We know that q= 0.66

So p = 0.34, because 0.66 + 0.34 = 1
