Answer:

Paul has natural active immunity, while Nicholas has artificial active immunity.

Explanation:

Natural active immunity is an immunity that occurs when an individual is exposed to a disease causing organism, gets infected, and also become immune to the disease due to the primary immune response. From the question, Paul has natural active immunity because he had chicken pox before, and the virus that causes chicken pox has interacted with his immune response, hence, making him to develop natural immunity to the disease.

Artificial active immunity is an immunity that an individual acquires when small amount of immunity to a disease is deliberately exposed to his body. Artificial active immunity is usually produced in the form of vaccinations. From the question, Nicholas has artificial active immunity because chicken pox vaccines were intentionally introduced to his body.

slamgirl [31]

Answer:

This is antibiotic resistance. It occurs with over use of antibiotics.

When antibiotics are over used, likely targeted bacteria are being   killed constantly even in absence of an infection. However,  few  bacteria may resist the antibiotics effects(selective pressure) , and therefore survived. If these resistant bacteria who were able to survive the selective pressure  reproduce, they pass the resistant trait/ gene into their offspring.

Therefore with continuous exposure to antibiotics, they will  resist the antibiotics effects(selective pressure),and thus reducing the effectiveness  of antibiotic treatments  with subsequent application.

11Alexandr11 [23.1K]

Answer:

Cystic fibrosis (CF) is more common in Caucasian individuals and is inherited with an autosomal recessive inheritance pattern.

Explanation:

Cystic fibrosis (CF) is a condition of genetic origin, which affects organs such as the lungs, pancreas, intestine and liver. CF is characterized by the production of very thick and viscous mucus, and promotes the formation of cysts and fibrosis of the affected organs.

CF is an inherited disease that is transmitted in an autosomal recessive pattern, that is, the altered gene is required to be on both chromosomes of the allelic pair, in order to be expressed.

It is a very common disease in Caucasian individuals, especially those of European descent.
