Answer:

Antigenic variation is the change occurs in antigenic property of the pathogen. In antigenic variation, a pathogen does changes in its surface protein or carbohydrate so that the immune system of the host is not able to recognize the pathogen.  

This antigenic variation is very much beneficial to pathogens because it gives advantage to the pathogen to infect the host again and again without being recognized by immune cells and to increase in number.

A recombination of avian and human influenza virus in a host like pig created a new version of the influenza virus which became very endemic worldwide is a classic example of antigenic shift. M. tuberculosis evades immune response by doing antigenic shift it's membrane and cause tuberculosis.

Olegator [25]

Explanation:

Lucille's cells need oxygen. In order for cells to properly function, they need to be oxidized. If Lucille's respiratory system is not working then her body cannot receive the oxygen that it needs in order to send to her blood cells. The circulatory system pumps Lucilles's blood around her body but if there is no oxygen, Lucille's cells/heart cannot properly function, this making it difficult for her to play soccer.

The locus B on the X chromosome of a malaria-carrying mosquito shows a 49% recombination rate with respect to the locus M. Since
Free_Kalibri [48]

Answer:

The correct answer is - P = 0.45

Explanation:

The Chi-square test is a test that determines the assorted genes independently. Here p-values used to make conclusions in significance testing.

If the p value is less than the significance level we expect or choose, then this null hypothesis is rejected in favor of the alternative hypothesis. It p value is greater than or equal to the significance level, then we fail to reject the null hypothesis.

So in this case, as the recombination rate is 49% so the p value which satisfies the conclusion will be around 0.45 and values near to it.
