Some humans have genes that make them resistant to infection by HIV. Would human populations likely evolve differently in areas of the world where HIV infection rates are high?

Answers

Answer 1

Answer:

Answer:

Yes, the population can evolve differently with resistance gene to the HIV

Explanation:

AIDS is a deadly disease caused by the Human immunodeficiency virus. The HIV infection ultimately results in the death of the host and the cases are increasing every year.

If in the population of the area affected with the HIV AIDS develop some resistant gene to the disease, therefore, the resistant gene will be passed on to the generation and the population will evolve differently as a measure or response of adaptation and natural selection.

The case of sickle cell anaemia with modified shapes of red blood cell in the population of Africa, a resistance mechanism to malaria can act as evidence to the HIV case.

Thus, Yes, the population can evolve differently with resistance gene to HIV is the correct answer.

When succession occurs after a disaster, like a wild fire, it is called secondary succession.FALSE - it is called fire succession
FALSE - it is called primary succession
FALSE- it is called tertiary succession
TRUE

Answers

True, when succession occurs after a disaster, like a wild fire, its called secondary succession.

Secondary succession occurs when an existing population has been reduced due to a fire. So that it occurs on soil that was already present prior to the disaster.

When Mendel crossed true-breeding pea plants that have inflated pods (PP) with those that have constricted pods (pp), it was observed that F1 offspring had a genotype of Pp. What would their phenotype be?

Answers

So the question is all about breeding two inflated pods. So the best answer would be this one:
F1 has Pp genotype. It is heterozygous. If you have a dominant allele, you will get the 'dominant' phenotype no matter what you have on the other allele. Usually people use upper case letter as dominant allele and lower case letter as recessive allele. So, in this case P is inflated and p is constricted. The F1 phenotype is inflated pods.

If secretory proteins are isolated from secretory vesicles and injected into the cytosol, they will A. remain in the cytosol until they are degraded. B. be secreted through channels in the plasma membrane. C. be taken up into the rough ER and follow the secretory pathway. D. be taken up into secretory vesicles and secreted.

Answers

Answer: Option C

Explanation:

The secretory proteins are found inside the cell which is secreted by the Endoplasmic reticulum and moves from the same route towards the Golgi apparatus.

Although it is secreted from the endoplasmic reticulum of the cell, but if it is injected from the outside to the inside of the cell then it moves to the rough endoplasmic reticulum and follows the secretory pathway of the cell.

Hence, the correct answer is option C
