17. What does EPO do? a. stimulates RBCs to release stored O2 b. stimulates RBC production c. increases the number of heme groups per molecule of hemoglobin d. increases ventilation rate. e. b and c

the correct answer is B

Explanation:

Erythropoietin (EPO) is a glycoprotein hormone whose main function, which is not unique, is the regulation of the production of red blood cells and with it all the processes related to the formation of energy by aerobic route

It is made by the kidney.

1) gene flow

- it is described as the transfer of genes from one population to another population so that frequency of gene is increased.

-a zebra migrates to join a different herd of zebras.

2) natural selection

- a mechanism of evolutionary change in which individuals with advantageous traits survive and reproduce whereas the others ( those that can not adapt) eliminate from the population.

-competition for sunlight leads to taller trees.

3) mutation

- permanent change in the nucleotide sequence of dna ( genetic material) that could have harmful or useful consequences.

-the dna of a snake changes to make its venom stronger.

4) genetic drift - it is a random phenomenon ( that occurs by chance such as fire) that results in change in the gene frequency in a small population.    

-a grassfire randomly sweeps through a population of buffalo and kills most of the animals.

explanation:

the answer is d (apex) good luck : ))
