Answer:
The hemoglobin molecule has four binding sites for oxygen molecules: the iron atoms in the four heme groups. Thus, each Hb tetramer can bind four oxygen molecules.

The genetic characteristic of two different organisms are induced into a new host organism for the purpose of producing new genes.
<u>Explanation:</u>
In the field of bio technology, Recombinant DNA technology plays a very important role. This helps in the production of genes. The first thing insulin of human was produced with this technology. In this technology, the gene that is to be produced is cut and it is placed inside a host organism where it gets multiplied.
This technology uses five steps in gene production. Firstly, the DNA that is essential will be cut. this is done by restriction site. PCR is used secondly in order to amplify the copies of the genes. Then these are induced into Vectors after which they will again be introduced into a host organism. Then finally the results will be the genes of the desired characteristics.
Answer:
The correct answer is: (B) erythropoietin (EPO) – increases white blood cell production.
Explanation:
Erythropoietin is a hormone secreted by the kidney when dealing to cellular hypoxia (low oxygen content on body tissues) to stimulate red blood cell production. This is because red blood cells are the ones that transport oxygen to every tissue in the body.
<u>Answer:
</u>
