Answer:
Human blood contains a buffer of carbonic acid (H2CO3) and bicarbonate anion (HCO3-) in order to maintain blood pH between 7.35 and 7.45, as a value higher than 7.8 or lower than 6.8 can lead to death. In this buffer, hydronium and bicarbonate anion are in equilibrium with carbonic acid.
Answer:
Genetic Engineering also known as genetic modification are techniques used to transfer genes from the cells of a donor organism to those of a recipient.
One example is the formation of golden rice. 3 types of genes are added. Two come from daffodils and one from a bacterium, together forming beta-carotene, the chemical which give carrots their colour hence the name 'golden rice'. This is an advantage in LEDCs as beta-carotene is converted to vitamin A, which could save the eyesight of millions of children.
Another example are bananas. The genes that produce antigens to a certain disease are taken and transferred to bananas. The antigens contained in the banana will stimulate an immune response. This has successfully prevented diseases, and it will not be necessary to get needles stuck in you. This can be a very efficient method of preventing diseases in countries that has bananas as their main source of calories.
Gregor Mendel was the "father of modern genetics" and helped disprove the blended theory of inheritance.
