Of human genome codes for protein? 1 percent
<span>Positive Rh factor represents the presence of the rhesus protein on the blood cells.</span> <span>Rh factor or Rhesus factor is used to describe the presence of antigen Rh (D) in the blood. A person who is, for example, AB Positive (AB+) has the A and B antigens and the Rh(D) antigen, whereas someone who is AB Negative (ab-) lacks the Rh(D) antigen. Antibodies to Rh antigens can be involved in hemolytic transfusion reactions and they increase the risk of Hemolytic disease of the fetus and newborn, so it is important for mother and the baby to have the same Rh factor.</span>
Answer and Explanation:
Enzymes are organic catalysts which are protein in nature. There are two types of naming enzymes:
<h3>Trivial naming</h3>
This method involves giving enzymes names based on the names of the persons who discovered them. The names of such enzymes end with the suffix-in, for example, pepsin, trypsin. Some of these names have been retained to date.
Enzyme Nomenclature by Enzyme Commission
This is the modern method of naming enzymes. The suffix-ase is added to the substrate or the reaction which the enzymes catalyses. Every enzyme code consists of the letters "EC" followed by the enzyme. For example
EC 1 oxidoreductases- oxidoreduction reactions
EC 2 transferases- transfer of a functional group
EC 3 hydrolases- catalyse hydrolytic cleaving
EC 4 lyases - adding groups to double bonds. e.g., C-C,C-O
EC 5 isomerases - catalyse structural changes in a molecule
EC 6 ligases - joining of two molecules
According to Newton's second law of motion,
acceleration= Net force divided by mass
Net force of A=10N
Mass of A=10kg
F/M
=10N/10kg = 1 m/s2
Acceleration= 1m/s2
