Mother-foetus Rh blood type incompatibility disorder can occur if the mother_____________________is and her foetus is___________
1 $\text{Rh}$ positive; $\text{Rh}$ positive
2 $\text{Rh}$ positive; $\text{Rh}$ negative
3 Rh negative;$\text{Rh}$ positive
4 Rh negative;$\text{Rh}$ negative
Explanation:
(c) In order for the foetus to be $\text{Rh}$ positive, the father must also be Rh positive. As a result, when the mother is $\text{Rh}$ negative and the father is $\text{Rh}$ positive (or his $\text{Rh}$ type is unknown), doctors usually assume that there will be a serious medical problem.

Clotting of blood is to
1 seal up wounds and prevent blood loss
2 slow down the movement of blood inside the blood vessels.
3 trap oxygen inside the blood so that it can be carried around more easily.
4 trap harmful germs inside the blood and prevent them from harming the body.
Explanation:
(a) The clotting of blood is to seal up wounds and prevent loss of blood. Platelets in blood releases clotting chemicals at the site of injury which forms a clot and prevent bleeding.

When the blood of a foetus is agglutinated by its mother's $\text{Rh}$ antibodies, then which of the following condition arises as a severe anaemia?
1 Immunization
2 Ectopic pregnancy
3 Erythroblastosis foetalis
4 Both (b) and (c)
Explanation:
(c) Erythroblastosis foetalis is a type of haemolytic disease of new-borns due to ABO blood type incompatibility. This occurs when a mother's blood type of $A,B$, or $O$ is not compatible with a blood group of foetus. It develops in a foetus, when the IgG molecules produced by the mother pass through the placenta. Among these antibodies are some which attack the red blood cells in the foetal circulation; the red blood cells are broken down and the foetus can develop reticulocytosis and anaemia. This foetal disease ranges from mild to very severe, and foetal death from heart failure (hydrops fetalis) can occur.
