Each ABO blood group is associated with the presence/absence of RBC antigens and the presence/absence of antibodies in the plasm
harina [27]

Answer:

a. Type O blood - No A or B antigens on RBCs-Anti-A antibodies in plasma-Anti-B antibodies in plasma

b. Type A blood - A antigen on RBCs- Anti-B antibodies in plasma

c. Type B blood - B antigen on RBCs- Anti-A antibodies in plasma

d. Type AB blood - A antigen on RBCs- B antigen on RBCs- Neither anti-A or anti-B in plasma

Explanation:

ABO blood grouping system represents multiple allelism which was discovered in humans by Karl Landsteiner. The blood group is determined by the presence or absence of A & B antigens and antibodies.

The 4 blood groups which exist in ABO system are O, A, B and AB. Also, allele A and B are co-dominant i.e. if they both will exist on the surface of an RBC then both will be equally expressed which implies that there will be no dominant or recessive allele.

Type O blood group has H antigen on the surface of RBC and has both the antibodies i.e. antibody A and B. The absence of antigens A and B makes it a universal donor.

Type A blood group has A antigen on RBC and has antibody B in the plasma.

Type B blood group has B antigen on RBC and has antibody A in the plasma.

Type AB blood group has both the antigens i.e. antigen A and B on RBC and does not have any antibody in the plasma which makes it a universal acceptor.

Montano1993 [528]

The soil, fertilizers, and pesticides eroded by the surrounding waterways are transported via the water to a location different from their former one. These are taken away by the water flow and deposited in the delta area of the river. This delta is a land-form which is formed by the deposition of the similar substances, where the flow of the river is slower.

Hence, the correct answer is 'Option B'.
