The ABO blood groups in humans are expressed as the IA, IB, and i alleles. The IA allele encodes the A blood group antigen, IB e

ncodes B, and i encodes O. Both A and B are dominant to O. If a heterozygous blood type A parent (IAi) and a heterozygous blood type B parent (IBi) mate, one quarter of their offspring will have AB blood type (IAIB) in which both antigens are expressed equally. Therefore, ABO blood groups are an example of:
multiple alleles and incomplete dominance
codominance and incomplete dominance
incomplete dominance only
multiple alleles and codominance

Answer:

Multiple alleles and codominance

Explanation:

Co dominance may be defined as the phenomena in which both the alleles can express themselves independently in heterozygous condition. The involvement of more than two alternative form of a single gene is known as multiple allele.

The ABO blood group represent the example of codominance and multiple allelism. In case of AB blood group both the alleles I(A) and I (B) express themselves in heterozygous condition and result in the formation of AB blood group. Different alleles like I(A), I(B), I(A)I(B),i are involved in case of ABO blood group, this shows multiple allele.

Thus, the correct answer is option (4).

Answer:

C. surface tension

Explanation:

Surface tension refers to the property of water or any liquid to enhance its surface area by a certain amount. It is a very important property of water due to which it resists  any external force due to cohesive nature of water molecules.

How surface tension help needle to float on water:

It is a property of water which enhance the attractive force between needle and liquid.

The molecules on the surface of water do not have any force acting from upwards because that side is exposed to atmosphere. This causes a downward force but no upward force on upper surface,so the molecule of surface tend to stay together by forming a thin sheet or imaginary layer.

If weight of any material cannot break surface tension it will float on water surface. This is what happens with needle.Therefore, when needle is placed on water surface with alot of care in horizontal direction, it will not break surface tension and hence will float on water. Please see attached image for better understanding.

Hope it clears up the picture!
