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!
Explanation:
both IA and IB are dominant- A and B groups show co-dominance
Inheritance describes the way in which certain traits are passed onto offspring of sexual reproduction. For co-dominance, both of a gene's alleles are present, and notable in the phenotype.
Blood glycoprotein alleles are crucial to blood type determination for the ABO system in humans- i does not lead to modifications, while IA leads to the modification of adding N-acetylgalactosamine to the H-antigen on red blood cells; and IB adds galactose
= blood type AB while
= blood type A while
= blood type B. Since
are both dominant over ii, those with that allele have blood type O.
The nucleus is a large membrane-bound organelle that houses the genetic information, DNA, in the cell. Sequences of DNA make up genes which can have different forms called alleles and comprise the genotype. DNA is transcribed into mRNA and later translated into amino acids which are linked together by rRNA to form proteins. These proteins, when expressed, are referred to as an organism's phenotype.
