The nucleus. If a cell has a nucleus it is eukaryotic if it doesn't, it is prokaryotic.
The property of ice that allows it to float in water is ice's low density.
<h3>What is density?</h3>
It is a property that measures the mass of substances relative to their volumes.
The density is mathematically givens as, density = mass/volume.
Thus, the mass of a substance is directly proportional to its density.
Ice is less dense than water and according to the principle of floatation, substances whose densities are lower than that of water will always float on it and vice versa.

Answer:
The correct answer is - A. 25%.
Explanation:
In humans, the blood group system is known as the ABO system where blood groups A and B are codominant and O blood group is recessive. The genotype of the A blood group could be AA or AO similarly for the B blood group genotype would be BB or BO, for the O blood group OO whereas for the AB blood group both A and B alleles should be present together.
Cross: AB blood type father with an A blood type mother (genotype AO)
Gametes: A, B and A, O
Punnett square:
A B
A AA AB
O AO BO
Here, there are 25% chances of AB blood group offspring 50% for the A blood group (AA and AO) and 25% B blood group (BO).
