The appropriate answer is A. the density of ice would be greater than the density of liquid water and so ice would not float. Density can be defined as mass per unit volume. Any substance whose mass is great and occupies a relatively small volume is going to be dense.
Water expands by nine to ten percent when it freezes and this expansion increases the space occupied or the volume and so the density of ice is less than water.

A - 3:1
Explanation:
In order to determine what number of offspring will have attached earlobes, we must make a Punnett table. We know that attached earlobes are the dominant gene, and we know unattached earlobes are recessive.
| P | p
