Which of the following best describes why ice has a lower density than liquid water?

Choose 1

(Choice A)

There is more space between individual atoms at lower temperatures, which means colder water has a lower density.

(Choice B)

Because water changes from its polar form as a liquid to its nonpolar form as a solid.

(Choice C)

The water molecules have less atomic motion than ice.

(Choice D)

Hydrogen bonding causes water to crystallize with more empty space between molecules than in the liquid state.

Two male mice, which we will call male a and male b, are both phenotypically normal. male a was from a litter that contained half phenotypically normal mice and half dwarf mice. the mother of male a was known to be homozygous for the normal igf2 allele. male b was from a litter of eight mice that were all phenotypically normal. the parents of male b were a phenotypically normal male and a dwarf female. male a and male b were put into a cage with two female mice that we will call female a and female b. female a is a dwarf and female b is phenotypically normal. the parents of these two females were unknown, although it was known that they were from the same litter. the mice were allowed to mate with each other, and the following data were obtained: female a gave birth to three dwarf babies and four normal babies. female b gave birth to four normal babies and two dwarf babies. which male(s)mated with female a and female b? male a with both females male a with female b, and male b with female a male a with female a, and male b with female b could not be determined male b with both females
