The correct answer here would be mole, as this is the unit of
measurement used to determine the amount of a substance being used. This
particular measurement is usually used during chemistry experiments as
it determines how many representative particles there are in any one
amount of substance.

Option D is a correct answer
Explanation:
An adaptation is adapted to suit the environment as every environment is different.
Different environment aids to different kind of adaptations that perfectly suits the animals living there.

Answer;
-The less dense, the more the ice will float, allowing animals to stay afloat and not in the water
Explanation;
-When water freezes, water molecules form a crystalline structure maintained by hydrogen bonding. Solid water, or ice, is less dense than liquid water. Ice is less dense than water because the orientation of hydrogen bonds causes molecules to push farther apart, which lowers the density.
-This means that ice floats on water and that lakes freeze from the top down to the bottom.This is vital for animals that live on ice, as their habitats would be greatly reduced or not exist at all if ice sank.
Answer:
Griffith and Avery studied bacteria and mice. Their S and R experiment revealed that DNA stores and transmits genetic information from one generation of bacteria to another. Chromosomes consist of protein and DNA, but mainly DNA.
