Answer: for an object or gas or liquid to float in another there must be a difference in density
Explanation:
Helium has a density of 0.18 kg/m³ and air has a density of 1.29 kg/m^³. If a balloon is filled with helium it will float in air due to density differences
Archimedes' principle states that the upward buoyant force that is exerted on a body immersed in a fluid, whether fully or partially submerged, is equal to the weight of the fluid that the body displaces
Mutation affect a species ability to survive and reproduce. Mutations can expand the life span of a species by keeping them hidden from predators which would also increase reproduction. If exposed to other wildlife, those numbers could decrease.
<span>it is limited to situations that involve aqueous solutions of specific compounds

Explanation:
The molecules in water is more tightly packed than in ice, so water has greater density than ice.
