Select all of the answers that apply. warm water is less dense than cold water is more dense than cold water has higher salinity than cold water has lower salinity than cold water is found near the poles

is less dense than cold water

has lower salinity than cold water

The warm water will be less denser than the cold water. The cold water being more denser sinks at the bottom of the pole and it moves towards the equator. The warm water remains at the surface of ocean. It exhibit very low salinity as compared to cold water.

what have scientists found to be the most efficient and effective way to insert new sequences into an individual? a-scientists have created genetically altered foods that release dna during digestion. b-scientists use viruses to insert specific gene sequences. c-scientists irradiate genes so that they can be absorbed through the skin.

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.
