Answer:
covalent, which repel water molecules
they contain ions, which make the entire molecule hydrophilic
they are less dense than liquid water, so they float on the surface
most of their bonds are nonpolar covalent, so they are not attracted to water

Answer:
A. Abrasion
Explanation:
<em>"In abrasion, one rock bumps against another rock. Gravity causes abrasion as a rock tumbles down a mountainside or cliff. Moving water causes abrasion as particles in the water collide and bump against one another."</em>

Answer: Carbon 12 and Carbon 13
In plant, the ratio of carbon 12 and carbon 13 isotopes is different depending upon the plant photosynthesis. The distribution of these isotopes in plant tissue can indicate the path way of carbon metabolism that is either C3 fixation or C4 fixation. This help scientist to know if the plant consumed by organism is C3 plant or C4 plant by measuring the isotopic signature of their collagen and other tissues.
This can help scientist know which plant is consumed by animals.
Air pressure is the amount of pressure exerted by the air in a particular air mass. Humidity is a measure of the water content of the air mass. Clouds are tiny drops of water or ice that form in the atmosphere. Wind is a process of movement of air that occurs due to the uneven heating of the Earth's surface.
