98. All of the following are true of water EXCEPT A) neighboring molecules are held together by hydrogen bonds. B) it is less de
Anon25 [30]

Answer:

C) it is a polarized molecule, where the oxygen is slightly positive and the hydrogens are slightly negative.

Explanation:

The water molecule is polarized, but the oxygen atom is slightly negative and the hydrogens are slightly positive.

Electronegativity is a property that measures how much an atom will tend to attract electrons towards itself. Because electrons are negatively charged, the more electronegative an atom is, the more negative its partial charge will be.

Oxygen is much more electronegative than hydrogen, and thus it will attract the electrons in the molecule, keeping them away from the hydrogens.

Show how evolution could have occurred by the process of natural selection
Karo-lina-s [1.5K]

Natural selection is basically a way for nature to choose what works and what doesn't work.  For example, if an animal was born with webs to swim, but most of its food source can be gotten on land, then the animal will die off until it evolves to go on land.  That is how evolution works with natural selection.  In the past long ago, millions of years back, animals in the water needed oxygen to breath, but the water started to lose it.  The land had air, and then the fish slowly grew legs, and their gills would evolve to lungs.  Eventually they would be able to roam the land.  Because there was so much oxygen with all of the shrubs, trees, and plants, that allowed the bodies of animals to grow big.
