While both carbohydrates and lipids are made up of carbon, hydrogen and oxygen there are several differences:
1. Carbohydrates are chains of 2 or more carbon atoms. These can be very lengthy (like long cellulose chains of glucose units). They have many polar OH groups (e.g. glucose - C6H6O6). Most carbohydrates are hydrophilic and are soluble in water because of their polar OH groups. They are not necessarily sugars nor are they necessarily sweet. They are also important components of DNA, RNA and ATP.
2. Lipids are more diverse in their chemistry. They generally have a polar region at one end (this end attracts water) and a large non polar hydrocarbon region that repels water. Lipids don't dissolve in water and instead clump together with their hydrocarbon regions on the interior. Lipids include oils, fatty acids, waxes, steroids and hormones.
The correct answer is D. Salt water.
Explanation
The hydrosphere is the system that groups all the waters of the earth that include oceans, seas, rivers, lakes, lagoons, frozen waters like ice and snow, among others. The water of the earth can be classified between salt water and freshwater, within the first group we find the oceans and the seas that represent two thirds of the total water of the earth, that is, 93 percent of the total water of the earth, a figure close to 1 370 323 000km³; the rest of the water is fresh and consists of rivers, lakes, lagoons, streams, groundwater, and glaciers. So, the correct answer is D. Salt water
