consists of fats, phospholipids, and steroids. Includes cholesterol and saturated fats are peimarily sugar and starches

Explanation:

Lipids are the esters of fatty acids. They are hydrophobic and play an important role in cell membrane structure. Some lipids like triglycerides act as a storage compound for reserve energy. They provide energy to the body. These are soluble in ether, alcohol, benzene, etc. It consists of C, H, N, O, P.  

There are different types of lipids such as - simple lipids, compound lipids, and steroids.  

The simple lipids only consist of fats and alcohol. Examples of simple lipids are fats and waxes. Fats are also two types- saturated and unsaturated.

The compound lipids consist of other substances besides fatty acids and glycerols. These are phospholipids,  glycerophospholipids, glycolipids.  Phospholipids are the lipids having glycerol, phosphoric acids, and fatty acids.  

Steroids do not contain fatty acids. The important steroids are cholesterol and ergosterol. The ergosterol is the precursor of vitamin D.

the answer to this predicament is false, by friend, i had this on a quiz, and i got it wrong, so i learned it, cos i was gonna have it on a test, and i got it right

c. earths continental crust is thicker than its lithosphere.

because, the lithosphere is the outermost layer of the earth/ 100 km thick and is defined by its machanical properties.the lithosphere contains oceanic and continental crust that varies in age and thickness across locations and geologic time. the lithosphere is the coolest layer of the earth in terms of temperature. the term lithosphere should not be confused with the use of "geosphere" which is used to indicate all of earth systems, including the atmosphere, hydrosphere   and biosphere. the surface of the earth can be divided into the continental crust and the oceanic crust.   the continental crust is made mostly of granite while the oceanic crust is made of basalt. the average thickness of the continental crust is 25 miles and the average thickness of the oceanic crust is 5 miles.   three types of rock, igneous, sedimentary, and metamorphic, make up the surface of the earth. that's why 3 option is preferable.
