Explanation:

a. Lipids are biomolecules that are soluble in organic solvents.

b. A triterpene contains 30 carbons and six isoprene units, whereas a sesquiterpene contains 15 carbons and has three isoprene units.

d. Phospholipids are hydrolyzable lipids that contain a phosphorus atom.

e. A group of biologically active compounds containing 20 carbon atoms derived from arachidonic acid are called Eicosanoids .

f. Triacylglycerols, or trigylcerides, are esters that produce glycerol and three molecules of fatty acid upon hydrolysis.

succession returns a disturbed

ecosystem to a more stable state. this is also classified into two (2) types:

primary succession and secondary succession. the primary succession arises when

a new land is transformed and a bare rock has been exposed providing an environment

that can be occupied for the first time. while, secondary succession occurs

when a previously occupied environment was disturbed that kills much of all its

community
