Answer 1

$\huge\underline\bold\red{AnsWer}$

Explanation:

Arachidonic acid consists of 20 carbon atoms with five double bonds while each one among oleic, linoleic, and linolenic acid contains 18 carbon atoms. The number of double bonds in oleic, linoleic, and linolenic acid are two, three, and four respectively.

Answer 2

An unsaturated fat is a fat or fatty acid in which there is at least one double bond within the fatty acid chain. ... Thus, a saturated fat has no double bonds, has the maximum number of hydrogens bonded to the carbons, and therefore is "saturated" with hydrogen atoms.
