A mechanic invented by eli whitney that removes seeds from cotton much more more quickly and effectively than by hand.
I see pictures above , what do you exactly need help with?
Answer:
Fatty acids have a carboxyl group at one end of a hydrocarbon molecule.
<u>The carbon atoms in saturated fatty acids are linked entirely by single C-C bonds.</u>
Unsaturated fatty acids contain one or more double bonds.
<u>Double bonds cause molecules to bend, and they can pack less tightly.</u>
