Yes,
ex: Hydrogen
Can traits acquired of the course of an organism's life be passed
on to their offspring? Correct Answers Yes
Carbonyl group Correct Answers (CO)
--->C=O
Carboxyl group Correct Answers -COOH

Define quaternary structure of a protein. Correct Answers 2 or
more polypeptide chains to form one macromolecule
ex.
-Collagen
-Hemoglobin
Describe fats Correct Answers -Constructed from glycerol and
fatty acids
,-Triglyceride: 3 fatty acids joined to glycerol by an ester linkage
(dehydration synthesis)
-Saturated fat have no double bonds
-Unsaturated fat have one or more double bond
Hydrogenation: Convert unsaturated fats to saturated by adding
hydrogen
=TRANS DOUBLE BONDS=trans fat
Describe how energy flows through an ecosystem Correct
Answers Starts from sunlight, then each level of the ecosystem
gets energy from its food source
