I think you mean Round could be RR or Rr (round is dominant to wrinkled)
R=round
r=wrinkled
RR would be round phenotypically
Rr would be round phenotypically
To determine if they are RR or Rr you should perform a backcross with a wrinkled mutant!
I put a picture to demonstrate this.
If they are RR then if you cross with rr you would only get phenotypically Round pea plants.
If they are Rr then if you cross with rr you would get 50% round and 50% wrinkled. Any wrinkled? Definitely the heterozygote Rr!!

Which of the following causes macromolecules to be classified as organic molecules? carbon hydrogen nitrogen oxygen

Tamiku [17]

<span>Carbon is the answer you are looking for. However, not all carbon containing molecules are organic. Examples being carbon oxides such as CO (carbon monoxide) and CO2 (carbon dioxide). Some Chemists classify organic compounds as having a C-H bond present but this is not completely correct as this excludes molecules like benzenehexol (benzene with an alcohol group on each carbon rather than a hydrogen) which are considered organic. A solid definition of an organic molecule is not certainly agreed. Just remember that: all organic molecules contain carbon but not all carbon containing molecules are organic.</span>
