Answer:
answer is the 1st option (A)
But we need to see the graph in order to answer the question
<em>Four main classes that define a macromolecules are</em><em> </em>
- <em>Protein</em>
- <em>carbohydrates </em>
- <em>lipids</em>
- <em>nucleic acid</em>
<u>EXPLANATION: </u>
Macro-molecule is a large molecule which can contain more than 100's and 1000's of atoms. They are different from the smaller molecules and each macro-molecule does more than one function.
Macro-molecules are made up of single elements of monomers joined using covalent bonds and a large polymer is formed. For example, one molecule of polyethylene which is plastic has more than 2500 methylene groups, each one of them has two hydrogen and one carbon atoms.
Incomplete dominance is when a cross between two true breeds (homozygous) having different genotypes and phenotypes result in an heterozygous offspring expressing a third trait, usually a blend of those of the parents.
An example is crossing between red and white roses resulting in pink roses.
The condition to conclude incomplete dominance is that the heterozygous individual expresses a trait which is different from, and is a blend of, the traits of the parents.
