The answer is purple and smooth.
It is known that the in dihybrid cross (a cross between two
different traits), the phenotypic ratio between the offspring of two heterozygous parents in the F2
generation is 9:3:3:1.
<span>purple and smooth = 75 (</span><span>≈ 9 </span><span>· 8)</span>
<span>white and smooth = 28 (</span><span>≈ 3 </span><span>· 8)</span>
<span>purple and wrinkled = 24 (= 3 </span><span>· 8)</span>
<span>white and wrinkled = 8 (= 1 </span><span>· 8)</span>
<span>
</span>
So, the ratio between the offspring is close to 9:3:3:1 in F2 generation.
This means, that the only heterozygotes are present in the F1 generation, and they must be purple and smooth.
It Can Squish Together To Form Into Something
I believe the correct word in the blank would be biological. I don't think anything else will fit in, especially when monomers of biological polymers are truly larger and more complex.
Answer:
Nitrogen and phosphorus are among the elements considered most limiting to plant growth and productivity because they are often present in small quantities locally or are present in a form that cannot be used by the plant.
