Answer:
Explanation:
The symbiotic relationship between a flower and the insect that feeds on its nectar is an example of a. mutualism because the flower provides the insect with food and the insect pollinates the flower.
To be completely honest, I think all of them, in a way, support the theory.
The common animals show that the animals were spread out over all the land, making it joined
The coastlines matching show they were once joined
the earthquakes only happen in boundaries, where the countries were joined before
I'm not so sure about the last one, sorry
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.
