Answer:

Letter A, Electron microscope

Explanation:

The electron microscope is used to visualize high-resolution images of biological specimens. It used to see in detail very small  cells, organelles, cells tissues,  molecular complexes, etc. The ribosome is a complex molecule made of proteins where the translation of proteins is made, it is very small that can be seen in detail using the electron microscope.

In tomato plants, the allele for purple stems is dominant to allele for green stems and the allele for red fruit is dominant to
Kamila [148]

So let's call the allele that is dominant for purple stems is P, and the recessive allele yielding green stems is p. And let's say that the allele that is dominant for red fruit is R and the recessive allele for yellow fruit is r.


The two plants are each heterozygour for both traits, meaning that the cross is going to be:


PpRr x PpRr


So let's setup a Punnet Square:


\left[\begin{array}{ccccc}&PR&Pr&pR&pr&PR&PPRR&PPRr&PpRR\4&PpRr&Pr&PPRr&PPrr&PpRr&Pprr\\pR&PpRR&PpRr&ppRR&ppRr&pr&PpRr&Pprr&ppRr&pprr\end{array}\right]


The genotypic ratios (alleles) and phenotypic ratios are as follows:


PPRR (Purple stem, Red fruit): \frac{1}{16}


PpRR (Purple stem, Red fruit): \frac{2}{16} or \frac{1}{8}


ppRR (Green Stem, Red fruit): \frac{1}{16}


PPRr (Purple stem, Red fruit): \frac{2}{16} or \frac{1}{8}


PPrr (Purple stem, Yellow fruit): \frac{1}{16}


PpRr (Purple stem, Red fruit): \frac{4}{16} or \frac{1}{4}


pprr (Green stem, Yellow fruit): \frac{1}{16}


ppRr (Green stem, Red fruit): \frac{2}{16} or \frac{1}{8}


Pprr (Purple stem, Yellow fruit): \frac{2}{16} or \frac{1}{8}


So then we take the like phenotypic ratios and add them together:


Purple stem, Red fruit: \frac{1}{16} +\frac{2}{16} +\frac{2}{16} +\frac{4}{16}=\frac{9}{16}


Green stem, Red fruit: \frac{1}{16}+ \frac{2}{16} =\frac{3}{16}


Purple stem, Yellow fruit: \frac{1}{16}+ \frac{2}{16} =\frac{3}{16}


Green stem, Yellow fruit: \frac{1}{16}
