I cannot found the images of the microscopy anywhere. But I can explain how you can differentiate a procaryote from a eucaryote under a microscope.
The first difference between them is the size of the cell. eucaryotes are generally much bigger than procaryotes. Procaryotes are visible only at x100 objective, but eucaryotes are visible starting from the x10 zoom.
The second difference is the presence of a nucleus in eukaryotes and the absence of it in procaryotes.
The third difference is the presence of organelles in eukaryotes and the presence of a cell wall in procaryotes (only visible at electronic microscopy).
I might be incorrect, but from what I remember it should be particle size
Answer:
ppss and PPSS
Explanation:
Just as indicated in the question above, Flies homozygous for singed and purple were crossed with flies that were homozygous for normal bristles and red eyes.
And a Drosophila mutation called singed (s) causes the bristles to be bent and misshapen.
A mutation called purple (p) causes the fly’s eyes to be purple in color instead of the normal red.
Thus, the genotypes of the parental flies in Cross 1 are
PPSS and ppss
