Answer:
1. The objective lenses on a compound light microscope sample can be magnified either, 40x, 100x or 400x as it does have powers 4x, 10x, and 40x on the maximum power setting.
At 40x magnification Stella will see cell upto 5mm.
At 100x magnification Stella will be able to see cell and cell components upto 2mm.
At 400x magnification Stella will be able to see cell and cell structures more closely, 0.45mm, or 450 microns.
2. The white blood cells are stained here in purple and can be identified with their shape and size of nucleus in comparison to the red blood cells have bioconcave shape and smaller to the wbc, but the function of white blood cells does not allow them to have a set shape. And the white transparent part are platelets.
Answer:
The relative position of the genes on the chromosome is CABD
Explanation:
According to the observed recombination events, C and D are the furthest from each other, while C is closest to A, being therefore CABD the correct gene order in the chromosome
