Answer:
I. Overall magnification (TM) = x40
II. Overall magnification (TM) = x100
III. Overall magnification (TM) = x400
IV. Overall magnification (TM) = x1000
Explanation:
A microscope can be defined as an optical device that is typically used to make an enlarged (magnified) image of a minute (small) object and as such reveals all the little information about the object that cannot be seen by the natural human eye.
Mathematically, the overall (total) magnification of a microscope is given by the formula;
Overall magnification (TM) = Eyepiece magnification(EM) X Objective magnification (OM).
I. When EM = x10 and OM = x4
TM = EM * OM
TM = x10 * x4
<em>TM = x40</em>
II. When EM = x10 and OM = x10
TM = EM * OM
TM = x10 * x10
<em>TM = x100</em>
III. When EM = x10 and OM = x40
TM = EM * OM
TM = x10 * x40
<em>TM = x400</em>
IV. When EM = x10 and OM = x100
TM = EM * OM
TM = x10 * x100
<em>TM = x1000</em>
<span>The answer to the question is 0 percent. In order to have wrinkled seeds, the offspring must inherit two recessive alleles from the parents. From the cross of RRYY and RrYy, there is no way for the offspring to have wrinkled seeds as one of the parents doesn't have the recessive gene for it, the RRYY parent. Because of this there is 0 percent probability of having an offspring that has wrinkled seeds and yellow seed color.</span>
