Answer:
Y= 98, 0% , Z = 94,7 %
Explanation:
We use simple 3 rules to find the percentage of purity, using mass data:
Sample Y =
85g----100%
83,30g----X = (83,30gx 100%)/ 85g= 98, 0%
Sample Z =
95g----100%
90g----X = (90gx 100%)/ 95g= 94, 7%

The Punnett square is a diagram used by biologists to calculate the probability that an individual has a particular genotype. In the Punnett square, each of the possible combinations for the expression of the dominant and recessive alleles can be observed. In the case of exercise, since a crossing is not possible in men, these will only help later during the combination of the alleles.
The measurements taken by Jay are least likely to contain random errors.
When you increase the number of measurements, the random errors tend to minimize, because errors in one direction cancel with errors in the opposed direction.
The phase contrast microscope uses out-of-phase and in-phase light rays that produce contrast areas allowing scientists to detect even a minute number of protein molecules and focus on the minute internal structures of a particle.
