The measurements to be comparable in both, Ask an Expert

Academics

Q1. The polar lobe produced in the 1-cell zygote of llyanassa snookii is inherited by only one of the two cells in the 2-cell zygote. You wish to explain that, as in other snails such as llynassa obsoleta, cleavage of the zygote produces two daughter cells that are no longer totipotent. Illustrate one experiment you could perform to demonstrate such lack of equivalence of the two cells in the zygote. Noticeably state the expected outcome of your experiment in the reply you provide.

Q2. Comparative study of microbial size, using a stage micrometer, requires that you measure Bacillus subtilis in both the stained and unstained states. Would you expect the measurements to be comparable in both preparations? If a variation in size is expected, how will you account for this difference?
