Compare the three types of specialized cells that you viewed through the microscope to the generalized cell that you built in Part 1. List which organelles each specialized cell might need in greater numbers than the generalized cell. Offer a reason for each answer.

try using substitution:

x + y - 6 = x - y. (i'm not giving you the exact answer). since 0 = x - y, then sub 0 in the equation with x - y. combine your like terms, and then use inverse operations, and you'll have your answer.

not sure if this is what you'r looking for eubacteria and archaebacteria

this age may represent the age of the earth's accretion, of core formation, or of the material from which the earth formed. this dating is based on evidence from radiometric age-dating of meteorite material and is consistent with the radiometric ages of the oldest-known terrestrial and lunar samples.
