I would say (A) because it allows the bacteria (bacteria X) to be exposed to the control condition and the experimental condition so that a cause-effect relationship can be established. Here, the control condition would be the darkened area and the experimental condition would be the lightened area.

Answer:
I would expect that the sample has only 50% of the original 235 U.
Explanation:
That is because 235 U has a half-life of 700 million years and I expect that my sample be 350 million years old. 350 is half of 700.
The correct answer is "transmission electron microscope".
The transmission electron microscope can magnify the organelles of the cell clearly; as in light microscopes wherein most organelles cannot be visualized. TEM works by using a beam of electrons to pass through a specimen to make a clear image. Because of its superior magnification, mitochondrial defects can be visualized easily.
Attached is a sample picture of a transmission electron microscope image of a mitochondria.
D = m/v
Given:
D: .835 g/cm3
V: 34 cm3
M: ?
M= Dxv
M= .835 g/cm3 x 34 cm3
M= 28.39 g
