Below is the molecule for caffeine. Give the molecular formula for it.
Below is not the molecule for caffeine. Below is just a rectangle.

3.26 kg
The correct answer should be 3.3 kg.
-
29.3 g/cm3
This answer seems not to be correct. The correct answer should be 0.00293 in the scalar part.
-
790 g/L
This is only true if we use American gallons not the main gallons.
-
0.3.27 kg
What is this value anyway? It should be 0.235 g.

This idea is explained in the figure below.
Both flasks look the same.

Since on the earth, the ggg in the equation is equal to one, weight and mass are considered equal on earth. It is important to note that although ggg is equal to one in basic equations, it actually differs throughout earth by a small fraction depending on location; gravity at the equator is less than at the poles.
g is not equal to one.

a carbon atom has a total of six electrons it's Lewis symbol has four unpaired electrons
How does a carbon atom have four unpaired electrons if it only has two of them?

Prokaryotes were the first inhabitants on Earth, appearing 3.5 to 3.8 billion years ago.
How does this allegation concur to the postulate that eukaryotes were first and prokaryotes were evolved later?

A lysogenic cycle kills the host cell.
What about this one? In lytic cycle, the host cell will be killed, not in lysogenic cycle.

vertical transmission transmission of disease between unrelated individuals
This is horizontal, not vertical.

horizontal transmission transmission of a disease from parent to offspring
This is just not true. This is vertical.

acetylation
Did you mean deacetylation as acetylation makes it possible to transcribe and not gene silencing.

RNA stability is controlled by RNA-binding proteins (RPBs) and microRNAs (miRNAs). These RPBs and miRNAs bind to the 5' UTR or the 3' UTR of the RNA to increase or decrease RNA stability.
RBP, not RPB

If the round pea parent is heterozygous, there is a one-eighth probability that a random sample of three progeny peas will all be round.
Please clarify how you calculated 1:8 ratio. One plant has rr and the other plant has Rr. You create a table and get two Rr and two rr which makes the probability of getting three Rr or RR zero.

the cytoplasm in plants is always slightly hypertonic to the cellular environment, and water will always enter a cell if water is available.
Did you mean hypotonic? Because water enters the cell in a hypotonic situation, not in the hypertonic situation as described before.

Therefore, as a cell increases in size, its surface area-to-volume ratio decreases.
This is an incorrect statement considering the two given formulas for the sphere and that the cell is in the form of a sphere. The surface are to volume ratio stays constantly three.
-
its volume increases as the cube of its radius (much more rapidly)
This is an incorrect statement. Using the given formula for the sphere volume, the volume doesn't increase as the cube of its radius but also by the magnitude of power of two.
