What would be a valid conclusion to draw from this data? a) all methods are effective in killing bacteria. b) both soap brands out perform hand sanitizer in killing bacteria. c) warm water is as effective as soap or sanitizer in killing bacteria. d) hand sanitizer is more effective than either soap in killing bacteria.

B) Both soap brands out perform hand sanitizer in killing bacteria.

Looking at the data, the conclusion is pretty obvious, the two different types of soap resulted in about half the bacteria cultures as either the hand sanitizer, or just using warm water. In fact, the hand sanitizer looks like it's even worse than simply using warm water. So looking at the four available options, the best choice is "B) Both soap brands out perform hand sanitizer in killing bacteria."

Explanation:

any abiotic or biotic factor in an ecosystem that causes a population's size to slow or decrease is a limiting factor.

idk what the options are but

these is a strong electrostatic attraction between the ions hence a lot of energy is needed to overcome this attraction

this is why the boiling points are so high
