The correct answer would most likely be D. In the absence of oxygen, cells release ATP by breaking down glucose into lactate. Which relates to lactase fermentation
The answer is B, space in a rock
Salinity density and the wind, temperature also affects it but not the moons temperature.
Answer: Rougher Surfaces
Explanation: Rougher surfaces have more friction between them than smoother surfaces. The rougher surface of the soles of the shoes causes more friction and slows you down.
A "hypothesis" is just an idea or proposal which someone comes up with
to try and explain a given set of observations. A hypothesis must be:
a)
falsifiable/disprovable
b) testable
c) have predictive value, in
order to be taken seriously by scientists, and to begin its journey
towards the status of "theory".
If it is an interesting proposal and is
deemed to possess these 3 criterion, scientists will start to
investigate it: what can it predict, what does it explain, is it
compatible with all the relevant data/observations? If it is supported
by enough experiments and/or observations, and gains acceptance by
enough of the "scientific establishment" (ie, by enough scientists who
are accepted and admired by their peers), at some undefinable point it
becomes a "theory". It can still be disproven at any time, but until
that happens it will remain a "theory" and may even graduate to the
status of "well supported theory", such as the theory of gravity or
relativity. At NO point, however, is ANY theory ever considered by
scientists to have been "proven": in the scientific world, all truth is
"relative". and provisional.
