Which of the
following is NOT
important in an
experiment?

Options

A. working in a controlled environment

B. recording all data and keeping it consistent

C. making sure that only one variable is being changed

D. performing the experiment in the same location

that the observations were done in

D is the correct answer, We do not need to an experiment where we first observed it, here is a great example. The sun fuses hydrogen atoms to make helium and energy in the form of light. scientists first observed this in the sun, but that doesn't mean we can only conduct nuclear fusion in the sun. we do it here on earth all the time.

when a reversible reaction is occurring in both directions at the same rate; the products and reactants do not change in concentration. a chemical reaction where the compound is broken into its constituent parts.

a. population growth is decreasing

-2

+4

-10

-3

-8

-3

so the population decreased by 24 because 3+3+8+10+2=26-2=24.
