Christopher is studying the motion of objects, so he makes the following hypothesis. As the mass of an object increases,
its inertia also increases.
What is the independent variable in Christopher's study?

it's anything that aren't producers and consumers.

explanation:

you've got to be clear on what "this" is

the answer is trees if i'm not mistaken

the answer would be 2, if crossing over doesn’t occur 2 out of 4 of the daughter cells will have that allele.

hope this : )

hydrogen is a compound or a single element and a element is a pure substence that cannot be separated into simpler subtances

clorine is a compound its a chemical substance that forms when two or more different elements combine

so both hydrogen and clorine are compounds
