Jorge has made the hypothesis that the more he feeds a mouse, the shinier its fur will be, because the mouse will be healthier.
LuckyWell [14K]

The correct answer is D. The amount of food he feeds each mouse

Explanation:

In research, the independent variable refers to the variable or factor that is manipulated by the researcher. Besides this, the independent variable affects the dependent variable or factor being studied. This implies in the case presented, the dependent variable is how shiny mice's fur is because this is the variable being studied; on the other hand, the independent variable is the amount of food Jorge feeds to each mouse because this is the factor Jorge would manipulate or change to prove if the amount of food has an effect on the fur of mice.

A wave in which the particles of the medium move up and down as the wave passes through is a transverse wave or a
ANTONII [103]

Answer:

transverse waves

Explanation:

this is because the definition of transverse waves is transverse waves are waves that travel perpendicular to the direction of the wave motion

however the definition of longitudinal waves is that longitudinal waves are waves that travel parallel to the direction of the wave motion.

so you can see the parallel means it forms compressions and rarefactions

but perpendicular means the particles will move up and down to the straight horizontal line, that's how lines are perpendicular right? ,

so the answer is transverse wave

hope this helps

please mark it brainliest
