Jules wanted to know whether the eating behavior of goldfish is affected
by music. He set up a fist tank. Every day, Jules played music for the fish
and measured how much the fish ate. What is Jules missing from the
experiment?
O
A control group
O
A measurable result
O
Different types of fish
O
An outcome variable

i think Jules is missing a control group because it does not say that he fed the fish with no music playing or just with all the genres playing on different days then one day no music at all so i think its a control group.

the darker peppered moth species were favored due to the fact that the industrial revolution had made all the nearby trees a darker color instead of white.

he movement of air through earth's or any planet's atmosphere is called wind, and the main cause of earth's winds is uneven heating by the sun. this uneven heating causes changes of atmospheric pressure, and winds blow from regions with high pressure to those with low pressure.

i hope this : )
