Q

Why is it important that you have a control group in an experiment?

A

To give a reliable baseline for comparison on how an organisms reacts under “normal” circumstances

So that it becomes possible to compare treatment groups to an untreated group

214
Q

the end closest to the umbo

216

Q

The principal components of the insect exoskeleton are proteins and a type of carbohydrate called _________.

A

Chitin

225
Q

Why are replication and reasonably large sample sizes important in an experiment?

A

To increase the (potential) significance and reliability of the results (if there actually was a difference between treatments).

To reduce the standard errors within experimental groups.

To provide stronger evidence regarding the hypothesis you are testing.

230
Q

Because the exoskeleton is rigid, arthropods must shed it periodically, to grow in a process known as molting, or __________.

A

ecdysis

231
Q

Why, in the guppy choice experiment, is it important that the tank be centered over the red line?
