be dead. If so, then jump-starting the car from a good battery will solve
the problem. Which of the following best describes your action?
Answer: stating a hypothesis and using that hypothesis to make a
testable prediction.

experiment, what following were held constant for the test group of 75
ants?
Answer: all variables except leg length (and therefore stride length)

Answer: nucleoid
,●● Pasteur's experiments demonstrated which of the following?
Answer: Pre-existing cells present in the air can grow in sterilized
nutrient broth

many which are lipid soluble. Which of the following structures is
primarily involved in this process and, therefore, abundant in liver cells?
Answer: smooth ER

adult flies.

flies appeared in only in the open jars. Which one of the following
statements is correct?
Answer: The experiment supports the hypothesis that maggots arise only
