Which scientist disproved spontaneous generation for all time?

• Redi

• Pasteur

• Spallanzani

• Oparin

In his experiment, Redi covered one of the jars with a cloth. The purpose of the cloth covering was:

• to keep the vital force inside the jar

• to keep flies from entering the jar

• to keep maggots from leaving the jar

• to keep the meat inside the jar from rotting.

What conclusion was reached by Redi?

• Maggots are produced by flies.

• Maggots arise spontaneously in rotted meat.

• There is no correlation between covered jars, flies, and maggots

• A cloth covering will prevent vital force from entering the jar.

Pasteur used a curved neck flask in his experiments. Why was this a good choice for his experiment?

• It prevented air from entering the flask.

• It made boiling the broth much easier.

• It prevented vital force from leaving the flask.

• It prevented new microorganisms from entering the broth.
