bart believes that mice given special food will become extra strong. he decides to perform this experiment by giving 10 mice in a special food for 14 days. he compared these 10 mice to another 10 mice that had normal food for 14 days. his test consisted of a heavy block of wood that blocked the mouse from getting treats. he found that 8 out of 10 of the mice given special food were able to push the block away. 7 out of 10 of the mice given normal food were able to do the same.

Darrel conducted an experiment with the following procedure: fill two cups with ice water. place an uninflated balloon snuggly onto your left index finger. blow a little air into an identical balloon, and place it onto your right index finger. place both fingers into the cups of ice water. darrel noticed that his right finger felt warmer in the ice water than did his left finger. which of the following does the experiment show? a. air is a good radiator of heat. b. air is a good insulator of heat. c. air is a good conductor of heat. d. air is a good convector of heat.

Which scientific design has both practical limitations and limitations due to scale? studying the effect of bleach on the growth of mold spores exposing cultures of duckweed to different intensities of light observing the replication of dna molecules with a hand lens using colored marbles to model a cross between two colors of rabbits

The first generation of offspring from the cross of two parents is called the a.f1 generation b.f2 generation c.short generation d.p generation
