The lysogenic cycle is beneficial to the reproduction of a bacteriophage because a. it quickly kills the bacterial cell b. it slowly breaks down the bacteria's immune system c. it causes the bacteria to become super-infectious to humans d. it allows the phage dna to be replicated during bacterial replication

Consider the model of the oxygen cycle on earth. the majority of earth's oxygen reservoirs are found in the a) atmosphere. b) biosphere. c) hydrosphere. d) lithosphere.

Sally and sue were investigating the topic of friction in science. they used a small car and a ramp as seen in the picture to test what they were learning. they knew that they slipped easily on waxed floors but not on carpet, so they decided to change the material on the surface of the ramp to see what happened. they planned to use glass, carpet, aluminum foil, and sandpaper and run the car down the ramp over each surface. what would be the best research question to guide the girls' experiment? a) does the amount of surface area affect the friction on the moving car? b) will the car travel fastest on the glass surface? c) how does the angle of the ramp affect the speed of the car? d)do rougher surfaces tend to create more friction than smooth surfaces?

Types of scientific inquiry that biologist engage in that cannot be completely controlled
