Which of these events occurs during DNA replication? DNA polymerase synthesizes a complementary strand from one, but not both of the original
strands.
DNA polymerase synthesizes a complementary strand from each of the original strands.
DNA ligase breaks apart one of the original strands, and other enzymes re-assemble the
components into a new strand,
DNA ligase breaks apart both of the original strands, and other enzymes re-assemble the
components into two new strands.

Which type of bacterial reproduction is depicted in the diagram?

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?

This class has taught you that the use of science and medicine in practical ways has become an international endeavor. one of the greatest examples of an international science accomplishment is which allows the profiling of human dna, useful not only to science but also medicine. a) forensic science b) the fbi c) the human genome project d) bioterrorism
