Suppose that you have just graduated from college and have started working at a biotechnology firm. your first job assignment is to clone the pig gene for the hormone prolactin. assume that the pig gene for prolactin has not yet been isolated, sequenced, or mapped; however, the mouse gene for prolactin has been cloned, and the amino acid sequence of mouse prolactin is known. briefly explain two different strategies that you might use to find and clone the pig gene for prolactin.

Describe pasteur’s results and how they disprove spontaneous generation.

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?
