Meiosis is a life process associated with sexual reproduction. Which choice correctly summarizes meiosis into one statement? O Haploid cells join and produce diploid daughter cells.
O Chromosomes in a haploid cell are pulled apart, creating two haploid daughter cells,
O Chromosomes in a diploid cell uncoil and line up, creating two diploid daughter cells.
Homologous chromosomes in a diploid cell separate and produce four haploid daughter cells.

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?
