Which statement correctly describes the difference between meiosis i and meiosis ii?
meiosis i results in two haploid (n) daughter cells, each with half the number of chromosomes as the original cell. meiosis ii results in four haploid (n) daughter cells.
meiosis i
prophase i- synapsis occurs (each pair of chromatids joins its homologous pair and forms a tetrad) (group of 4 chromatids); recombination occurs ("crossing over", pieces of tetrad twist around and exchange segments
metaphase i- tetrads line up along the equator of the cell
anaphase i- non-disjunction occurs- chromosome pairs separate
telophase i- cells divide and 2 haploid daughter cells are formed
meiosis ii
prophase ii- chromosomes move toward the middle of the cell
metaphase ii- chromosomes line up at the equator
anaphase ii- chromosomes separate into chromatids
telophase ii- both daughter cells divide and 4 haplod cells are formed

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?
