After four divisions, the zygote becomes a morula- the stadium that consists of 16 blastomeres. By the fifth day of development the form of the blastocyst is formed through the processes of compaction, cell division, and blastulation. Later, specialized cells in the embryo are derived from the inner cell mass (ICM) of the blastocyst.

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?
