Jane is a patient. her brother greg has neuronal ceroid lipofuscinosis, also known as batten disease. it is autosomal recessive, and its symptoms include vision loss, loss of coordination, dementia and seizures. jane is healthy as are her parents and grandparents. jane is thinking of having children. she wants to know what the probability is her child would be a carrier for batten disease (in other words, the probability that jane is a carrier and that her child will inherit the recessive allele). since batten disease is very rare, we will assume that the father of jane's child is not affected nor a carrier.

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?

Drag each label to the correct location in the equation. not all tiles will be used. the density of mercury is 13.6 grams per cubic centimeter. complete the steps for converting 13.6 g/cm3 to kg/m3. (1 kg = 1,000 g, 1 m3 = 106 cm3)
