The cells of one rose bush have been dying quickly and in large amount recently. A botanist designs an experiment to test what is causing this problem. She discovers that one of the organelles is allowing hazardous pesticides to enter the cell. These toxins are not being dissolved quickly enough, and wastes are not being released in large enough quantities. Which TWO organelles does the botanist now know to extract and test for genetic abnormalities

Which animal group is the largest and contains more species from all the other living groups combined? is it mammals or

Why is a dominant allele called dominant

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?
