Bob is investigating two leaf samples. He views a leaf sample taken from a desert plant under
the microscope and notices that the stomata are all closed. He then views a leaf sample taken
from the rainforest and notices that most of the stomata are open. What is the most likely
explanation for the differences that Bob sees between the two leaf samples?
Due to the differences in climate, desert plants need to conserve more water than rainforest plants.
Due to the diffences in climate, desert plants do not need to grow as quickly as rainforest plants.
Due to the differences in climate, desert plants do not need to exchange gases as efficiently as rainforest
plants
O Due to the differences in climate, desert plants do not need to reproduce as often as rainforest plants.

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?
