You have isolated two mutants in a tomato, one is true breeding for yellow fruit (red is wild type), and the other is true breeding for dwarf plants (tall plants are wild type). You suspect these two traits sort independently. After crossing both the true breeding parents, the F1 generation are tall plants with red fruit. You self that F1 and obtain the following progeny numbers: Red, tall - 185
Red, dwarf - 100
Yellow, tall - 56
Yellow, dwarf - 33
Are these numbers consistent with genes that sort independently? Statistically justify your answer.

What is the following best defines climate?

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?

Which of the following produces carbon dioxide? a. plants b. animals c. decomposers d. all of the above
