Consider a fictional organism called a gizmo that carries two copies of each chromosome like humans do Gizmos may carry two different variants of the a gene. Version A makes gizmos have solid-colored fur, while version a makes gizmos spotted. When examining the A versus a genes and the proteins that they encode, which of the following do we expect?

A. the gene sequences of both A and a are identical, but structures of protein differ.

B. the gene sequences of both A and a are different, but both protein structures are the same

C. the gene sequences of both A and a are identical, and both structures of protein are the same.

D. the gene structures of both A and a are different, and both protein structures differ

Which statements are true of a scientific theory but not a hypothesis

What is the relation ship between structure and function in an organism

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?
