In this exercise, you will compare the amino acid sequence from the aphid to the amino acid sequences of the other species to identify how similar they are. as a first step, you will compare the aphid sequence (acyrthosiphon) to a bacterial sequence (pantoea).

the sequences below show the first 60 amino acids of one polypeptide, using the one-letter abbreviations for the amino acids. an underscore indicates a gap inserted in a sequence to optimize its alignment with the corresponding sequence in arabidopsis.

acyrthosiphon (aphid) knsynggrcs ihr_hnghrf dqgpsl__yl
pantoea (bacterium) qhdkpggray vwq_dqgftf dagptv__it

at how many positions are the amino acids the same between the two species?

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?
