7. Some multicellular and single-celled organisms have been recently discovered around Lake Jackson Georgia. Scientists observed that some of the organisms produce sexually, a few
asexually and the organisms shared similar characteristics. For example, they all are eukaryotic
but do not have specialized tissues and some have plant-like characteristic while other have
animal-like characteristics. To what kingdom does the organism most likely belong? (57L1a)
A. Kingdome Plantae
B. Kingdom Protista
C. Kingdom Fungi
D. Kingdom Animalia

According to the cladogram, which organisms have roundworms as a common ancestor?

What is the next step in muscle contraction after the actin changes shape? (apex)

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?
