Imagine that certain laws of physics could be ignored and you were able to travel vast distances in moments. Now imagine that you traveled to an Earth-
like planet located light-years away that is known to support life. Think about
what you've learned in this unit and make an argument for what you think
would be the dominant type of life form on this planet. Consider whether a
notochord is required for an organism to manipulate its environment and
become a dominant creature.

What is the importantence of the carbon and nitretan cycles in the environment

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?

Dna. we have heard that we are a product of our dna. but where is it? how do we "get" our dna? it is passed to us, from our parents, but in what form? several vocabulary words associated with inheritance are used interchangeably and sometimes, incorrectly. let's see if you can clear this up for someone just learning about inheritance and cell structure.
