Conservation practices . may cause yields to increase and therefore provide more fish will cause yields to decrease and therefore conserve fish will cause yields to remain constant for many years created a commission to study fish biology

If you have a difficult time knowing where your hand is without looking at it you may be having a problem with your what ?

Of seawater increases with decrease in the temperature. therefore, the cold water sinks to the deeper layers at the bottom

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?
