Kepler's 1st law: law of ellipses stationary objects resist movement, and moving objects resist stopping. 2. kepler's 2nd law: law of equal areas the greater the mass, the stronger the gravitational force. the greater the distance, the weaker the gravitational force. 3. kepler's 3rd law: harmonic law acceleration of an object depends on its mass and applied force. 4. newton's 1st law of motion an imaginary line joining a planet to the sun sweeps out equal areas in equal amounts of time. 5. newton's 2nd law of motion planets closer to the sun orbit it in a shorter time period than planets further from the sun. 6. newton's 3rd law of motion the orbit of planets is not circular but elliptical. 7. newton's law of universal gravitation for every action, there is an equal and opposite reaction.

Clara wrote the following hypothesis for an experiment about acidophilic bacteria. bacteria cells will stop dividing in a basic (alkaline) environment because of the high ph. which statement is the best way to restate the hypothesis so that it is more specific? growing acidophilic bacteria in some environments will cause the cells to stop dividing because of ph. if the ph of their environment is changed, acidophilic bacterial cell division will be affected. if the environment of acidophilic bacterial cells becomes alkaline, the bacteria will stop dividing. the more alkaline an environment, the less cell division will occur in bacteria.
