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.

Please help :)

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.

a corroding iron, if that's one of your choices

the cold front replaces the warmer air at the ground level changing the wind to be breezy and denser.there is also an immediate drop in the temperature.
