Scientist wants to see which type of liquid will make plants grow taller. The scientist gives three plants an equal amount of water, sunlight, soil, and amount of growing space. The scientist gives one plant soda, one plant milk, and one plant water. After a month the height of each plant is measured. What is the hypothesis, independent variable, dependent variable, constant variables, and control?

Is a  vector quantity  that refers to "the rate at which an object changes its position." imagine a person moving rapidly - one step forward and one step back - always returning to the original starting position. while this might result in a frenzy of activity, it would result in a zero velocity. because the person always returns to the original position, the motion would never result in a change in position. since velocity is defined as the rate at which the position changes, this motion results in zero velocity. if a person in motion wishes to maximize their velocity, then that person must make every effort to maximize the amount that they are displaced from their original position. every step must go into moving that person further from where he or she started. for certain, the person should never change directions and begin to return to the starting position.

Ithink it is letter b, i may be wrong but i think that is the answer

All are great precautions but you can still lift lighter and different muscles in between hard workdays. this keeps other muscles not usually used in shape.

Ibelieve the answer is arteries
