What is balanced and unbalanced force
I'm not changed, I'm just improved

forces that are equal in size and opposite in direction. Balanced forces do not result in any change in motion. unbalanced. forces: forces applied to an object in opposite directions that are not equal in size. Unbalanced forces result in a change in motion.

600 tall pea plants.

Explanation: The F1 generation must be all tall pea plants, if in the F2 generation there are 200 short plants that is the 25% of the offspring, the tall plants must be the 75% of the offpring, that is 600 (3 simple rule):

200 ----> 25%                 X= (75% x 200)/ 25% = 600

  X ------> 75%
