Explanation:
Reproductive isolation is where a species can't breed with any other species except its own.
No, because a single observation on one planet is not sufficient to discredit a theory.
There are too much variables that would cause that data, and just observing one planet is the same as ignoring all the potential variables.

Answer:
D. Toy pulls on the child in the opposite direction
Explanation:
Newton third law of motion states that for every action, there is an equal and opposite reaction. This means that whenever an object 1 exerts a force (action force) on another object 2, object 2 exerts a force (reaction force) of equal magnitude but opposite direction on object 1.
According to this question, a child pulls a toy across the floor. Based on Newton third law described above, the toy will pull the child with an opposite force that is equal in magnitude. Hence, the equal and opposite force is: Toy pulls on the child in the opposite direction.
