Which procedures were followed in this lab to decrease experimental error? check all that apply. using only two types of seeds, both from the same source having one student count every sprout in every quadrat using adjacent plots of land for both groups increasing the sample size by combining data from multiple groups repeating the experiment indoors under growth lights measuring plant height the same way and at the same time for both groups

Explanation: I got it right on edge

explanation:

the universal gravitation equation. since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force. if the mass of one of the objects is doubled, then the force of gravity between them is doubled.
