Scientific experiments are specially designed to test explanations for an observed phenomenon. a student decides to conduct an experiment to determine the effect that the amount of time spent in the sunlight has on the overall growth of a plant. the student will conduct the experiment using two identical plants that will only spend different amounts of time in the sunlight. all other aspects needed for growth will remain identical for each. in the experiment described, what would the amount of water given to each plant be considered?
a.
an observation
b.
a dependent variable
c.
an independent variable
d.
a control or constant
select the best answer from the choices provided
a
b

Interpret the model. a three-part model with black right-arrows between the parts. left part: a large green apple-shaped component with a w-shaped indentation centered on top. a small blue apple-slice shape sits above the left indentation and an arrow points from the shape to the indentation. a small purple apple-slice shape and arrow sit above the right indentation and an arrow points from the shape to the indentation. middle part: a large green apple-shaped component with a square indentation centered on top. sitting in the left side of the indentation is a blue apple-slice shape with a flat bottom, fused to a purple apple-slice shape with a flat bottom on the right side of the indentation. right part: a large green apple-shaped component with a w-shaped indentation centered on top. an up-arrow is centered above the indentation pointing to a fused blue and purple apple-slice-shaped flat-bottom component sitting above the indentation. assigne "true" or "false" to the end of each statement. the model shows a shape change occurring in the enzyme after the substrate is bound in the active site. t/fthere are two products in this model. t? f there are three substrates in this model. t/f the model shows two different enzymes. t/f
