Answer:
color of light
Explanation:
<em>The independent variable is the variable that is supplied and often varied/manipulated by the researcher during the course of experiments. It is varied/manipulated in order to see the effect it will produce on another experimental variable - the dependent variable.</em>
In this case, out of all the variables supplied by Mary, only the color of light supplied was varied - red, white, green, and blue; other variables supplied were kept constant. Hence, <u>the independent variable is the color of light.</u>
<h2>Answer:</h2><h3>Lilies do best in a position of full sun, ideally with their roots in rich and fairly moist, yet free-draining soil or compost. Grow oriental lilies in acidic soil or ericaceous compost, and Asiatic lilies in neutral to alkaline soil or multi-purpose compost and not in gardens because most Garden soils are made from three main components: clay, sand and silt. The ideal soil (or loam) has equal amounts of all three, making a fertile soil that is free draining and easy to dig.Which are nothing but making the sand more rougher.So therefore those lillies will not grow in the garden soil and that is the reason why the lillies never grew</h3><h3 />
