The following statement is a hypothesis formed about marsh grass:
If the amount of nitrogen marsh grass receives is increased, then the height of the grass will increase, because nitrogen is an essential nutrient needed for marsh grass to grow.
What is the independent variable of the statement above?
If the amount of nitrogen marsh grass receives is increased, then the height of the grass will increase, because nitrogen is an essential nutrient needed for marsh grass to grow.
What is the independent variable of the statement above?
a)
Height of grass
b)
Amount of nitrogen
c)
Essential nutrient
d)
Amount of growth
12.
The following statement is a hypothesis formed about marsh grass:
