carol is doing a science fair project for her science class. she wants to investigate how the amount of water given to a plant affects its growth. she tests 30 plants and is careful to record how much water each plant gets. she also controls the type and amount of soil in each pot and the number of seeds in each pot. she uses 1 cup of water each day for her control group, giving 1 cup of water to ten plants and she gives 2 cups of water to ten plants, and 3 cups of water to ten plants. whe it is time to present her project, she concludes that the plants getting 3 cups of water a day grew better than the control group that received 1 cup of water a day or the plants receiving 2 cups of water each day. which additional piece of information is most important to include if someone wants to reproduce carol's experiment

answer and explanation;

volcanic rocks are igneous rocks which form from lava, molten rock which has been thrust out of a volcano onto the surface of a rocky body such as an asteroid, planet, or dwarf planet.  

plutonic rocks are igneous rocks which form from subterranean chambers of molten rock or magma. plutonic rocks make up the base of continental crust as well as oceanic crust. their slow rate of formation causes them to be coarse grained since there is plenty of time for large crystals to form before the magma solidifies into rock.

the textural difference is that plutonic rocks are more coarse grained than volcanic rocks. plutonic rocks are coarse grained while volcanic are fine grained ; glassey or fragmental. since fine and coarse are adjectives the decision as to whether a rock is fine or coarse grained is generally made on the bases of whether or not the individual crystals can be seen in most if the rock.
