6. You design an experiment in which you investigate it different types of fertilize atteet tomato plant height. You prepare 4 plots of soil, all containing tomato plants. To the first
plot, you add a potassium fertilizer. To the second pict, you add a nitrogen fertilitet To
the third plot, you add a phosphate fertizer. You do not add any fertilizer to the fourth
plot You eventually gather data by measuring the height of each tomato plant,
B. What is the independent variable?
C. What is the dependent variable?
D. What type of data are you gathering qualitative or quantitative!

A where is question A?

B types of fertilizer

C plant height

D quantitative

the control is no fertilizer

& what is the null hypothesis?

explanation:

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.
