Nits, and control groups in the following studies. 1.
Mr. Smith wanted to see if the color of light shined on a plant had an effect on the number of leaves it had. He gathered a 2
groups of the same species of plants, gave them the same amount of water, and did the test for the same amount of time.
On one group of plants he used white light. On the second group he changed the light color to red. Identify:
Independent variable:
Dependent variable:
Constants:
Control group (What would Mr. Smith use as a control group?);
Experimental group (what would Mr. Smith use as a experimental group?)

the correct answer, according to e2020, is the second choice there is an occluded front in region a and a cold front in region b.

supercell thunderstorms are perhaps the most violent of all thunderstorm types, and are capable of producing damaging winds, large hail, and weak-to-violent tornadoes

transformative rocks are the stones that emerge from the transformation of existing rock composes in a procedure called changeability, implies changing of structures. transformative rocks are shaped from alternate shakes that are changing a result of warmth or weight connected. one of this model is the earth developments that making rocks profoundly cover or crushed which will make the stones warmed and put under awesome weight. they are not softening but rather the minerals they are containing are changed synthetically that will shape transformative rocks. now and again different rocks are shaped when the others are near some liquid magma and getting warmed.
