From the drop-down list, choose the flaw for the given scientific design.

A student wants to determine how well tulips will bloom at high temperatures. She knows they bloom well at room temperature, so she sets up groups at higher temperatures: 80°F, 90°F, and 100°F.

nah.   i'm just sleepy.

does anyone know or what?

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.
