Plants respond to their environment in many different ways. Design an experiment to test the effects of temperature on the plant growth. 1. state on hypothesis the experiment would test 2. state how the control group would be treated differently from the experimental group 3. state two factors that must be kept the same in both the experimental and control group 4. identify the independent variable 5. identify the dependent variable

they fuse to form they have half as many chromosomes as a somatic cell of the same individual. b

the correct answer is 4) heat and pressure

metamorphic rocks arise from transformation of existing rocks types, in a process called metamorphism. during metamorphism the original rock(prolith) change into metamorphic rock by heating (150-200c) and pressure of more than 1000 bar. the original rock can be sedimentary, igneous, or existing metamorphic rock.
