Gregor Mendel studied pea plants to determine the patterns of inheritance. What is not a reason Mendel used pea plants in his experiments? Check all that apply.

They reproduced sexually.

They were drought resistant.

They had traits that were easy to observe.

They only had two traits to study.

looks like the answer is     c     to me!

igneous rocks are formed by solidification of cooled magma (molten rock), with or without crystallization, either below the surface as intrusive (plutonic) rocks or on the surface as extrusive (volcanic) rocks.  

the composition depends on the source magma. there are almost a thousand types of composition found till now.  

hope this

the sun's light combined with the visible wavelenghts form what is called ultraviolet radiation, which are the long waves at the end of a visible light sprectrum.
