a. igneous
b. metamorphic
c. sedimentary
d. fossils are found in several of the types listed above

D. is the correct answer. fossils are found in several of the types listed above and we know this because  simply the discovery of them is all random, and you can, for example, find a fossil of a dinosaur in igneous and then find a pre-cursor to the dinosaur.

Plant growth with different colored Lights. The purpose of this experiment is to find out if plants grow better a certain color light. It was thought that the green light would cause the plant to grow faster since it is a green plant. ... There was a tie between the plant under the blue and white light.

1. Make a hypothesis about which color in the visible spectrum causes the most plant growth and which color in the visible spectrum causes the least plant growth? If red and blue are absorbed more by the plant then red and blue will be the most effective and green will cause the least plant growth.

Plants use the food they make for growth and for other life processes. Sunlight is the natural energy source for photosynthesis. White light from the sun is a mixture of all the colors of the visible spectrum: red, orange, yellow, green, blue, indigo, violet.
