Describe the role of photosynthetic organisms

William notices that a group of ivy plants growing in a cool room of a building grow at a different rate than a group of the same kind of ivy growing in a warm room in the same building. He wants to find out why the two groups of plants grow at different rates. How could he carry out an experiment using all of the steps of a scientific process? Please explain.

Please describe the role of photosynthetic organisms, such as plants, in converting the energy of light to energy that can be used by all living things including the photosynthesizers themselves.

A pet store has two guinea pigs. One has white fur and one has black fur. The white guinea pig has two recessive alleles for fur color (bb). The black guinea pig has one dominant allele (B) and one recessive allele (b) for fur color. What will most likely be the phenotypes of the offspring in a cross between the two guinea pigs? Explain, please.

What are the basic parts of a major theme in molecular biology: the pathway of DNA to RNA to proteins? Please reference a brief summary of what occurs at each stage.
