Plant Pigments and Photosynthesis Problem: We are going to separate and identify pigments and other molecules from cell extracts through a process called chromatography. We will also test the theory that light and chloroplasts are required for light reactions to occur. Background: Pigments are chemical compounds which reflect only certain wavelengths of visible light. This is what makes them seem colorful. Many things contain pigments including flowers‚ corals‚ and even skin. More important than

Book Write Up The novel Your Inner Fish‚ by Neil Shubin‚ shows profound knowledge of evolution in the origins of the humans. Shubin writes enthusiastic chapters that specify major organs of general life on earth‚ ranging from aquatic life like sharks to terrestrial animals such as mice. Shubin skillfully explains complex connections to us humans to other present animals with evidence‚ in fossils‚ that show evolution throughout millions‚ even billions of years. How did we inherit all those

In my BIO 102 lab I have learned about the Microscope and Lab Safety‚ Sensory Organs (Eyes and Ears)‚ The Human Blood and Circulation‚ and Respiration. Once I first started this class this semester taught us about the Microscope and Lab Safety. According to google online dictionary a Microscope is an optical instrument used for viewing very small objects‚ such as mineral samples or animal or plant cells typically magnified several hundred times. We used this instrument to look at different types

AP Bio Lab Report Osmosis and Diffusion Introduction When a substance is released into an area‚ the random movement of its molecules results in a multitude of collisions. These collisions‚ in turn‚ lead to a dispersion of the molecules. The overall movement of the molecules will be from an area of high concentration‚ where there will be more collisions‚ to areas of low concentration‚ where the number of collisions will be much less. This process of dispersion will continue until there is no
