    In this lab we are going to be observing the decomposition of piglets over a month’s time. There are theory questions that have been given to us before and after the lab. We look back at our original theory to see where we went wrong‚ and then correct it. The lab was disgusting‚ surprising‚ and very interesting. The first questioned to be answered is which piglet decomposes faster‚ a piglet that is in its natural state‚ that is burnt‚ that is buried‚ and that is buried in a wooden box? With

    Varied light intensities can alter the photosynthetic capability of chloroplasts. As light intensity increases‚ it is apparent that the rate of photosynthesis begins to decrease until a certain level of light saturation. If the intensity extends over a certain tolerance level‚ photo inhibition occurs. The light used for photosynthesis requires a specific wavelength for the pigments in chloroplast to absorb it. Light independent reactions occur in the stoma of

    Abstract: The Enzyme Lab results where when the liver was frozen‚ its reaction was fast‚ and when it was hot‚ it was slow‚ and the liver that was at room temperature reacted slowly to medium. Introduction: The Enzyme Lab is to conduct investigations to determine the most favorable conditions for the most efficient enzyme activity. Variables to be used testing include temperature‚ pH values and surface area. Enzymes are proteins that speed up the rate of chemical reactions‚ which would otherwise

    Derricka Joe Period 5 1 Oct.‚ 2014 Lab Experiment One: Physical Properties Lab Analysis: For our first unknown‚ we observed the color and odor of the substance. The substance was a clumpy‚ white‚ crystal-like substance and it smells like new plastic. When we tested the solubility in water it resulted insoluble and in ethanol it resulted soluble. This substance could not be tested for electrical conductivity because the water was insoluble. We then tested for the PH value and it was neutral. The

    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

CNB are believed to be the agents of autotrophic origin of life thus they probably represent the survivors of the earliest photosynthetic plants‚ along with photosynthetic and chemosynthetic bacteria. CNB fossilized remains have been found in middle Precambrian rocks‚ and they may have appeared much earlier (Humm and Wicks 1980). b.
