Essay 1: Light and Color The fascinating properties of light are not all detectable to humans‚ because our reference is mostly limited to what we can see. In order to determine the atomic/molecular composition of a fluid or gas‚ one must consult an emission and absorption spectrum. The properties of this spectrum include also waves‚ which can be any length‚ and define the spectrum of electromagnetic radiation. Ranging from gamma rays to radio waves‚ an electromagnetic spectrum includes each

The correlation between the occurrence of photosynthesis and different lengths of light waves. Introduction Photosynthesis is an exceptionally interesting process that is used by some organisms and plants. In the conversion of light energy from the sun to chemical energy that is used as food‚ photosynthesis is used for the everyday undertakings by some organisms and plants during their life span. This complex method of energy production is also represented by the equation: 6CO2 + 6H2O C6H12O6

The light reactions of photosynthesis contain two photosystems‚ two electron transport chains‚ and ATP synthase. These parts are embedded in the thylakoid membranes of a chloroplast. The photosystems contain a collection of chlorophyll molecules. Chlorophyll‚ which is the green pigment of leaves‚ absorbs light energy that excites electrons to a higher energy level. Energized electrons from photosystem I are passed down an electron transport chain and added to NADP+ to form NADPH. Electrons from photosystem

because blue light has a higher absorbance by plant photosynthetic pigments and has a higher energy wavelength than red light‚ we predicted that juniper needles placed in blue light would photosynthesize faster than juniper needles placed in red light. We measured the rate of change in CO2 concentration due to juniper needles. For each sample‚ we placed the needles into a chamber connected to the CO2 monitor and measured the rate of change of CO2 concentration for 10 minutes under red light and then

3.2 DNA Extraction The DNA will be extracted from the Nemipterus samples according to Wizard® Genomic DNA Purification Kit (Promega) protocols. The first step of is cells and nuclei will be lysed by adding 120 µl of 0.5 Molar ethylenediaminetetraacetic acid (EDTA) to 500 µL of Nuclei Lysis Solution in a eppendorf tube‚ then it will be chilled on ice until the solution turn cloudy. The second step is 0.5 cm of Nemipterus sample tissue will be minced to fine powder. The fine powder of fresh Nemipterus

Light Lab Report Introduction: Without light‚ plants would not be able to carry out photosynthesis (McKenney‚ Peffley‚ and Wilmington 49). Photosynthesis is responsible for providing the plant with nutrients it needs to thrive and grow. Without the proper nutrients‚ it is difficult for a plant to continue to live. Therefore‚ photosynthesis is necessary for a plant’s vitality. The goal of this experiment is to observe and identify the impact that light has on a plant. Hypothesis: If light

Lab: Cellular Respiration in Yeast Lab Report Form Your Name: Katlin Moore “What do you think? – What do you know?” Questions: In this lab‚ we will investigate the effect of sucrose concentration on the rate of cellular respiration in yeast. Under specific conditions‚ yeast will convert sucrose into glucose and then use this glucose in cellular respiration. Yeasts have been used by humans in the development of civilization for millennia. What is yeast? How have humans used yeasts?

Photosynthesis and Cellular Respiration lab makeup Photosynthesis absorbs energy from the the sunlight ‚and water‚and carbon dioxide to to create energy sugar ‚and oxygen. Photosynthesis also absorbs molecules that are called pigments. The process of photosynthesis is used by plants to make food for themselves. By then doing this‚ it also benefits us humans and animals by releasing carbon dioxide. Oxygen to them is considered a waste product‚ but a necessity to us. The photosynthesis

6CO 2 + 12H 2 O + light → C 6 H 12 O 6 + 6O 2 + 6H 2 O Introduction: In this simulation‚ you will be looking at the production of carbon dioxide as a plant photosynthesizes. Oxygen is measured in the number of bubbles produced by the plant. Three factors that influence the rate of photosynthesis can be adjusted in the simulator to determine how each of the factors affects the rate of photosynthesis.

images viewed through a light microscope Abstract: A compound light microscope uses two sets of lenses‚ ocular and objective‚ and employs light as its source of illumination. Through careful observation‚ we identified the various parts of a light microscope we found that the light microscope Ocular lenses which give 10x magnification power‚ and objective lenses which consist of three objectives: scanning‚ low power‚ and high power objectives. Then we observed under different magnification powers
