The Effect of Distance from Light Source on the Rate of Photosynthesis Introduction: The effect of distance from the light source on the rate of photosynthesis was tested in this experiment. This was tested to find ways to accelerate the rate of photosynthesis. If plants are placed closer to a source of light‚ then their rate of photosynthesis will be higher because they are receiving more light. Experimental Design: The independent variable is the distance of the beaker from the light source

Transpiration Formal Lab Report By Jessica Tran Introduction When water is transported from the roots to the mesophyll cells in the leaves‚ it is evaporates out the stomates‚ called transpiration‚ to create a lower osmotic potential. Osmotic potential is the part of the water potential of a tissue that results from the presence of solute particles. Even though the stomates open to release water‚ it also brings in carbon dioxide to produce sugar and oxygen through a process of photosynthesis

BIOLOGY LAB REPORT (UNIT 7: ENZYMES) GENERAL Enzymes are protein that acts as catalyst‚ lowering the activation energy need for reactions to progress in cells. The reaction can still occur without the presence of the enzyme‚ but at a much slower rate. The activation energy is the minimum amount of energy need for a chemical reaction to occur‚ yielding from a given set of reactants. In enzymatic reactions‚ we have substrates which are reactants of reaction bound to an enzyme. While an active site

Introduction Human cilia play a critical part in human processes. Human cilia are hair-like projections that extend from the surface of a cell. Cilia are capable of rhythmic motion and acts together from separate strands so that the cell is capable of movement. Flagella are a whip-like structure that is found in cells as well that allow for the movement of the cell. Human cilia are characterized as having “metachronal rhythm" and this means is a rhythm that "changes time" to produce wave. The beating

6 November 2012 SUBJECT: Lab Report Analysis This memo proposes the observations and claims I collected from reviewing three different lab reports. Three fields of study are composed within this memo that includes Electrical Engineering‚ Environmental Engineering‚ and Petroleum Engineering. “Electrical Filters‚” (Electrical)‚ written by Joe Schmoe‚ is a lab report made by a student at a university. The College Board produced an environmental lab report named‚ “Monitoring Air Quality‚”

Tenen Lab: Thursday (3-6 pm) OSMOSIS LAB REPORT INTRODUCTION Osmosis is a special type of diffusion where water molecules move down a concentration gradient across a cell membrane. The solute (dissolved substance) concentration affects the rate of osmosis causing it either to speed the process up or slow it down. Based on this‚ how does different concentrations of sucrose affect the rate of osmosis? If sucrose concentration increases in the selectivity-permeable baggies‚ then the rate of osmosis

Topic Basal Cell Carcinoma Background Basal Cell Carcinoma is a type of cancer that grows on your skin. This type of cancer tends to grow on skin in places that have had a lot of exposure to the sun. Basal Cell Carcinoma is actually one of the least dangerous types of skin cancer. Basal Cell Carcinoma is usually very easy to catch and is easy to treat. “The tumors start off as small shiny bumps‚ usually on your nose or other parts of your face” (WebMD). They can appear on any part of the body but

Acute insulin response (AIR) level was calculated‚ which is actually average increase of insulinemia relative to basal value in the first 8 min of IVGTT‚ with the following equation:

Sea Otter Metabolics and Thermoregulation Sea Otters (Enhydra lutris) have always intrigued me because they are one of the most recent additions to the marine environment having only been fully aquatic for about 1-3 million years‚ but what really peaked my interest was the fact that they maintain homeostasis as far north as Alaska without blubber in 13-17 degree water‚ and that the metabolic rate that they would have to have must be enormous so I decided to look into what it takes to keep an

[Name] [Teacher] [Course] [Date] Catalase Lab Report An enzyme is something that helps to speed up a chemical reaction. The enzyme changes from reaction to reaction‚ but it always has the same impact. However‚ certain variables may cause the enzyme to have a more or less significant impact on the speed of each reaction. One of these variables that changes the effectiveness of an enzyme is temperature. There is an optimal functioning temperature for each enzyme in each reaction‚ depending on
