Photosynthesis Lab Report Purpose: To research the effect of different wavelengths (colors) of light on plant growth during photosynthesis. Background Information: Photosynthesis is the process by which sunlight is captured by chloroplasts within plant cells and turned into energy. This energy is used to help the plant grow roots‚ leaves‚ flowers and fruit. Energy is required by living things

Purpose The purpose of the “Beanium” lab was to determine the average atomic mass of three different isotopes of beanium. During the lab beans were counted to determine mass of the sum of the beans. Each type of bean were weighed separately and then averaged together to determine the average atomic mass of beanium. Materials and Hazards Analytical balance‚ coffee filter‚ pencil‚ paper‚ cup‚ American beans‚ Nigerian beans‚ Mexican beans‚ calculator‚ and paper. Raw Data Bean Total Mass w/ Cup Number

than the actual melting point of pure aspirin; 135°C. The phenol test showed that the product is not a pure aspirin by expressing purple color. TLC results weren’t high enough to conclude that the product was a pure aspirin. Overall‚ the lab wasn’t successful due to the low percentage of aspirin that were produced. Out of 2.0 grams of aspirin‚ only 0.7862 grams of pure aspirin were produced. So the percent yield was only 39%. Errors could be made during filtration process and the melting of the aspirin

turn off the primary production. Darkness has no effect on respiration. This is because cellular respiration is actually the reverse process of photosynthesis. Oxygen is a necessity of life requirements for basically all living organisms.* In this lab we are testing how different levels of salinity in the water indirectly affects the gross primary productivity in aquatic plants. To measure this you would use the light and dark bottle method. Only respiration (R) can occur in the bottle stored in

Abstract This lab is performed in order to determine the total energy in a reaction between zinc and hydrochloric acid. The reaction is done twice‚ once to measure the heat of the reaction and again to determine the work done in the system. This is because Enthalpy equals heat plus work (∆H= ∆E+W). Heat and work can be broken down further into separate components so the equation used in lab is ∆H=mc∆T + PV. Many calculations are used in the lab to find out what cannot be measured directly (ex:

Title: Confirming the Presence of Fermentation in the Conversion of Milk to Kefir Authors: Michael Ahrens‚ Nicholas Fiore‚ Garrett Hages‚ Melissa Cullom University of Kansas‚ Biol 402‚ Fall 2014‚ 3:00pm room 6040 Abstract: In this experiment milk was fermented into Kefir‚ then a series of tests were used to confirm that fermentation actually occurred. The tests used to confirm the fermentation were a gas production test‚ pH test‚ Gram stain‚ and turbidity test. The results showed during the conversion

Meiosis and Genetic Diversity in Sordaria 979554296 Biology 110 Lab Introduction: In Israel there exists multiple spots in the mountains called Evolution Canyons‚ which are all located between a southern facing slope (SFS) and a northern facing slope (NFS). What’s particularly interesting about these locations is that despite the two slopes being on opposite sides of a small canyon‚ they exhibit extremely contrasting conditions. The SFS receives multiple times the UV radiation from the sun

Sudden Acceleration An automobile accident involving a Lexus (subsidiary of Toyota) vehicle resulted in the deaths of four people in California on August 28‚ 2009. Mark Saylor took his car into the Bob Baker Lexus dealer in El Cajon‚ CA to have it serviced and they provided him a loaner 2009 Lexus. While Saylor was driving the Lexus loaner it suddenly accelerated and he couldn’t control the car. One of the three other occupants in the car called the police on their cell phone to report that
