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

A series of 250ml Erlenmeyer flasks containing 100ml of M1 medium (0.2g NaNO3‚ 0.05g KCl‚ 0.05g MgSO4.7H2O‚ 1g glucose‚ 0.001g FeCl3‚ 0.02 g BaCl2‚ 0.05g CaCl2) at pH 6.8 with an addition of increasing concentration of deltamethrin was prepared. 1ml of 108 fungal spore suspension cultures was added into each of these flasks. These flasks were incubated at 280± 20C on the shaker at 120rpm for 7 days. Mycelium growth

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:

Organismic Lab Lab1- Dichotomous Key Introduction A dichotomous key is a series of paired statements or questions that are used to categorize organisms with their similarities in characteristics and or structure. The word dichotomous comes from two Greek words that translate to “divided in two parts.” In a Dichotomous key each step has two choices: whether a particular characteristic is present or absent. The questions

et al Abstract: The purpose of this lab was to determine how light affected photosynthesis‚ specifically the production of O2 bubbles. It was predicted that when the light was more intense the O2 bubble production will be high. Conversely‚ when the light was less intense the O2 bubble production will be lower. Basically the plant that is closer to the light will produce more bubbles than the plant that is placed farther away from the light source. In this lab the independent variable is the light

Lab Report 6: Respiratory Physiology Purpose: To describe the effects of carbon dioxide concentration on blood pH. Hypothesis: If the blood CO2 levels increase‚ the pH will decrease. Materials and Procedures: Materials: Willing subject (someone complete the activities of the experiment) Timer (with a second hand) Glass Urinary and Salivary pH (litmus) paper Drinking straw Procedures: 1. Measure 2 ounces of water in a glass. Obtain the pH of the

Carbohydrate Lab Report Introduction Qualitative identification of a substance is of significant importance in chemistry. Physical constants such as melting points have traditionally been used by organic chemistry for identification of unknown compounds. As for inorganic substances‚ the precipitation of a solid‚ results of a flame test‚ or the formation of a colored substance could all be keys to identifying a sample. Chromatography and spectra are amongst the newer techniques

Quantifying the COX1 Gene within the Mitochondrial DNA of a Potato Introduction Respiration is a very important process for every living organism. While it is typically thought of as breathing in oxygen‚ and exhaling carbon dioxide‚ like all things‚ it must take place at the cellular level. The electron transport chain is responsible for cellular respiration. The process uses four complexes; the fourth is cytochrome c oxidase. Cytochrome C oxidase is responsible for the reduction of oxygen to water
