# Now You See It – Copper Cycle Lab The purpose of the lab is to discover what happens when someone executes a series of procedures‚ beginning with copper metal. What is done | What is observed | 1. Started with copper‚ Cu (s). | reddish‚ brownish‚ orange-ish‚ powder-like | 2. Added nitric acid‚ HNO3 (aq). | acid turns blue and smells like chlorine. | 3. Added water‚ H2O (l). | stayed the same | 4. Added sodium hydroxide‚ NaOH (aq). | changed consistency‚ gel-like | 5. Heated the

The protein concentration in bovine cells was measured by diluting the homogenate with a 1:5 ratio; 50 microliters of homogenate and 200 microliters of water. Then 5 known protein concentration samples which were 0.4‚ 0.8‚ 1.2‚ 1.6‚ 2.0 mg/ml of bovine serum were used to

"The Ransom of Red Chief" (1910) * “Calloway’s Code” SYNOPSIS Johnsy and Sue are artists who moved into Greenwich Village in New York City. As Winter approaches and the weather gets colder‚ Johnsy becomes ill with pneumonia. She gets so sick that she believes that when the last leaf falls from the vine outside her window‚ she will die. An old artist‚ named Behrman‚ who lives in the same building as the girls‚ braves a storm one night to paint a leaf on the wall — a leaf that will never

amount of nutrients available; nitrogen‚ phosphorous‚ and potassium are three very essential nutrients that collectively aid in photosynthesis‚ growth‚ formation of proteins‚ and overall quality of the plants. Not having these essential nutrients may result in various diseases‚ leaf discoloration‚ and very limited growth. In our experiment we decided to test how exposure to sunlight (or lack thereof)‚ and the amount of nutrients available to plants affect seed germination as well as overall plant growth. We did this by exposing some plants to light while others not

The Charge/Mass (e/m) Ratio of the Electron PHYS 0212: Introduction to Laboratory Physics Fall 2012 Abstract The experiment conducted demonstrated correlation between the charge and mass of an electron and the behavior of magnetic fields. The lab was divided into four parts. The first three parts were conducted with a compass that was used to locate the magnetic field lines around a bar magnet‚ a solenoid and then a pair of Helmholtz coils. As a result of these trials‚ our observations found

THE LAST LEAF SCENE ONE NARRATOR: In New York City‚ there’s a small district just west of Washington Square‚ where the narrow‚ irregular streets have run crazy and broken themselves into short strips called places. It’s an ancient‚ residential community where many of the beautiful‚ old‚ brick houses date back to the 1820’s‚ when an epidemic forced people from the city to what was then a rural suburban village. Now‚ in the final year of the nineteenth century‚ we find clusters of colorful restaurants

Wave Nature of Light Objective: The purpose of this lab is to investigate interference‚ otherwise known as the diffraction of light. A beam of light acts a wave‚ and we are able to use equations so calculate the wavelength of the light used. The diffraction of a straight edge demonstrates that light waves bend around straight edges‚ allowing light to enter an area of shadow. When waves are superposed‚ they reinforce each other when crests are in phase and cancel out when they are not in phase

LSM1102 Lab Report Introduction Transformation is a process which involves plasmid DNA being bound to the cell surface and the subsequent uptake of DNA by the cell (Panja et al.‚ 2008). For artificial transformation of E. coli cells with plasmids‚ plasmid DNA has to be extracted from bacterial cells using the High-Speed Plasmid Mini Kit‚ which is then mixed with competent E. coli cells followed by heat shock and the streaking of transformed cells on two different types of agar plate (LB and LB+ampicillin)
