The protein molecules in many foods provide the amino acid building blocks required by our own cells to produce new proteins. To determine whether a sample contains protein, a reagent called Biuret solution is used. Biuret solution contains copper ions. However, the chemical state of the copper ions in Biuret solution causes them to form a chemical complex with the peptide bonds between amino acids (when present), changing the color of the solution. Biuret solution is normally blue, but changes to pink when short peptides are present and to violet when long polypeptides are present.

There are many reasons for identifying an unknown bacterium. The reasons range from medical purposes, such as determining if the unknown could cause ailments in living things or knowing what microorganisms are needed to make antibiotics. The experiment was done by applying methods in order to identify an unknown bacterium.

3. Experiment: Use the Gizmo to find the carrying capacity with Ample, Moderate, and Little land. List the carrying capacities below.

8. (a) Assuming than no water vapor is added as the parcel descends down the lee side of the mountain to sea level, is the water vapor content (the mixing ratio) of the parcel higher or lower than before it began to rise over the mountain?

1. During gym class, four students decided to see if they could beat the norm of 45 sit‐ups in a minute. The first student did 64 sit‐ups, the second did 69, the third did 65, and the fourth did 67.

Submit your document in a Word (.doc or .docx) or Rich Text Format (.rtf) for best compatibility.

6) Now click on ‘Circular’ on the bottom. Describe the motion of the ball and the behavior of the two vectors. Is there a force on the ball? How can you tell? Be detailed in your explanations.

In the second experiment, I filtered water in a similar matter as to how water is properly filtered in order to purify it to drink it. The materials used in this experiment were 100 mL potting soil, beakers, 40 mL sand, 20 mL activated charcoal, 60 mL Gravel, alum, bleach, cheesecloth,

A lab write up can make or break your results in the science world. Structure is very important. The article “Materials & Methods” is basically a step by step how to guide for anyone learning how to write a lab report.

Enzyme Kinetics and Protein Determination: How Enzyme Catalase Concentration Affects Reaction Rate and Determining the Identity of Unknown Proteins through Absorbance

The exposed roadcut east of the Doc Long Picnic area, about 9 miles north of the town of Cedar Crest on the east side of the Sandia Mountains, provided an exceptional site to study weathering processes. The exposed Precambrian Sandia Granite offered a place to collect data and test the hypothesis that biotite content, grainsize, and associated inclusions have influenced the amount of weathering that has occurred. The granite underlies the “Great Unconformity” and the Madera Formation, which is a carbonate succession with interbedded sandstones, Pennsylvanian in age. The granitic outcrop composed of the dominant minerals quartz, potassium feldspar (some plagioclase), and biotite (field book) displayed different degrees of weathering. Different weathering features in the exposure such as grussification, jointing, and corestones suggested that grain size and biotite content were not the only influences on weathering processes taking place.
