New Military Base There are many types of military bases; some have piers for ships and submarines‚ others have air strips for planes and others provide training for military members. A new military installation can provide employment opportunities for community members. A military base can increase the revenue generated by local businesses‚ create job opportunities for locals and even add revenue to our local government. A military base will be a good addition to the community. A new

Chemical Separation Introduction: The objective of this experiment was to extract the pigments from spinach leaves‚ perform Thin Layer Chromatography (TLC) on the spinach leaf extract‚ and then determine the best solvent mixture to use to separate the pigments in the extract. The pigments are located inside the chloroplast walls in the cells of the spinach leaves. In order to obtain the pigments the cell walls must be broken down thus exposing the pigment containing chloroplasts. Upon

A carboxylic acid is an organic acid characterized by the presence of at least one carboxyl group. The general formula of a carboxylic acid is R-COOH‚ where R is some monovalent functional group. A carboxyl group (or carboxy) is a functional group consisting of a carbonyl (RR’C=O) and a hydroxyl (R-O-H)‚ which has the formula -C(=O)OH‚ usually written as -COOH or -CO2H. Carboxylic acids are Brønsted-Lowry acids because they are proton (H+) donors. They are the most common type of organic acid. Among

Introduction DNA (Deoxyribose Nucleic Acid) is a nucleic acid that has many names‚ each representing the phases that it undergoes (chromosomes‚ chromatin‚ genes/alleles); it resides in the nucleus (bound by 2 *phospholipid bilayers) of almost every cell in the body (red blood cells being an exception). DNA (your genotype) is double stranded and is responsible for replicating (from 46 to 92) during Interphase‚ so that mitosis can make new cells‚ repairing and allowing for growth in the body. It is

the pH value outside of the normal range‚ and what acid/base imbalance did this pH value indicate? The pH was within the normal range until the subject started to hyperventilate. The rising pH indicated that the body was expelling CO2 and H+. 7. Did the PCO2 level change during the curse of this run? If so‚ how? Yes‚ the PCO2 level dropped from 40 to 19.7 because the body was getting rid of CO2 by hyperventilating. 8. If you observed an acid/base imbalance during this run‚ how would you expect

DNA Extraction Lab Problem Statement: Do you think you have ever eaten DNA? Background Information: DNA is too small to see under a regular microscope‚ so how can it be studied? DNA is a large molecule found in all living things; therefore it is possible to extract it from cells or tissues. All we need to do is disrupt the cell’s plasma membrane and nuclear envelope‚ make the DNA clump together and - voila! - DNA extraction is possible. DNA extractions from onion‚ bananas‚ liver‚ or wheat
