EVOLUTION and NATURAL SELECTION (30 pts) a. What is a mutation? Provide 3 examples of different mutations causing specific diseases in human population. For each example explain what kind of mutation that is (ie. A point substitution‚ a chromosomal duplication etc). Mutation is a genetic mistake(s) that occur during DNA replication. 1. Progeria accelerated aging; mutation in the LMNA gene 2. Hypertrichosis excessive hair on the shoulders‚ face and ears; implicate it to a rearrangement

------------------------------------------------- Top of Form | Question 1 | Please use the following information to answer the following question(s). The collared lizard is a species found in the Desert Southwest. Male collared lizards show considerable color variation‚ ranging from brightly colored to a very dull pattern. The goal is to determine the function‚ if any‚ of male color patterns in collared lizards‚ using the scientific method. The tentative explanation is that male color

Ksenia Semina Evolution Lab ARR 3 Blast Lab Analysis: Gene 1: The 4 organisms that were looked at in the Gene 1 are bird‚ vertebrate‚ rodent and bony fish. From the Blast result the most similar gene sequence to the gene of the gene of interest is Gallus gallus collaged which is also a bird. They are the most similar because the Gallus has the highest max score out of all other genes and 100% for the ident and there is no difference in the e-value. The species is located at the bird’s branch

LAB 1 1. Describe the function of the following pieces of safety equipment and how each might be used: (10 points) a. Eye Wash (2 points) In the event of a chemical splash to the eyes‚ flood the eyes for at least 15-30 minutes with water. Flush from the eye outward. If you were not wearing proper eye wear‚ a chemical could splash into your eye and would make it necessary to use this. b. Fire Blanket (2 points) Used in order to put out a small fire. If a small area of the lab caught

2 September 2014 Chapter 1 Review 1. Describe the characteristics of science. A. The characteristics of science are observations‚ search for regularities‚ process the information‚ and self-corrections. Science is based upon observations that incorporate our senses‚ or instruments that extend our senses‚ to interpret natural experiences. Science is a searh for regularities. These regularities may include observed phenomena or patterns in nature. After observations have been recorded about regularities

Introduction: This investigation used spectroscopy to evaluate light absorption in different solutions. A spectrophotometer was used in the lab to determine these values. A spectrophotometer is an apparatus used to “measure the absorption of radiation in the visible and UV regions of the spectrum and allows precise at a particular wave length” (Jones et al.‚ 2007). The amount of light absorbed by a substance is directly in relation to the concentration of the solute and also the wavelength moving
