Bio Lab Report In part II of the Organic Compounds in Foods lab‚ we to examining whether or not the starch in the saltine cracker can chemically break down in sugar with the presence of salivary amylase‚ which is an enzyme found in your mouth which assists in digestion. My group and I were instructed to obtain a saltine cracker from our teacher and chew on it for approximately 2 minutes. After concluding the chewing‚ we then grabbed a beaker and spit our slimy and chewed cracker into it. Subsequently

Lab 1‚ Exercise 1 • Based on the information in Table 2‚ what patterns do you observe? The number of fish that I observed in a body of water increases until the dissolved oxygen was at 12 ppm. After that point‚ the number of fish declines slightly. • Develop a hypothesis relating to the amount of dissolved oxygen measured in the water sample and the number of fish observed in the body of water. When the dissolved oxygen levels increase‚ the number of fish that

What is a gene? A gene is a continuous DNA segment that is transcribed into a single preRNA molecule. A zoologist and geneticist named Thomas Hunt Morgan is known for his research with fruit fly. Thomas Morgan was born on September 15‚1866 in Lexington‚ Kentucky. In 1886‚ he received his B.S. degree at the University of Kentucky. In 1910‚ Morgan saw that one male fly had a distinct difference about it. Instead of normal red eyes‚ this fly had white eyes (Allen). He wanted to test the breeding of

Biology 101 October 23‚ 2009 Lab Partner: INTRODUCTION All human beings have genomes‚ or DNA that include all of their unique genetic information. Every strand of DNA is different per individual‚ which accounts for human diversity in the world. Variable Number Tandem Repeat (VNTR) is a short sequence of DNA that is repeated at a specific chromosomal locus. The number of tandem repeated units vary between individuals; therefore‚ every human being’s unique sequence of base pairs can be used for

Lab 5 DECOMPOSITION (Nov 2‚ 2011) Introduction: Decomposition is the breakdown of organic material into its smaller molecules and elements. (This term is generally considered as a biotic process but one may find it also used to describe an abiotic process‚ e.g.‚ due to weathering.) The decomposing organisms may use the release of elements for nutrients and by breaking apart the carbon-carbon bonds in organic matter this can release energy for them. These smaller molecules and nutrient elements

Scientific Writing and Standard Components of a Lab Report INTRODUCTION Writing is a powerful tool. Effective communication is necessary to succeed in any field. As a professional‚ you must communicate with both your colleagues‚ and the community at large. Writing is the means of showing the value of your work. The specific style of writing in science is based on the unique audience of readers. In addition‚ writing allows one to organize one’s thoughts and clarify ideas‚ and it fosters abstract

Bio 104-03 Lab #3- Acids Bases‚ and Buffers 1. An acid is a substance that releases hydrogen ions as they desolve in water and ranks lower than seven on the pH scale. An example of an acidic substance is lemon juice. A base is a substance that accepts hydrogen ions and ranks higher than seven on the pH scale. An example of a base substance is hand soap. A neutral substance ranks a seven on the pH scale and has equal concentrations of H+ and OH-. An example of this is pure water. Electrolytes

JAMES BATTEY OVERVIEW: In this lab the Drosophila melanogaster fly species were used to do genetic test crosses. Students were taught how to manipulate phenotypes‚ collect data from F1 through the F4 generations‚ and analyze the results.INTRODUCTION: The basic principles of genetics are very often shared by a vast array of organisms. For that reason‚ it is usually only necessary to study the genetic
