Drosophila melanogaster is a fruit fly‚ about 3mm in length‚ and it is the insect that flies around spoiled fruit. A model organism has these traits: short life cycles and rapid development‚ small average size‚ big population‚ and fast reproduction (NCBI). Drosophila melanogaster meet all of the criteria for being a model organism. Also‚ fruit flies were used because they are very easy to handle and they require minimal resources to survive‚ as opposed to other organisms that might need more food

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

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

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

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

POPULATION GENETICS (FRUITFLY) NAME: Christopher N. Anah CLASS: BIOL 2108L INSTRUCTOR: DR. 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

Daphny Maldonado Bio Lab 2107 Kiah Britton W 10-12:30 Is H20 Bad for You? Abstract: In the village of Gopher Hollow there’s a cluster of Blue Baby Syndrome. There were four infants affected by this cluster. The families from the infants would collect their water from wells. We have to determine what’s the source of the high levels of nitrites in the water. The four sources that could be the point of contamination are a new subdivision‚ textile plant‚ an organic farm‚ and a mountain lake

uses a different method‚ one can work well in one environment while the other one works well in a completely different environment‚ there’s some sort of balance between them. Even though wind pollination is risky and pollinations with animals is a safer bet 3. Plants need the insects to carry the pollen to seeds. Since the neighbor sprayed insecticide because the Japanese beetles attacked their rose garden‚ there are no insects there to carry the pollen. Fruits won’t form unless the flowers
