The Drosophila melanogaster In this experiment‚ the species Drosophila melanogaster‚ the common fruit fly‚ was studied to examine the processes of natural selection and genetic drift in the laboratory. The fruit fly has a sex linked gene determining eye colour. Located on the X chromosome‚ a fruit fly can exhibit the phenotype white eye (homozygous recessive)‚ or red eyed wild-type (dominant). Males of the species are XY‚ and as such only carry one eye colour determining X chromosome. Females

Evolution‚ an interesting topic all students ponder about during biology class but don’t know the true meaning nor the examples to support it. Evolution is the theory discussing the changes in heritable characteristics of a population over generations. Populations such as cows‚ birds‚ and giraffes. The giraffe population is quite thought-provoking when it comes to evolution. Which acquires many traits and behaviors today that evolved throughout generations‚ such as‚ short sleeping times‚ long necks

Question 1 Points: 10 out of 10 This level of organization is the defining level of biology. As far as we know‚ life is an emergent property that exists at this level. Below this level‚ no single entity is truly alive. population cell CELL CELL CELL molecule organism Question 2 Points: 10 out of 10 Your aquarium contains three goldfish‚ one turtle‚ some plants‚ and millions of bacteria and algae.

found in California. This job can provide answers to those who wonder why animals act or acted the way they did by studying them and observing their lives. In order to become a zoologist you would need a doctoral degree and a major in zoology/biology‚ although a bachelors degree would be the minmium requirement. Staying local would be great‚ so a University you can attend is San Diego State Univeristy. A Zoologist would need to work in a clean‚ well-lighted and equipped laboratory. Some zoologists

long time now and since I don’t have my biological mother in my life‚ she has been there for my sister and I since I met her. There are a lot of reasons why I can say that she is my hero. My freshman year my sister and I met her daughter in our Biology class. From there we became best friends and began to spend a lot of time together and going to each other’s house. Since then Elaine has became like a mother figure for the both us. There has been numerous times when my father had things to do concerning

focus at a lower power‚ it will stay in focus at a high power An object is always being magnified at 10x‚ so if you use the 40x objective‚ multiply these 2 values together to get the total magnification. (10x)(40x)=400x The 4 Unifying Theories of Biology 1. The Cell Theory: Robert Hooke observed cells. All organisms are composed of cells that have DNA. 2. The Gene Theory: DNA is made up of nucleotides that contain a sequence. The sequence can be changed by mutation or crossing over. 3. The Theory

prefix “eco” which means environment or habitat. At the other side of the board are some definition that corresponds to the meaning of each word. From its baseword‚ can you find the meaning of each word? Example: ecology-the branch of biology that deals with the relations of organism to one another and their physical surrounding. “eco” means environment and “logy” or “logos” means study. Tourism directed toward exotic often threatened national environments especially‚ to support

Therefore‚ some of them might reject it based on not knowing what it is‚ or based on a wrong understanding of it. Because of that‚ I find it my duty to make an easy to understand illustration of evolution‚ as I believe I understand it well. I’ll try to make this illustration as easy as possible‚ and in many places‚ oversimplified
