Genetics of Drosophila Lab Report: The test of heredity in fruit flies In my testings with breeding the fruit flies‚ I learned that the purpose of breeding them was to test how genetics pass from generation to generation‚ also known as heredity. We attempted to breed the flies and get them as close to a 9:3:3:1 ratio as possible. This would lead to an acceptable trait ratio. My hypothesis was that if we were to breed the flies in a stable environment‚ the most common fly (or the fly with the highest

IMPULSE CONTROL DISORDERS Many of the self-control disorders involve disturbances in the ability to regulate an impulse - an urge to act. People with impulse control disorders act on certain impulses involving some potentially harmful behavior that they cannot resist. Impulsive behavior in and of itself is not necessarily harmful; in fact‚ we all act impulsively upon occasion. Usually our impulsive acts have no ill effects‚ but in some instances they may involve risk. Consider the following

green free-floating seed bearing plant. (aquaplant.com) Duckweed is known to take over the source of water it is in‚ in little time. It is forceful and can mix with other plants. The bodies of water that duckweed is mostly found in do not have waves or a strong current. They are typically only in still bodies of water although they can be found elsewhere. They are found around the globe and are the smallest flowering plant. (mobot) The population growth of duckweed is unlimited per the lab manual

CO2 Lab Report Intro Alka-Seltzer tablets are used to treat cold/flu symptoms as it produces CO2 when dissolved in water. The goal of this lab is to calculate the amount of NaHCO3 is needed to produce enough CO2 gas to fill the room. Experimental One Alka-Seltzer tablet was weighed on the analytical balance. Then a piece was measured out to be between 0.21 and 0.28 grams. 500mL of distilled water was added to a 600mL beaker. 80mL of water was mixed with 20mL of 6M HCl in a 150mL beaker. A

Lab Report Marisa McKinney P. 2 Purpose: To investigate the periodic variation of density in Group 4A elements. Background: When the elements are arranged in order of increasing atomic number‚ they exhibit periodic recurrence of properties. Elements in the same group in the periodic table tend to have similar physical and chemical properties. These similarities are due‚ in large part‚ to similarities among the electron configurations of the elements in a group. You can find periodic

Evolution Lab Report Marcos Chapa July 3‚ 2013 BIO 101 Rebecca Avants The purpose of the lab I have conducted is to analyze how altering the finch’s environment would affect the evolution of the finches by isolating each population of finches from each other‚ placing them each on a different island. This influence on the species by the environment is called allopatric speciation. One population of the finches that are located Darwin Island‚ which is 1 km‚ and the other population of finches
