In order to begin the experiment‚ culture vials for the flies were created. After wearing the proper safety gear‚ including but not limited to gloves and a lab coat‚ the fly food source was made using roughly an equal amount of distilled water and fly food. These were mixed until it had a mashed potato-like consistency. It mustn’t be too liquid-like as it will kill the flies; and should be solid enough to not slide around the vial. After obtaining and labelling a new vial‚ the food mash was placed

Fruit Fly Genetics Lab Kelly Hernandez 5/31/14 Drosophila melanogaster is a small‚ common fly found near unripe and rotted fruit. It has been in use for over a century to study genetics. Thomas Hunt Morgan was the best biologist studying Drosophila early in the 1900’s. Morgan was the first to discover sex-linkage and genetic recombination‚ which placed the small fly in the forefront of genetic research. Scientists have used Drosophila for many reasons. For one they are very easy to maintain‚

Ecology #1 1- Define abiotic and biotic components of the environment. Natural environment includes all the living and non-living components occurring naturally on Earth. The biological components of the ecosystem that is the biotic components interact with the physical entities (abiotic components). The scientific study of the interaction of biotic community with each other and with abiotic components is known as Ecology. Abiotic Components The abiotic components are also known as the abiotic

1. Define ecology. Identify the two features of organisms studied by ecologists. Ecology is the scientific study of the interactions between organisms and the environment‚ which in turn determine both the distribution of organisms and their abundance. Ecologists study how interactions between organisms and the environment affect phenomena such as the number of species living in a particular area‚ cycling of nutrients in a habitat‚ and the growth of populations. 2. Describe the relationship between

ESSENTIALS OF ECOLOGY (Chapter 9) 1. Review the Key Questions and Concepts for this chapter on p. 184. What factors led to the premature extinction of the passenger pigeon in the United States? Factors that led to the premature extinction of the passenger pigeon are uncontrolled commercial hunting and habitat loss. Passenger pigeon in the 1858 became a big hunting business. Weapons like shotguns‚ traps and artilleries were used and even the burning of sulfur in suffocating the birds. These threats

Population ecology is the branch of ecology that studies the structure and dynamics of populations. In population ecology a population is a group of individuals of the same species inhabiting the same area. In contrast to genetics‚ where the population is a group of interbreeding individuals of the same species‚ which is isolated from other groups and in human demography‚ the population is the set of humans in a given area. Population density is a common biological measurement and is often used

Estuarine Ecology Classification of Estuaries Classification of estuaries is based on: Classification based on Geomorphology Classification based on Water Balance Classification based on Hydrographic Classification Based on Geomorphology Lagoon – oriented parallel to coast‚ with large fraction of surface area in water‚ little in marshes; usually shallow (2m depth); wind dominated water mixing; often behind a sand barrier or a coral barrier reed formed during interglacial 80‚000 years ago

The Dumpy Sepia X Wild Type Dihybrid cross using Drosophila Melanogaster. Abstract An experiment was performed on the fruit fly (Drosophila Melanogaster) in order to investigate Gregor Mendel’s postulates and determine if his laws were in fact correct. This was done by crossing Virgin Wild type females with Dumpy sepia males‚ and then inter-crossing their progeny (the first filial generation) in order to produce the second filial generation which was then studied. The results of this were designed
