Please provide supporting details. 6.What are the limitations of the population dynamics lab? Is the lab activity a realistic representation of an arctic marine ecosystem? Note: Please provide detailed support for your opinion. Birth‚ death‚ migration‚ community interactions‚ and abiotic factors can influence the size of a population. Changes to

Fruit Fly Lab Introduction The major topic of this experiment was to examine two different crosses between Drosophila fruit flies and to determine how many flies of each phenotype were produced. Phenotype refers to an individual’s appearance‚ where as genotype refers to an individual’s genes. The basic law of genetics that was examined in this lab was formulated by a man often times called the "father of genetics‚" Gregor Mendel. He determined that individuals have two alternate forms

Fly Lab Shannon Ladd Introduction: Famers and herders have been selectively breeding their plans and animals to produce more useful hybrids for thousands of years. It was somewhat of a hit or miss process since the actual mechanisms governing inheritance were unknown. Knowledge of these genetic mechanisms finally came as a result of careful laboratory breeding experiments carried out over the last century and a half. A contributing geneticist named Gregor Mendel (1822-1884)‚ discovered through

Premium Gene Scientific method Hypothesis
In ecology‚ competition occurs between any organisms living in a mutual habitat. Competition can either be harmful or helpful to each organism‚ whether it is for food‚ water‚ shelter‚ etc. There are two basic types of competition: intraspecific competition or interspecific competition. Intraspecific competition is the competition that occurs between the individuals of the same species (T. Smith & R. Smith pg. 222). On the other hand‚ interspecific competition is the competition that occurs between

Pollination is service provided by insects and other small animals. Also Honey-bees distribute pollen among plants of the same species. This function of ecosystem could not be imitated by any jet invented technology. Plants

htm INTRODUCTION Ecology‚ the study of the relationship of plants and animals to their physical and biological environment. The physical environment includes light and heat or solar radiation‚ moisture‚ wind‚ oxygen‚ carbon dioxide‚ nutrients in soil‚ water‚ and atmosphere. The biological environment includes organisms of the same kind as well as other plants and animals. Because of the diverse approaches required to study organisms in their environment‚ ecology draws upon such fields as

Overview: Discovering Ecology Ecology is the scientific study of the interactions between organisms and the environment These interactions determine the distribution of organisms and their abundance Modern ecology includes observation and experimentation The Scope of Ecological Research Ecologists work at levels ranging from individual organisms to the planet Global Ecology The biosphere is the global ecosystem‚ the sum of all the planet’s ecosystems Global ecology examines the influence
Premium Ecology Ecosystem Climate
Ecology is the scientific study of interactions among organisms and their environment‚ such as the interactions organisms have with each other and with their abiotic environment. Topics of interest to ecologists include the diversity‚ distribution‚ amount (biomass)‚ number (population) of organisms‚ as well as competition between them within and among ecosystems. Ecosystems are composed of dynamically interacting parts including organisms‚ thecommunities they make up‚ and the non-living components
