invertebrates that alert us to pollution problems in an environment. Indicator species are used to assess pollution because they change rapidly in response to changes in ecological variables‚ such as food availability‚ water temperature‚ amount of dissolved oxygen in the water‚ pH levels‚ and other factors. Suppose you are an ecologist studying the effects of acid precipitation on plant life. Describe an experiment you would perform in order to determine which plant species would be a useful indicator

1257/jel.49.2.326 What Determines Productivity? C S * Economists have shown that large and persistent differences in productivity levels across businesses are ubiquitous. This nding has shaped research agendas in a number of elds‚ including (but not limited to) macroeconomics‚ industrial organization‚ labor‚ and trade. This paper surveys and evaluates recent empirical work addressing the question of why businesses differ in their measured productivity levels. The causes are manifold‚ and

Meghann Kiphart AP Biology Lab Report Number One Mrs. Irvine Introduction: Because all molecules have kinetic energy and are constantly in motion cells go through a process called diffusion. Diffusion is the movement if molecules from an area of higher concentration to and area of lower concentration. This process with continue to occur until an equilibrium is reached. Osmosis is a different and unique kind of diffusion. Osmosis is the diffusion of

a beneficial therapy for children with Cerebral Palsy? Background: Hyperbaric Oxygen Therapy (HBOT) is being promoted as a new therapy for children afflicted with cerebral palsy. It is being utilized by several specialized medical centers in the US‚ Europe and Canada. The rationale behind this therapy is inhalation of pressurized pure oxygen within a hyperbaric chamber‚ results in higher levels of dissolved oxygen within the blood (Liptak‚ 2005). Over 15 studies have been conducted to determine

Abstract: The topic of this research involved the occurrence of genetic transformation in bacteria (E. Coli). More specifically‚ a previously prepared pGLO plasmid--which consisted of the gene to be cloned--was used to transform non-pathogenic bacteria. The pGLO plasmid contained a gene for the Green Fluorescent Protein (GFP) from a bioluminescent jellyfish and a gene for resistance to ampicillin‚ an antibiotic. Essentially‚ we wanted to determine the conditions of the bacteria that would glow.

Chapter 15 The chromosomal basis of inheritance Key ideas: 1) Mendelian Inheritance has its physical basis in the behavior of chromosomes during sexual life-cycle. 2) Morgan traced a gene to a specific chromosome. 3) Linked genes tend to be inherited together because they are located on the same gene. 4) Independent assortment of chromosomes and crossing over produce genetic recombinants. 5) Geneticists use recombination data to map a chromosome’s genetic locus. 1900 Biology finally
