Extended Experimental Investigation | May 28 2013 | Drosophila melanogaster lab experiment Question: How do the dominant or recessive genes in particular traits in a cross between a male and female Drosophila determine the traits of its offspring? Aim: to establish whether characteristics produced from the offspring of a drosophila cross are recessive or dominant traits. Hypothesis: If certain phenotypes are expressed in the offspring from the cross of certain Drosophila‚ then the determination

Experiment #4 (10/31/14) Lab Review Objective To introduce the basic molecules of life and to test for their presence in different substances. Introduction Macromolecules are in all forms of life. These organic compounds are carbohydrates‚ lipids‚ proteins‚ and nucleic acids. These are monomers and they link together into long chains that form polymers. Different reagents can be used to find the presence of these macromolecules. Proteins are made of carbon‚ hydrogen‚ oxygen‚ nitrogen‚ and sometimes

Brochure More information from http://www.researchandmarkets.com/reports/604386/ Analyzing Microwave Power Transmission & Solar Power Satellite Systems Description: Microwave power transmission (MPT) involves the usage of microwaves to transmit power through outer space or the atmosphere without the need for wires. It is a sub-type of the more general wireless energy transfer methods‚ and is the most interesting because microwave devices offer the highest efficiency of conversion between DC-electricity

The Effect of Metal Ions on Lichens Casey Stinnett ESC 1510 October 30‚ 2014 Introduction Lichens are a sybiotic association of fungus (mycobiont) and algae (Pediastrum boryanum . The fungus engulfs the algae‚ then supplies carbs‚ nitrogen‚ and vitamins while the algae photosynthesizes. This unusual relationship enables the lichen to grow in environments where neither fungus nor algae would normally be able to solely survive. They are found on every continent‚ ranging all the way from
