The 101 mile long Conodoguinet Creek flows through about nine different municipalities‚ so testing for pollution and water quality is extremely important. To figure out the water quality of the creek however‚ we first needed to identify which tests to do. Realizing what the cause of pollution is‚ was our first problem. But‚ using prior knowledge of acid rain and eutrophication in Pennsylvania‚ we found out that those were‚ in fact‚ our main problems/causes of pollution in the Conodoguinet. When figuring

Dengue fever Dengue fever is a virus-based disease spread by mosquitoes. Dengue fever is caused by one of four different but related viruses. It is spread by the bite of mosquitoes‚ most commonly the mosquito Aedesaegypti‚ which is found in tropic and subtropic regions. This includes parts of: * Indonesian archipelago into northeastern Australia * South and Central America * Southeast Asia * Sub-Saharan Africa Dengue fever is being seen more in world travelers.

Scientific Method - Mealworms Abstract The experiment is designed to determine which substrate‚ A (oat bran) or B (peat moss) will be better nourishment for a mealworm after exposed for 7 days. A total of 30 mealworms were placed in the substrates for a period of 7 days; 15 in substrate A and 15 in substrate B. The data was compiled and analyzed on day 7 to determine the change of mass in each of the mealworms. The experiment proved my hypothesis to be correct; the mealworms would not thrive

The Effect of Temperature on Blow-fly Larvae INTRODUCTION Calliphoridae- comonly known as a blowfly‚ are living organisms which usually are the first insects to colonise a body after death. The blowfly larvae are very useful in forensic entomology. The oldest larvae give an approximate time of death of body. Family: Calliphoridae Order: Diptera Name: Calliphora vicina Aim: To check the influence of temperature of environment on living functions and activity of Blow-fly larvae.

Because they are grouped in the same kingdom‚ the nine animal phyla share the same fundamental characteristics- they are multicellular‚ heterotrophic eukaryotes that obtain nutrients through ingestion‚ they lack cell walls‚ they have nervous tissue and muscle tissue‚ and they reproduce sexually and have a unique embryonic life cycle. However‚ the animal phyla have a great number of differences as well. Some are visible to the naked eye‚ while others are less obvious‚ and still more cannot even be

1. State a possible hypothesis for Redi’s experiment. -Hypothesis for Redi’s experiment is that maggots come from larva of flies and that the meats only serve as food for the developing insects. 2. Which of the three jars in Redi’s experiment would be considered the control and why? -The jar that was left uncovered in the experiment would be considered the control because this jar represented the meat as it would normally be found with the maggots attached. 3.
