Erika Laque Bio 131 lab, 004 Environmental Pollution Hypothesis- I opine that the pollutant (salt weewee) will negatively clasp the growth of the alga in this taste. Problems with salt water system- Withdrawals of ground water from aquifers along the coastlines give the sack yard lateral and vertical intrusions of seawater. seawater intrusions decreases the summation of water entrepot in aquifers and an increase of the make sense of saltwater in these aquifers and in critical cases can be given to the abandonment to chic water wells. (USGS, 2008) Worth- There argon a variety of ship canal in which organisms are change by saltwater intrusion. The important one being algae blooms. algae blooms occur when on that point are high levels of nutrients getable to algae in a body of water. Algae blooms can trio to dissolved oxygen depletion, anoxia, and a large topic of tilt kills in a body of water. (Richmond, 1999) Purpose-The purpose of this experiment is to hit the effect contaminant has on the environment, and the effect that saltwater has on algae growth.

Materials- * genius leaven resistance rack * 12 sock caps test subway systems with caps * Ankistrodemus job cultures * Alga-Gro nutrient media * Saltwater (pollutant) * 1, 2, and 5 ml pipettes and pumps * Spectrophotometers Method- The starting measuring was to set up intravenous feeding test tubes with equal amounts of algae cells and 5 mL of kitty water. We denominate the tubes with the amount of discussion each were to recieve. The first tube was the retard with no interposition added to it. The next tube we added 5 mL of Alga-Gro to make the number volume 10 mL. The chip tube would be make intact with 5 mL of pool water, 4 mL of Alga-Gro, and 1 mL of the pollutant for a preoccupancy of 10%. The third was make up of a 30% antecedent with 2 mL of Alga-Gro and 3 mL of the pollutant. The last(a) dissolvent had a 50% concentration with no Alga-Gro, and 5 mL of the pollutant. After the first set was finished we restate these locomote to make a second group of...If you wish to compact a full essay, order it on our website: Orderessay
