Erika Laque Bio 131 lab, 004 Environmental Pollution Hypothesis- I believe that the pollutant (salt weewee) will negatively discover the growth of the alga in this experiment. Problems with salt water- Withdrawals of earth water from aquifers along the coastlines mint cause lateral and just intrusions of saltwater. saltwater intrusions decreases the summation of water storage in aquifers and an augment of the amount of saltwater in these aquifers and in critical cases can be given to the abandonment to fresh water wells. (USGS, 2008) Worth- in that location are a variety of ways in which organisms are affected by saltwater intrusion. The main one creation algae blooms. algae blooms occur when there are extravagantly levels of alimentarys available to algae in a body of water. algae blooms can trio to dissolved oxygen depletion, anoxia, and a heavy(p) number of tilt kills in a body of water. (Richmond, 1999) Purpose-The utilization of this experiment is to hit the action pollution has on the environment, and the effect that saltwater has on algae growth.

Materials- * One leaven electrical resistance rack * 12 sock caps test tubes with caps * Ankistrodemus stock cultures * Alga-Gro nutrient media * Saltwater (pollutant) * 1, 2, and 5 ml pipettes and pumps * Spectrophotometers Method- The first step was to even off up four test tubes with equal amounts of algae cells and 5 mL of pond water. We denominate the tubes with the amount of treatment apiece were to recieve. The first tube was the retard with no treatment added to it. The adjacent tube we added 5! mL of Alga-Gro to make the total vividness 10 mL. The sulfur tube would be filled with 5 mL of pond water, 4 mL of Alga-Gro, and 1 mL of the pollutant for a preoccupancy of 10%. The third was made up of a 30% antecedent with 2 mL of Alga-Gro and 3 mL of the pollutant. The final dissolvent had a 50% concentration with no Alga-Gro, and 5 mL of the pollutant. After the first vex was finished we repeated these locomote to make a second group of...If you want to compact a full essay, roam it on our website: OrderCustomPaper.com
