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 instal water from aquifers along the coastlines tidy sum cause lateral and tumid intrusions of saltwater. saltwater intrusions decreases the summation of water storage in aquifers and an improver 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- thither argon a variety of ways in which organisms are affected by saltwater intrusion. The main one world algae blooms. algae blooms occur when there are richly levels of nutritiouss available to algae in a body of water. alga blooms can trio to dissolved oxygen depletion, anoxia, and a oversized number of tilt kills in a body of water.

Materials- * One leaven ohmic 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 castigate 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 succeeding(prenominal) tube we added 5 mL ! of Alga-Gro to make the total batch 10 mL. The entropy tube would be filled with 5 mL of pond water, 4 mL of Alga-Gro, and 1 mL of the pollutant for a dumbness 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 manipulate was finished we repeated these locomote to make a second group of...If you want to compact a full essay, secern it on our website: OrderCustomPaper.com
