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 foundation water from aquifers along the coastlines nominate cause lateral and vertical intrusions of saltwater. saltwater intrusions decreases the summation of water storage in aquifers and an step-up 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- at that place be a variety of ways in which organisms are affected by saltwater intrusion. The main one being algae blooms. algae blooms occur when there are heights levels of foods available to algae in a body of water. alga blooms can trio to dissolved oxygen depletion, anoxia, and a life-size number of tilt kills in a body of water. (Richmond, 1999) Purpose-The place of this experiment is to hit the power pollution has on the environment, and the effect that saltwater has on algae growth.

Materials- * One leaven bulwark 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 plenty 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 for each one were to recieve. The first tube was the retard with no treatment added to it. The succ eeding(a) tube we added 5 mL of Alga-Gro to ! make the total heap 10 mL. The number tube would be filled with 5 mL of pond water, 4 mL of Alga-Gro, and 1 mL of the pollutant for a tautness 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 put in was finished we repeated these locomote to make a second group of...If you want to compact a full essay, dictate it on our website: OrderCustomPaper.com
