AP Biology Dissolved Oxygen and Aquatic Primary Productivity Purpose: To measure and analyze the primary productivity of natural waters of laboratory cultures using screens to simulate the decrease of light with increasing depth. Background: Dissolved oxygen (DO) is how oxygen is measured. Oxygen is required in cellular respiration‚ so it is very important for aquatic life. When more oxygen is consumed than is produced‚ dissolved oxygen levels decline and some animals could die if they do not

Core issue: consumption causes global inequality. Global inequality is the inequality in distribution of income and wealth between rich and poor countries. A concentration of wealth is in the hands of very small number of people. A study by the World Institute for Development Economics Research at United Nations University reports that the richest 1% of adults alone owned 40% of global assets in the year 2000‚ and that the richest 10% of adults accounted for 85% of the world total.

Devil fish‚ also known as suckermouths‚ have invaded the waters of the Mexican state of Tabasco. This armored catfish is cherished among aquarium owners because they eat the algea that grow in the tanks‚ but out in the wild‚ this behavior harms underwater plant life and erodes shorelines. Along with this‚ the introduction of these fish has resulted in a decrease in numbers of Robalo‚ or snook‚ in these impacted waters. It’s unclear as to how these devil fish became a problem‚ but it’s thought to

Abstract This research paper examines the consumption of sugar in the average American diet‚ and argues that the average amount consumed is excessive. Sugar is detrimental to health‚ and is the root cause of obesity and a multitude of health issues. Health can be markedly improved by reducing the amount of sugar in the diet.

INNER FISH CHAPTER 1 1. The author and his colleagues wanted to use 375 million old rock‚ because in the 385 million year old rocks they found what look like fish. In the 365 million year old rocks they found amphibians that did not look like fish‚ so to find the change the look at the 375 million year old rock to find transition between the two. In their paleontology work in 2004 they found sedimentary rocks in Pennsylvania and on the east coast of Greenland‚ but their most successful rock was

Modified Winkler method for dissolved oxygen determination Abstract In this study the group has determined the presence of oxygen in sample through a modified winkler method. The amount of oxygen is determined through a series of reaction. A body of water can sustain life if dissolved oxygen is sufficed. Depletions in dissolved oxygen can cause major shifts in the kinds of aquatic organisms found in water bodies. Introduction The amount of dissolved oxygen present in water or wastewater is

deforestation of our rainforests is effecting our environment and us more than you may think. We get the oxygen we need from trees‚ forests protect us from Carbon Dioxide‚ and forests protect most of Earth’s plants and animals. We need trees to breathe and rainforests to protect us from harsh things that we emit from our bodies. Many rainforests help and protect us. “More than 20% of the world’s oxygen comes from the Amazon” (Fraser 2)‚ the Amazon is an immense rainforest located in South America. There
