The results of the experimental measurements will indicate the most favorable generator architecture from the point of view of the increase of concentration of oxygen dissolved in water.

of the catalase which the disk is soaked in‚ it will have a direct correlation on the rate of hydrogen peroxide being broken down into oxygen gas. Prediction: Since the rate of reaction can be lowered by the addition of catalysis such as an enzyme. Moreover to increase the effectiveness of an enzyme one must add additional amount of enzyme due to saturation. Therefore the 100% will have the greatest effect because is has the highest concentration of the catalase.

In the article‚ “Oceans Are Losing Oxygen—and Becoming More Hostile to Life” by Craig Welch‚ climate change is affecting the lives of all kinds of sea creatures. This article explains how climate change‚ and the warming of ocean water‚ has began taking oxygen out of the water. This means that many fish species have shrunk because of this loss of oxygen. The warmer water speeds up the metabolism of these fish‚ which makes them breathe in more of the oxygen. A couple of scientists from the University

To ensure the delivery of the prescribed oxygen to a patient receiving 3 liters per nasal cannula‚ the nurse should frequently monitor the patient’s: a. ABG b. Respiratory rate c. Oxygen flow-meter setting d. Nasal cannula 3. Which of the following actions by the nurse shows the most effective planning regarding the minimizing of the patient’s risk for infection

The tires absorb moisture from roads while in motion. It can also pull carbon dioxide out of the air to fuel the moss’ photosynthesis which has clean oxygen as its byproduct. Absorbing 4‚000 tons of C02 a year Goodyear’s estimate is that the Oxygene‚ if all the 2.5 million vehicles in Paris switch to the brand‚ could produce 3‚000 tons of oxygen and absorb more than 4‚000 tons of carbon dioxide annually. The tire‚ however‚ goes beyond cleaning the air.

In aquatic environments‚ enhanced growth of choking aquatic vegetation or algal blooms disrupt normal functioning of the ecosystem‚ causing problems such as a lack of oxygen in the water‚ needed for fish and other aquatic life to survive.

process of photosynthesis to begin and so the disks would not start floating unless they were placed under the sun‚ or in this instance the white light. 6. In this investigation‚ you measured the rate of oxygen production. How might you measure the rate of loss of carbon dioxide? The rate of oxygen production was measured by the amount of dicks that stated to float at a certain time. After the disks have all floated to the top‚ the rate of carbon dioxide loss could be measured by how long it takes

Scenario #1: In the hospital setting‚ if we have a patient who is in respiratory distress with rising carbon dioxide(CO2) levels and decreasing oxygen levels (measured by oxygen saturation and PO2)‚ we often decide that the best way to help this patient is to set him up on a BiPAP machine. In many instances‚ this is often used to prevent a patient from getting bad enough that he needs to go on life support. And

Introduction The aim of this practical 1 is to determine the rate of photosynthesis by measuring the rate of oxygen production‚ which is a direct consequence of PSII activity. Results Graph 1 Graph 2 Discussion i. It took 2 minutes before any increase in the O2 concentration of the chamber was observed‚ it took 2minutes‚ after illuminating the leaf. ii. There are 2 main parts of the photosynthesis‚ light dependent part and light independent part‚ the O2 is released in last part which is light-independent
