LAB QUESTIONS 1. Identify natural and human-made causes of climate change visible in the computer simulation. According to the computer model, how have sources of heat-trapping pollution changed from 1750 to today? How does the simulation predict they will change by 2050?
The sources of heat-trapping pollution, carbon dioxide, methane and nitrous oxide have grown since 1750 to today and pushed up the temperature from 57ᵒF to 59ᵒF and by 2050 the temperature rose to 63ᵒF showing an even higher increase of pollution in a shorter span of years. These three sources occur naturally and are also produced by human acts. According to the simulation’s prediction, carbon dioxide and nitrous oxide pollution in 1750 were most dominant with carbon dioxide in the lead, while methane was attributing the least amount of heat-trapping pollution. The simulation’s prediction of heat-trapping pollution in today’s world showed an increase in heat-trapping pollution build-up within the atmosphere and like before the sources were carbon dioxide (more dominant) and nitrous oxide; methane remained at a low concentration as before. By the year 2050, according to the simulation, the heat-trapping pollution increased at a higher significant rate than 1750 and today by 2050. In fact all three sources of heat-trapping pollution seemingly were at an even level in the polluted air. 2. According to the computer model and your readings, which source(s) of heat-trapping pollution contribute the most to climate change? Explain.
The sources of heat trapping pollution most dominantly contributing to climate change is carbon dioxide as proven by the computer model’s simulation. Since we humans produce an excessive amount of carbon dioxide (80%) as opposed to its naturally occurring within the atmosphere (20%), it has pushed this source to dominate heat-trapping pollution.

...effectively reduce our dependence on fossil fuels such as oil. In terms of transportation, communities need to be designed to “reduce the need for transportation” (Turk and Bensel, Ch. 6.3). Along with transportation, efforts can be made in the way we approach agriculture to also reduce our appetite for oil. Turk and Bensel (2014), point out that vulnerabilities arise from a fossil-fuel based delivery system. In order to avoid this, we must maximize local food production.

...Lab 1 – Introduction to Science Exercise 1: The Scientific Method Dissolved oxygen is oxygen that is trapped in a fluid, such as water. Since many living organism requires oxygen to survive, it is a necessary component of water systems such as streams, lakes and rivers in order to support aquatic life. The dissolved oxygen is measured in units of parts per million (ppm). Examine the data in Table 4 showing the amount of dissolved oxygen present and the number of fish observed in the body of water the sample was taken from; finally, answer the questions below. QUESTIONS 1. Make an observation – Based on the data in Table 4, discuss what patterns you observe in regards to dissolved oxygen content and fish populations in the body of water? Answer = Dissolved oxygen is crucial for fishes to live, so no fish can be observed with a 0 ppm concentration of O2 (as shown by table 4). There is a significant increase in fish population when the concentration of dissolved oxygen is 6 ppm or above. The fish population seems to be at its best at 12 ppm of concentrated dissolved oxygen. 2. Do background research – Utilizing at least one scholarly source, describe how the dissolved oxygen content in a body of water can effect fish populations. Answer = Dissolved oxygen is critical to the survival of aquatic animals. According to Tsai (1970) “When faced with low dissolved oxygen, many fish species will migrate to more tolerable regions, dramatically altering the...

...WATER QUALITY AND CONTAMINATION Name: Instructor: Institution: Course: Abstract The experiment was based on the identifying the effect of different contaminants on ground water. The yielded result indicated that, when vinegar is filtered through dirt the vinegar filtrate was relatively clean. The results noted were indicative that vinegar is not affected by contaminants that affect. Introduction In the lab report, we will have a look at how various contaminates influence the water supply. In the world, there are various contaminates that contaminate ground water. These contaminants range from the simple items we use in the house such as cooking oil and laundry detergents to the well-known contaminants that come from agricultural and industrial processes. The experiments sought to answer the question how and why these particular contaminants affect what we drink from the faucet. One of the most common contaminants in water is lead. Studies have indicated that had a detrimental effect on children especially those in the development stages of their life and cancer in adults. According to Bruce Lanphear, a renowned pediatric epidemiologist, lead found in water is usually underappreciated service in terms of intake of lead. Statistics has shown that approximately 10-20% of children are exposed to lead through intake of drinking water. Pharmaceutical chemicals are another common contaminant of water. Many individuals usually do not know that they are exposed to this......

Let’s take a look at a fast food restaurant and see. | For my chosen fast food restaurant, I chose Carl’s Jr. I made a healthy and unhealthy meal from the menu available. For the healthy meal, I chose a Charbroiled Atlantic Cod Fish sandwich, a small serving of sweet potato fries, a strawberry swirl cheesecake and a bottle of water. From the given items, I believe this was the healthiest, including all protein, carbohydrates and dietary fiber. Total Meal Nutrition * Calories – 1040 * Calories from fat – 400 * Fat – 44g * Saturated Fat – 14mg * Trans fat – 0g * Cholesterol – 90mg * Protein – 29g * Sodium – 1600mg * Carbohydrates – 131g * Dietary Fiber – 9g * Sugars – 49g While this meal has quite a bit of sodium, it has fewer calories than most other meals. This meal has a bit cholesterol and sugar, but when compared to cheeseburgers and cookies, this meal shows the healthy side. Instead of choosing a salad, I believe a cod fish sandwich was a better choice because of the protein. A full meal includes some form of protein, but with a salad, you would be missing out on the needed protein. While this meal has a lot of sodium, I believe all the nutrients balance themselves out for a rounded balanced meal. Of course fast food is going to be slightly higher with sodium, calories, and carbs,......

Yes, the groundwater sustainability will be drastically affected. “When land is cleared for human development, more flooding occurs, the transpiration rate (the amount of water evaporating into the atmosphere from the planet) is reduced and rainwater is inhibited from adequately percolating (penetrating the soil) into the ground to allow for aquifers and groundwater to be recharged. (Environmental Science, 2010) Improvements in the efficiency of water use such as improved irrigation systems as well as efficient management of modern technologies that waste more water than is needed for productions is the only solution to elude the scarcity of our freshwater supply. The six billion people that currently inhabit the population of our planet use approximately 30 percent of the total accessible renewable supply of water. It is estimated that by 2025, the percentage may increase to 70 percent, with continuous growth in population and modernizations. “Achieving sustainability and water security requires better planning, management, and technologies.

The dissolved oxygen is measured in units of parts per million (ppm). Examine the data in Table 4 showing the amount of dissolved oxygen present and the number of fish observed in the body of water the sample was taken from; finally, answer the questions below. Questions 1. What patterns do you observe based on the information in Table 4? The fewer amounts of fish, the more oxygen there is in the water. They oxygen is measured in 2’s and the less fish there is the more oxygen there is. 2. Develop a hypothesis relating to the amount of dissolved oxygen measured in the water sample and the number of fish observed in the body of water? The more fish there is, the less amount of oxygen there is in the water. According to author’s Mckinsey& Chapman, “for fishes, dissolved oxygen is an abiotic factor that can limit habitat quality and affect survival, growth, and reproduction” (Mckinsey, D. & Chapman, L. 1998, pg. 211, para. 1). 3. What would your experimental approach be to test this hypothesis? I would add fish to the water and test the oxygen, and then remove fish and test......

With Windows 10, we have the start menu, which in my case, is a reason I love Windows and its OS. Ubuntu doesn’t have one, but it is still manageable. The office applications it comes with is pre-installed and works just as fine as it would with Windows. Spreadsheets to Word, it is all in there with no hassle. The office suite that really makes the difference in both configurations is the look and feel. With icons being changed and a different feel about it. The windows landscape of it changing the closing current window bugs me because it is on the left rather than the normal right I am used to. Although Ubuntu office software is limited and only most used applications for that suite would be used on everyday uses, it doesn’t compare to that of Windows 10. The dash home environment from Ubuntu brings up limited content that you would use immediately, but not the essentials in Windows 10. I would like to implement the Start Menu to Ubuntu as many users in the Windows 8 community did not like the fact that Microsoft took the number one feature out.

...surrounding area. Typically birth rates rise faster than death rates. Honestly this can be attributed to modern science, our innate ability to adapt to changing environmental situations, and that we are typically living longer than our ancestors have. However, when pertaining to the nutria, their population increases dramatically because their birth rate sky rockets compared to their death rate. According to the video, they are extremely over populated. The nutria’s increasing population can be attributed to one amazing factor; the female can give birth to forty babies in just three years, and they can start procreation at just six months of age. So one female nutria has forty babies in three years, at the age of 3 ½… by the time she turns 4 years old, her forty babies (even the youngest) could already be on their way to making babies of their own. Maybe by that point, her earliest babies have already had 40 of their own, as they’d be about 3 ½ years old. As you can see, it adds up. As with any other living thing in the world, when the environment in which they have sustained their lives becomes depleted, there are three reactions. They will either move on to another environment which can sustain their lifestyles until that place is depleted. OR they will adapt to the situation in which they have found their selves, changing their eating and mating habits accordingly. Or, they will die out. Frankly, I don’t know enough about the species to be able to accurately......
