iLab week 1 Assignment Lab Report: I. Seperation of a Salt Water Solution Lab II. Introduction In this lab scenario, we were asked to determine the percentage of salt present in a saltwater solution. We are able to reach a conclusion in the lab due to certain chemical properties of water and salt. One main property is that water has a significantly lower boiling point in comparison to the salt in the mixture. III. Procedure First we obtained a 250ml beaker as well as an electronic scale in grams (g) and a Bunsen burner. After weighing the empty glass, we applied the saltwater solution and weighed the beaker again. Then we evaporated the water by placing the beaker on the Bunsen burner. Then we were able to determine the amount of salt present by weighing the beaker contents. IV. Observations and Results Contents | Mass | . Beaker (control) | 75.000g | .Beaker + mixture | 85.175g | .Beaker + salt | 75.175g | . Salt | 0.175g | .water | 10.000g | Percentage of Salt in Mixture | %1.75 | V. Discussion

This, in my opinion, is a good Lab to start with. The results seem logical and the lab does a good job of demonstrating the proper application of the scientific method as well as the properties of saltwater mixtures. It also showed good basic practices to use during experimentation like the use of a control group , and measuring and recording data throughout the process VI. Conclusion The experiment resulted in the conclusion that the percentage of salt present in the mixture was…...

Provide a brief explanation with each example. Refer to Ch. 1 in the text for explanations of these dimensions. Physical health: Exercise at least five days a week. Physical fitness has to be up to par to stay in the military. I usually watch my diet because I am not as young as I use to be. Social health: Right now I really do not have a social life. It might not be healthy but I guess I do it to protect myself. Having to move around a lot does not allow me to build the friendships that I am looking for. Intellectual health: Being in the military sometimes requires critical thinking to complete a mission. Many times it’s accomplishing a mission that you have already done. I usually refer back to those past missions and put together the pieces that I need to accomplish the new one. I take to account failures and successes of my past missions and use it for the current one. I also take in to account other people’s failures and successes. Environmental health: I try to surround myself with people I can learn from.

...Solving Proportions MAT222 Week 1 Assignment September 22, 2014 Solving Proportions Solving for a proportion can be used within numerous real-world problems, such as finding the population of an area. Conservationists are able to predict the population of bear’s in their area by comparing information collected from two experiments. In this problem, 50 bears in Keweenaw Peninsula were tagged and released so conservationists could estimate the bear population. One year later, the conservationist took random samples of 100 bears from the same area, proportions are able to be used in order to determine Keweenaw Peninsula’s bear population. “To estimate the size of the bear population on the Keweenaw Peninsula, conservationists captured, tagged, and released 50 bears. One year later, a random sample of 100 bears included only 2 tagged bears. What is the conservationist’s estimate of the size of the bear population (Dugolpolski, 2012)?” In order to figure the estimated population, some variables need to first be defined and explain the rules for solving proportions. The ratio of originally tagged bears to the entire population is (50/x). The ratio of recaptured tagged bears to the sample size is (2/100). 50x=2100 is how the proportion is set up and is now ready to be solved. Cross multiplication is necessary for this problem. The extremes are (100) and (50). The means are (x) and (2). 100(50)=2x New equation, and now solve for (x). 50002=2x2 Divide......

...Week 1 Assignment 1 Michael Conley ITT Technical Institute Abstract This paper will be identifying, analyzing, and explaining five likely threat/vulnerabilities for the scenario given. I will go into detail on what you should do to lower the risk or vulnerability. The last thing I will talk about in this paper is what you should do to try and make it better and more secure. There are definitely some potential risks and vulnerabilities with the given scenario. The first one to point out would be that they are using Windows Vista. Another issue is the VPN connection with the laptops. Issue number three would be the servers. The fourth problem I foresee is back up. The final problem I see in the network is with the ISP. This is not a very old and outdated OS, since Microsoft is still supporting it, but there are more vulnerabilities with using Vista as opposed to Windows 7. Windows 7 is also more versatile, it is able to be run on more than just desktops unlike Vista. Windows 7 is able to be used on laptops, desktops, and netbooks which Vista cannot be used on all of those. Windows 7 puts all of the security notifications and other system problems in one place unlike Vista where you have to search through the control panel to find things. Windows 7 you just go to the action center. The likelihood of there being a serious security issue with windows Vista is low for right now.......

Beh225 Week 1 Assignment

...BEH/225 Week 1 Assignment 3/13/15 BEH/225 Week 1 Assignment Psychology has been around ever since someone wondered why someone else did something, so basically a very, very long time. Psychology as its own science, however, has only existed for about two centuries. Wilhelm Wundt is credited as being the first psychologist and is known as the “father of psychology” (Coon, 2013). This was done when he set up his own lab where he could monitor people’s reactions to different stimuli (Coon, 2013). He insisted on using a strict routine for observing and noting these reactions (Coon, 2013). His doing so is what began to separate psychology as its own science. There are many perspectives in psychology that can explain human behavior. On some levels there is a Pavlovian response to certain things, we learned not to touch things that are hot because we will be burned or that we shouldn’t stick out tongues to something metal in the winter time. This is a conditioned response to a stimulus which is a perspective first adopted by Ivan Pavlov, who was a physiologist, but it can help explain some behaviors (Coon, 2013) Sigmund Freud suggested that our unconscious mind determines our actions and behaviors (Coon, 2103). These are but two of the many perspectives that can help to explain human behavior. On the subject of nature (genetic potential) vs. nurture (environmental influences) vs, personal choice, I feel that I sit at the center divergence point of all three. I feel......

...iLab week 1 Essay SCI 228 Nutrition, Health, and Wellness iLab Week 1 Essay There are 14 parts of the digestive system. They include the salivary glands, tongue, pharynx, esophagus, stomach, liver, pancreas, gall bladder, small intestine, large intestine, appendix, rectum, and the anus. Food we eat first enters our mouth, which is where you find the tongue. We know it’s in there because it tastes the food we put in our mouth. You will find the salivary glands in 2 spots, under your tongue and behind your tongue. The best way to remember that it’s located there is to known that it releases saliva and there is always saliva on your tongue. Our pharynx is found in the back of the mouth. To remember it is located there I use the first half of the word which sounds like far, and then use that as a saying. The Pharynx is the start of a far travel. This is down the esophagus. The esophagus starts at the back of your mouth and runs down into your stomach. I remember it’s located there because I feel food go down my esophagus when I touch my neck. Our stomach is located underneath our heart. Most people love food. I use that to remember where our food goes after we swallow, under the heart into the stomach. The pancreas is located behind the stomach. It’s located behind the stomach because it needs to use the blood streams coming out of the heart to add enzymes it made. After the stomach, food will go into the small intestine. The best way to remember that the small intestine...
