    Part 2: I used a graduated cylinder on the tarred scale empty and then with both water and isopropyl alcohol to determine the mass of both and calculated their densities. Next, I measured the length, width, and height of a magnet to determine volume. I then used the water displacement method by filling a cylinder with water and then placing the magnet in and recording the difference in the water level to determine volume and density. Lastly, I used Archimedes’ method to by recording the mass of a metal bolt then placing it in water and observing the displacement. I then converted this to density of water and repeated with a magnet.…

    1. The Respiratory exchange ratio is the ratio of the volume of carbon dioxide produced and oxygen consumed. The ratio indicates the energy that the subject is expending for indirect calorimetry, how efficient the subject 's body is at utilizing the oxygen inhaled, as well as the main substrate being used for energy during varying intensities of exercise. During rest the volume of carbon dioxide was 0.73L/min, the volume of oxygen was 0.84L/min. The RQ or RER was 0.87. Based on Table 5.1(Kenney,Wilmore, &Costill, 2012; Physiology of Sport and Exercise(5th ed.) The ratio indicates that roughly 68% of the kcal that the subject was using came from carbohydrates and the remaining 32% of the kcal came from fat. During the 50W stage the volume of carbon dioxide was 2.2L/min and the volume of oxygen was 2.9L/min. The RQ was 0.79, which indicates that the 33% of the kcal that the subject was using came from carbohydrates and that 67% of the kcal came from fat. In the 100W stage the volume of carbon dioxide was 4.08L/min and the volume of oxygen consumed was 4.1L/min. The RQ came out o be 0.99, the substrate being used was only carbohydrates at this point. The 200w stage had a carbon dioxide volume of 7.91L/min and a oxygen consumed volume of 6.51L/min. The RQ was 1.2 which indicates that the body is producing more carbon dioxide than the oxygen being consumed. The substrate being used for energy again is only carbohydrates.…

    Lichens are a sybiotic association of fungus (mycobiont) and algae (Pediastrum boryanum . The fungus engulfs the algae, then supplies carbs, nitrogen, and vitamins while the algae photosynthesizes. This unusual relationship enables the lichen to grow in environments where neither fungus nor algae would normally be able to solely survive. They are found on every continent, ranging all the way from the freezing Arctic to the sweltering grasslands of Africa. Even though they can live in such extreme conditions, they do require clean air. This is why they are excellent environmental indicator. An indicator species is an organism whose presence or absence reflects the overall health of an environment. Lichens flourish where there is good air quality; however, they cannot survive where the air is polluted and toxins loom. This is because they have no stomata, or pores, to shut to keep the toxins out; therefore, absorbing all of the pollutants in the air. Because they are such unique organisms, they accumulate different metal anions in the air than other organisms, like plants do, for example. Lichens attract toxic metal ions. An ion is a charged atom. If the ion has a positive charge, it is a cation. An ion with a negative charge is an anion. During the ion exchange process, Hydrogen, an anion, is released and metal cations move in. This process occurs when lichens are exposed to polluted air. When the lichens are dropped into any of the metal solutions, their cell wall releases the methylene blue ions, which are replaced by metal cations. Upon their detachment, the ions integrate into the solution, which in turn, colors it blue. The darker the solution, the more metal cations taken in by the lichen. Valence is a measure of how much an atom wants to combine with something else. If the valence of a metal ion affects lichen uptake, then the higher the cation, the…

    In the article “How Boys Become Men”, written by John Katz, he analyzes situations he experienced while growing up. Katz believes that boys become men by not showing fear or feelings and not ratting on others. As in the novel, The Other Wes Moore, both Weses are forced to become men at an early age. They experience events that push them to make decisions that make them grow and think like men do. Katz details the maturation process for boys, as the book, The Other Wes Moore, does with both Weses. They make decisions and take actions to mature and become a men.…

    The reason for performing this experiment was to test the agnostic behavior coming from the male Betta fish. This experiment was conducting by taking a male Siamese fighting fish and placing its fish bowl next to a mirror so it would be able to see his reflection. We also exposed the fish to many others to see if the behavior was the same or different when placed next to: a goldfish, a female Betta fish, and a zebra fish. My hypothesis was supposed by this experiment and it was observed that the Betta fish was disturbed by his reflection in the mirror but his aggressive behavior decreased rapidly when other tanks, containing different types of fish, were placed next to his.…

    The purpose of this current study was to examine how individuals detected or noticed change when viewing images on their level of attentiveness. The experiment consisted of 22 participants who had to detect change across conditions for 20 minutes. These conditions were importance of change (marginal and central) and change type (color, location and disappearance and reappearance of images). These changes were presented in random order with two practice trials followed by 46 trials. The participants were exposed to all of the conditions making this experiment a within-subjects experiment. It was hypothesized that individuals would take a longer time to detected marginal changes than central change. Participants had to look at two pictures presented simultaneously and decide what changes were presented. When changes were detected the participants had to identified if the changes were color, location, or disappearance or reappearance of images within a certain time frame. It was predicted that change detection for marginal change would take a longer time to be noticed. The average mean reaction time for marginal change was longer than central change. In conclusion central change is easier to notice than marginal change.…
