“Gretchen, come up and see the moon.” She didn’t answer, but a child’s voice startled me. “Help!” A young girl was clearly visible in our wake. I yelled louder for my wife and she hurried up the companionway, “What, Alec?” “There’s a girl in the water.” Gretchen grabbed the spotlight, “How far away?” “Three…
Introduction: Leaf Disk float in water alone. When a solution consisting of a small amount of sodium bicarbonate is added to the water it causes the leaf disk to sink. As photosynthesis continues in the leaf disk it releases oxygen and causes the leaf disk to rise. While cellular respiration is occurring also the rate that the disk raise is an in implicit measurement of the net rate of photosynthesis. The independent variable in this lab is the solution and the light because it can be…
traumatizing experiences in the wilderness. He gained intelligence, courage, and confidence during these experiences. He learned information that an average person wouldn’t know. He knows what to do in a time of trouble. He is not afraid to do the right thing. He knowns that plans are going to work out. Brian is a very intelligent person. When Brian and Derek first arrived Brian knew it was going to rain in six and a half hours just by smelling the air. He built a raft. Many people don’t know…

For example, most residents had to use the sluggish murky water of the dam except for the wealthier people which could order water from certain companies. London was unsanitary because people didn’t have baths only in the wealthiest of homes they often thought they were bad. The same goes for toilets people would basically use chamber pots and…
The Honorable Andrew M. Cuomo Governor of New York State NYS State Capitol Building Albany, NY 12224 September 30 2015 Dear Mr. Cuomo, I know that you have been bombarded time and time again about whether or not to allow hydro fracking in the Marcellus shale in the state of New York. Although a member on the board of a company with hydrofracking skills, I am split with the idea of hydro fracking. Both sides’ present solidifying arguments and I clearly understand the advantages and…
ammonia with acids or known as ammonium salts and contain the ammonium ion, NH4+. NH3 also ionizes to a small extent with metal oxides and the halogens. Like water, ammonia undergoes molecular autoionisation to form its acid and base components, decomposing to NH4+ and NH2- (“CHEM-GUIDE”). Ammonia is combustible in air, producing nitrogen gas and water. The combustion of ammonia is exothermic and usually needs some sort of catalyst to occur. While ammonia is highly stable, it can be decomposed…
Ecological succession is the process in which ecosystems develop and change over time. The habitats are constantly changing, and will never stay the same. There are two main types of succession, primary and secondary. Primary succession is one of the two types of biological and ecological succession. It is the establishment and development of an ecosystem that was lacking any inhabitants beforehand. Example would include melting glaciers, volcanic eruptions, or landslides. Secondary…
It is essential for pharmacists to be able to predict the theoretical rate kinetics of pharmaceutical products in order to determine its shelf life. As the shelf life is defined by (t90), which is the availability of greater or equal to 90% of the drug, it is important to discover the rate of degradation of a drug to ensure that the patients receive an adequate dose of the drug. In this experiment, the stability of the active ingredient of Aspro Clear is investigated to identify the rate of…
influencing the failure of completing the trick because the fish would not interact with the incentive that was presented. In order to persuade the goldfish to complete the task, the food was going to be constantly raised higher until it located out of the water, in which the fish would have to jump and reach it. With the fish showing a great level of uninterest in the food, it resulted in the failure to teach the fish to jump since there was nothing to engage the animal with.…
