Chinook salmon (Oncorhynchus tshawytscha) is an ecologically and economically valuable species that is found along the Pacific coastlines of Asia and North America. Unfortunately, many Chinook populations have been steadily declining during the last century, primarily due to a variety of human activities. These threats include hydroelectric dams, chemical pollution from planes (Dietrich, et al., 2012), and sound pollution from industry (Halvorsen et al., 2012). North American governments and…

Have you ever been mowing your lawn and your lawn mower seems to be having a tough time? You've checked the gas and its all gassed up, the grass bag is empty. What could possibly be wrong with it. Well it's most likely your lawn mower is in need of an oil change. I'll be teaching you how to do that yourself so you don’t look like a dandy. You'll need a role of paper towels or an oil towel, two empty milk cartons, SF, SG, SH, or SJ oil depending on what your hardware store offers, a funnel and a…

Introduction The purpose of this lab was to determine the rate, function, and integrity of the heart during an exercise EKG. An electrocardiogram measures the electrical activity of the heart over time. In this lab a subject will exercise for about 15 minutes, not including rest times and the EKG will measure the heart’s activity. Methods Collect the following demographics for the subject: age, gender, height, MI, skinfold measurements, and weight. Locate the 10 electrode sites and shave the…

The steelhead trout used to be a native species to the Arroyo Del Valle in Pleasanton, California. Some are anadromous fish (i.e. they spend most of their time in freshwater developing after they hatch and then spend part of their later life in the sea or ocean) but others will remain in a freshwater stream or creek their entire lives. Typically, anadromous populations swim up the creek in winter to lay their eggs and then swim back, leaving the eggs to develop on their own. In order to lay…

For eras, females as well as males have tried diverse ways to get rid of undesirable hair. Fundamentally, there are two categories of methods to confiscate unsolicited hair. The first one is provisional and the other one is perpetual. Some specimens of temporary hair removal approaches are shaving, plucking, threading, waxing, sugaring and using depilatory creams. Although speedy and low-cost, its outcomes only last for a couple of days. They also necessitate more maintenance than permanent hair…

It has come to my concern and attention that recycling should be mandatory in ISA. Americans make more than 200 million tons of garbage each year due to the garbage outburst that is not recycled. I personally believe that recycling should be mandatory in ISA because the EPA system averages out that 75% of the American waste stream of garbage is only 30% recycled which isn’t even half of it. Therefore ISA should go green and have recycle bins which then the recycled items will be processed to a…

Saltwater angle aquariums come in various sizes to suit your necessities. The measure of your aquarium will decide what number of fish you can have as well as what assortments you can have since the difference in the extent of tropical fish shifts massively from an inch or two up to an astounding 18 inches. Dissimilar to freshwater angle aquariums, saltwater angle aquariums are more multifaceted to set up, require more upkeep and the aquarium itself in addition to the fish to go in it are more…

Dehydration is known as the process of removing water. During chemical dehydration covalent sigma bonds are broken into a hydroxyl group and a covalent sigma bond is broken to a hydrogen on an adjacent atom. A covalent pi bond forms between the two atoms on which the OH and H are bound and therefore chemical dehydration forms a new water molecule along with a new double bond. In this experiment 2-methycyclohexanol will react with phosphoric acid, the phosphoric acid will act as a catalyze.…

animals live. Lizard-fish, which had the highest mean LDH activity, tend to live in shallow and deep waters all around. They like to burry themselves in sand or mud on the bottom and not move until prey comes along. My group’s hypothesis was incorrect, croaker fish did not have the highest LDH activity. Lizard-fish and croaker’s have similar habitats, but lizard-fish are more commonly found in deep water which has less oxygen available. A study done on aerobic and anaerobic capacity in muscle…

My national park was Mount Rainier National Park, Mount Rainier is one of the oldest national parks in the United States, Mount Rainier itself is at about 1 million years old. Mount Rainier is also Washington’s tallest peak, and it has the 17th highest summit in the United States, its summit is about 14,410 feet; Mount Rainier National Park itself was founded in 1885. Mount Rainier is actually an active volcano, but the snow covers up the lava underpinnings. Mount Rainier also use to have life…
