The culture and economy of shellfishing Shellfishing and aquaculture have been an important part of the culture and economy of Cape Cod for many years. Shellfishing is a major contributor to Massachusetts economy, and Cape Cod’s coastal economy also relies on recreational and commercial shellfishing, as well as the tourist and seafood industries (Ensuring a Shellfish Future, Maggio, 2015). On Cape Cod, the commercial shellfish aquaculture supports 1,400 jobs, 17,000 recreational harvesters…

If you want to build muscles there a number of things you need to know. First, you have to feed your muscles to help them grow strong and fast. Proper nutrition is important. Secondly, you need to look at your work schedule. You have to understand what you do in the gym and how to do it properly. This will enable you to get results faster and avoid harming yourself. Lastly, you must know how to rest to allow muscle rejuvenation. Nutrition also has to do with supplementation. Remember that…

through the wrong entrance. They ended up on the other side of the submarine and could not find their tanks that were necessary for decompression. Chris and Chrissy decided to risk the nitrogen in their blood and descent quickly, which could be fatal, instead of drowning. As Chris made his way out of the water, the nitrogen bubbles began to overwhelm his…

The Species-Rank abundance curve for Run (Figure 1.) and Riffle (Figure 2.) treatment shows similar relationship between rank abundance and log10 abundance for dominance preemption and the observed data. Since the data in both treatments resembled the Dominance preemption model, species assemblages are unstable. The dominance preemption model supposes that the first species to invade the communities of relatively few species where a single environmental factor is of dominating importance. Only…

these base guidelines to write a well balanced equation with physical states and all of the reactants and products that are produced. Our first equation was the synthesis (composition) of magnesium reacting with oxygen and magnesium reacting with nitrogen. The magnesium began looking like a strip which was silver and smooth. Once lit it began to produce a vibrant white/yellow light that enveloped…

is almost always referred to as smog is a gas that is formed in the atmosphere when three atoms of oxygen combined. Our main concern should be with the ground-level ozone. Ground-level ozone is created by the chemical reactions between oxides of nitrogen and volatile organic compounds in the presence of sunlight. The outbursts from industrial facilities and electric utilities, motor vehicle exhaust, gasoline vapors, and chemical solvents are some of the major foundations of oxides…

keratin is hard and tough. The lsta property of keratin is it’s Ph. There are two types of Keratin, type 1 keratin is acidic and type 2 keratin is basic to neutral. The elements that are found in a keratin molecule are Carbon, Oxygen, Hydrogen, Nitrogen, and Sulfur.…

Introduction Acid rain is a rain that contains a high concentration of pollutants, chiefly sulfur dioxide and nitrogen oxide, released into the atmosphere by the burning of fossil fuels such as coal or oil .It can have harmful effects on plants, aquatic animals and infrastructure, when the sulfur dioxide and nitrogen oxide, react with the water . The chemicals in acid rain can cause paint to peel, corrosion of steel structures such as bridges, and weathering of stone buildings and statues.…

these plant species enter into a symbiotic relationship with root-nodule bacteria, referred to as Rhizobia. Based on the results, the increase in biomass under rhizobia+ fertilizer is strongly influenced by the symbiotic relationship of pea with nitrogen fixing bacteria (Franche et al., 2009). Change in biomass under Rhizobia only was also high but not higher than Rhizobia+ fertilizer, this is because the addition of fertilizer in Rhizobia +fertilizer had speed up…
