flukes are grey and spotted with white C. Habitat: (Zone) Benthic and coastal (Geographic): From Alaska to the Caribbean D. Specific Characteristics: 1) Reproduction: Polygamous; Seasonal breeding 2) Feeding Techniques: Filter feeders; Bubble netting‚ Ring of foam‚ Lunging. 3) Defense Techniques: Humpbacks have few predators other than humans‚ and don’t have any defensive techniques. Some of the largest animals on Earth are the gentlest. The humpback whale is a stellar

Full Moon Phenomenon A black cat crosses the road and it is bad luck‚ you aren’t supposed to open an umbrella inside of the house or a building‚ or break a mirror. These are all superstitions are that people believe in‚ it starts as early as age eighteen months when children start to exhibit a form of magical thinking when they begin to create imaginary worlds while playing. One superstition I grew up thinking was true and until recently I still did was that crazy things happen when a full

Mud weight otherwise known as drilling fluid density is a very important property of the drilling fluid which must be determined regularly during the drilling process. It is defined as the weight per unit volume of the drilling fluid or drilling mud usually expressed in units of g/cm3 or more conveniently lb/gal. Drilling fluid density or mud weight must be measured at regular intervals of the drilling process because as different formations are encountered during the drilling process‚ different

concentration of the enzyme. Hypothesis: The assay system used in the lab consists of a filter paper disc coated with the enzyme and the dropped into a papercup of substrate (Hydrogen Peroxide). As the hydrogen breaks down the hydrogen peroxide into hydrogen and oxygen gas‚ the bubbles of oxygen gas collect underneath the filter and make it rise to the surface of the hydrogen peroxide. The time it takes for the filter to rise is an indication of the rate of the rate of enzyme activity. Rate of enzyme

wait for beaker 2 to cool and then we had to be weigh it on the electronic pan balance. After weighing beaker 2 we had to shift our focus to the filter paper residue from beaker 1 and we place it onto a dry evaporator dish. Then we had to fill a graduated cylinder with 10 mL of 3.0 M HCL and it had to be poured slowly into the evaporator dish. Once the bubbles had stopped forming we had to decant the liquid into beaker 1 and then we used 5 mL of distilled water to rinse the rest of the sand out of the

mixture caused an immiscible appearance of the solution in the separatory funnel. By briskly shaking the separatory funnel with the mixed components created a build up of pressure which was released through the stopcock forming small disappearing bubbles within the tip of the separatory funnel. Once the funnel was placed back into the iron ring and the stopper was removed‚ the distinct upper ether layer had an oily appearance and a visible barrier separating it from the lower water-organic base or
