Why did eagle populations decline in the 1960\"s? Why do eagles congregate at the Shepaug River and Hudson Rivers in winter? When do they reproduce? What are their nests like? How many young do they have and when do they hatch out? What types of behavior do adult eagles engage in in winter? What percent of the time do they spend searching for food? What habitat do they prefer for nesting sites? Why? Solution Answer: 1. Why did eagle populations decline in 1960s: Different reasons contributed to a steep decline in Eagle population in 1960s: - More than 100,000 bald eagles were killed in Alaska from 1917 to 1953 as Alaskan Salmon fisherman feared that Eagles were a threat to the Salmon population - In the 1950’s the insecticide DDT (dichlorodiphenyltrichloroethane) was introduced and used widely to combat a broad spectrum of insect pests. DDT was indiscriminately used and it caused serious environmental effects DDT interferes with the calcium processing of birds and results in deformed eggshells. The chemical by products of DDT persisted in the aquatic ecosystem long after its application. Since bald eagles are at the top of the aquatic food chain and feed primarily on fish, they received concentrated doses of the chemical. When the female eagle laid a thin, deformed eggshell, she crushed it under her own weight when incubating the egg. Since bald eagles pairs breed only once per year, with many bald eagle pairs not reproducing successfully, the bald eagle population declined steeply throughout the 1960’s and 1970’s. 2.Why do eagles congregrate at the Shepaug River and Hudson river in the winters. The same elements that support breeding pairs - clean air and water, ample food supply, large undisturbed stands of trees - also attract bald eagles looking for a winter home. The Hudson River region still provides tracts of relatively undisturbed land for roosting, perching and nesting.These habitats are especially attractive during winter, when human activity is limited. Each year, bald eagles migrate from their northern nesting areas to New York\'s rivers and reservoirs in search of open water, food and roosting sites. Even during the coldest months, open water can be found near power plants that discharge water during energy production, or where the natural flows of tributaries enter the river. In recent winters, more than 100 wintering eagles have been counted along the lower Hudson.In recent years, the stretch of the Hudson from Kingston to Croton has been increasingly popular with bald eagles, probably because sections of the river are kept open by discharges from power plants, and railroad tracks provide an ample supply of dead animals (carrion) for scavenging eagles. 3. When do they reproduce? What are their nests like? How many young do they have and when do they hatch out? An eagle is sexually mature and ready to breed at about 4 to 5 years of age. For bald eagles, the complete white head and tail are signs of sexual maturity. Golden eagles.

Which of the following is an example of an intensive property? Mass Pressure Volume Total energy Solution An extensive property is a property that changes when the size of the sample changes. Examples are mass, volume, length, and total charge. An intensive property doesn\'t change when you take away some of the sample. Examples are temperature, color, hardness, melting point, boiling point, pressure, molecular weight, and density. Because intensive properties are sometimes characteristic of a particular material, they can be helpful as clues in identifying unknown substances..

What does it mean for something to be a \"dynamical system? What is a \"dynamical equation? What does it mean if a system is \" sensitive to initial conditions\"? Give one example of a dynamical system that has been shown to be sensitive to initial conditions. Solution Dynamical systems theory is an area of mathematics used to describe the behavior of complex dynamical systems, usually by employing differential equations or difference equations. Dynamical systems are mathematical objects used to model physical phenomena whose state (or instantaneous description) changes over time. These models are used in financial and economic forecasting, environmental modeling, medical diagnosis, industrial equipment diagnosis, and a host of other applications. So a simple, if slightly imprecise, way of describing chaos is \"chaotic systems are distinguished by sensitive dependence on initial conditions and by having evolution through phase space that appears to be quite random.\" In particular, a chaotic dynamical system is generally characterized by 1. Having a dense collection of points with periodic orbits, 2. Being sensitive to the initial condition of the system (so that initially nearby points can evolve quickly into very different states), a property sometimes known as the butterfly effect, and 3. Being topologically transitive.

What is the shell called that interacts to form chemical bonds? What is the \"octet rule\"? T/F: Ionic bonds are stronger than covalent bonds, because they don\'t dissociate easily. Which group has stronger electro negativity\'s: Carbon & Hydrogen, or, Oxygen & Nitrogen T/F: A condensation reaction is the addition of water, causing two monomers, for example, to combine and become a larger polymer. Solution Ans. 1 Valence shell The outermost shell of an atom is called valence shell. The electrons in outermost shell participates in formation of chemical bond. Ans. 2 Octet rule: “An atom gains or loses electron to attain the nearest inert gas configuration.” Ans. 3. False. Explanation 1: Not all Ionic bonds are stronger than every covalent bond. Some ionic bond are weaker than specific covalent bond and vice-versa. Explanation 2: Ionic bonds are stronger because of greater columbic attraction between oppositely charged ions. Ans. 4. Oxygen & Nitrogen has stronger electronegativity as they tend to attract electrons to complete their octet with greater force than those Carbon & hydrogen. Ans. 5. False. Condensation reaction is the removal of water. For example, when two amino acids join by peptide bond, there is loss of one water molecule. As a result, the mass of product is LESSER than sum of the reactants..

The origins of multiple sclerosis are not clear. What do scientists hypothesize to be the causes of multiple sclerosis. The origins of multiple sclerosis are not clear. What do scientists hypothesize to be the causes of multiple sclerosis. Solution Multiple sclerosis is an autoimmune & neurodegenerative disease in which, the myelin sheath covering the neurons present in the central nervous system is degraded. As a result, there will be decreased impulse conduction or loss of impulse conduction in that area. Depend upon the affected area, the corresponding organs may suffer from paralysis because loss of neurons communication specific regions. However, a majority of pathophysiological pathways has been illustrated but various neuroscientists to examine theses demyelinating effects but they profoundly failed to provide exact pathophysiology of multiple sclerosis Multiple sclerosis is the demyelinating disorder in which “myelin of neurons” broken due to the various factors in the both neonatal and child brain leading severe cognitive and sensory –motor impairment due to the improper functioning of the flexion reflex. Potential medication and associated treatment is very difficult as the specific drug molecules, which can act against this gene coding proteins for the synthesis of myelin. During multiple sclerosis, merely central nervous system with oligodendrocytes will be affected thereby improper myelination around the CNS neurons. Schwann cells will not get affected because these are myelin-producing cells in peripheral nervous system..

Please answer the following: Describe the two functions of loading dye. (4 points) Where would the larger fragments, those with the greater number of base pairs, be located; toward the top of the gel or the bottom? Why? (2 points) What color is the positive pole on an electrophoresis chamber? (1 point) Suppose you have 4 fragments of 500bp each. How many bands would appear on the gel? (1 points) What is the purpose of using a marker or a ladder? What is the difference between the two? (4 points) Solution Describe the two functions of loading dye. (4 points) Loading buffer increases the density of the sample hence allows the DNA sample to sink into the wells of the gel Loading buffer gives color to the DNA sample therefore allows us to visually track the DNA sample as it runs through the gel. Where would the larger fragments, those with the greater number of base pairs, be located; toward the top of the gel or the bottom? Why? (2 points) Larger fragments are heavy hence they have low mobility. They will be seen towards the top of the gel. What color is the positive pole on an electrophoresis chamber? (1 point) Positive pole is colored red and the negative pole black Suppose you have 4 fragments of 500bp each. How many bands would appear on the gel? (1 points) We would see just a single band. Since all the four fragments are of equal size, they run together in gel What is the purpose of using a marker or a ladder? What is the difference between the two? (4 points) DNA ladders are used in gel electrophoresis to determine the size and quantity of DNA fragments. marker or a ladder-These two terms mean essentially the same thing..
