Provide and discuss examples of sequential, conditional, and iterative operations, from everyday life. How do the ways we state these operations in everyday life differ from ways we state these operations them in pseudocode? Solution 1) Sequential Operations are operations that carried out one after the other. Conditional operations are Operations that are carried out based on certain criteria. Iterative Operations are Operations that are carried out Repeatedly. Examples of them in daily Life 1) Sequential Operations are like waking up, Getting ready and going to School. 2) Conditional Operations are like if it is Weekend we do not need to go to school else if it is a weekday then we have to go to school. 3) Iterative Operations are Operations like if we like a food item we will eat until we feel it is heavy. Difference between them from Pseudo Code 1) Sequential are Operations that are carried out timely in daily life but some may not be initialized always whereas in PseudoCode we have to initialize everything. 2) Conditional also needs initialization whereas in daily life we need not initialize. 3) Iterative are Operations that where a sequential flow is followed and in daily life they can start anytime.

Mosquitoes resistant to the pesticide DDT first appeared in India in 1959, but now are found throughout the world. Graph the data in the table below. Examine the graph, hypothesize why the percentage of mosquitoes resistant to DDT rose rapidly. Suggest an explanation for the global spread of DDT resistance. Solution DDT is an effective broad spectrum insecticide. However, since it is persistant in nature and does not degrade easily, its use is banned in many countries like US. Malarial outbreaks spread by infected mosquitoes are controlled by spraying DDT in the affected areas. DDT sprays are lethal to the mosquitoes in general and immediately declines their growing populations. However, mosquitoes have a short life cycle, they are rapidly multiplying populations. Thus they can undergo beneficial mutations at a faster rate and can quickly develop resistance to the attack of insecticides such as DDT. It is always easier for a species with shorter life span to aquire genetic changes and develop resistance to the changing environment. DDT-resistant mosquitoes which may occur at very low frequency are naturally selected for survival than to DDT-sensitive populations. Thus the given graph shows an exponential increase in the population of DDT resistant mosquitoes..

Solution There are four key elements in Developing Pay Levels: For all them is needed information. Pay levels and Job structure go together, to develop pay levels is required external information, which ones are current market salaries? and to update organizational pay levels with respect the market trend to keep talented people aboard. It is a constant research effort to collecting information. In the same way, job structure is a research effort too, but it is internal, it is about to be well- informed of job descriptions and to promote internal equity, it is collecting information too..

Explain the intercellular junctions found on the lateral surface of an epithelial cell starting from the apical pole and progressing to the basal pole of the cell. How is the terminal bar seen on a light microscope related? Solution Epithelia are tissues composed of closely aggregated cells that cover most body surfaces, cavities, and tubes. Surface epithelia form continuous sheets that can have one or multiple cell layers. Several different types of cell junctions mediate physical strength and cell communication within the epithelium. A basement membrane lies beneath the epithelium and separates it from underlying tissue; because blood vessels do not penetrate the basement membrane, nutrients like oxygen and metabolites reach the epithelium by diffusion. Epithelia are polarized, with an apical surface that faces the external environment and a basal surface that faces the basement membrane. Microvilli are small processes that project from the apical surface of most types of epithelial cells, greatly increasing the surface area. They are notably found at the intestinal brush border and in the proximal convoluted tubule of the kidney. Stereocilia are unusually long, non- motile microvilli that are found on the surface epithelium in the epididymis and ductus deferens. Cilia are actively motile processes with a complex internal structure found on the epithelial lining of the respiratory tract and the female reproductive tract. The basement membrane, a thin non-cellular layer, intervenes between the epithelium and the connective tissue. This membrane is 30 to 60 nanometers thick and made up of collagenous and non-collagenous glycoproteins and proteoglycans. It provides structural support for the epithelium and serves as a selective barrier for the movement of materials to and from the supporting tissue. Using light microscopy, terminar bar appears as a bar at the apical surface of the cell, wherein the structures listed cannot be resolved. With electron microscopy, the terminal bar can be visually disseminated into these structures. The terminal bar is located on the lateral surface of epithelial cells, where the lateral surface meets the apical surface. It should not be confused with the Terminal web, which is an actinous web underlying microvilli on specialized epithelial cells.

Early mountaineers used boiling water to estimate the height of the mountains they climbed. If they reached a given peak and found that water boiled at 120 degrees F instead of 212 degrees F at sea level, approximately how high (ft) was this mountain? Show all steps. Solution At sea level, water boils at 212 °F. With each 500-feet increase in elevation, the boiling point of water is lowered by just under 1 °F. Total reduction in boiling point=212-120=92oF Let height of mountain be h h/500=92 h=92*500=46000 ft Therefore, height of mountain is approximately 46000 ft.

Discus this topic.. A nuclear reactor generates heat in the fuel rod and transfers it to the coolant. Research the design of the fuel rod and the heat transfer process. Describe the process including heat transfer coefficients. Describe differences in efficiencies between BWR and PWR processes. Solution >> A nuclear reactor produces and controls the release of energy from splitting the atoms of certain elements. In a nuclear power reactor, the energy released is used as heat to make steam to generate electricity. (In a research reactor the main purpose is to utilise the actual neutrons produced in the core. In most naval reactors, steam drives a turbine directly for propulsion.) The principles for using nuclear power to produce electricity are the same for most types of reactor. The energy released from continuous fission of the atoms of the fuel is harnessed as heat in either a gas or water, and is used to produce steam. The steam is used to drive the turbines which produce electricity (as in most fossil fuel plants). The world\'s first nuclear reactors operated naturally in a uranium deposit about two billion years ago. These were in rich uranium orebodies and moderated by percolating rainwater. The 17 known at Oklo in west Africa, each less than 100 kW thermal, together consumed about six tonnes of that uranium. It is assumed that these were not unique worldwide. Today, reactors derived from designs originally developed for propelling submarines and large naval ships generate about 85% of the world\'s nuclear electricity. The main design is the pressurised water reactor (PWR) which has water at over 300°C under pressure in its primary cooling/heat transfer circuit, and generates steam in a secondary circuit. The less numerous boiling water reactor (BWR) makes steam in the primary circuit above the reactor core, at similar temperatures and pressure. Both types use water as both coolant and moderator, to slow neutrons. Since water normally boils at 100°C, they have robust steel pressure vessels or tubes to enable the higher operating temperature. (Another type uses heavy water, with deuterium atoms, as moderator. Hence the term ‘light water’ is used to differentiate.) >> Pressurized Water Heater (PWR) A PWR has fuel assemblies of 200-300 rods each, arranged vertically in the core, and a large reactor would have about 150-250 fuel assemblies with 80-100 tonnes of uranium. Water in the reactor core reaches about 325°C, hence it must be kept under about 150 times atmospheric pressure to prevent it boiling. Pressure is maintained by steam in a pressuriser (see diagram). In the primary cooling circuit the water is also the moderator, and if any of it turned to steam the fission reaction would slow down. This negative feedback effect is one of the safety features of the type. The secondary shutdown system involves adding boron to the primary circuit. The secondary circuit is under less pressure and the water here boils in the heat exchangers which.
