Describe the tools and technology used to support IT project management. What are the characteristics of future tools? Solution Project management is defined as the application of a collection of tools and techniques which are used to direct the use of the resources toward the accomplishment of a unique, complex, one- time task.This task has boundries that needs to be taken care of such as the project must be completed within time limit, cost, and quality constraints. Each task requires a particular mix of these tools and techniques structured to fit the task environment and life cycle of the task. The project management techniques related to the project initiation phase include: [16].

For a given class, the studen records are stored in a file. The records are randomly accessed and updated. Assume that each student\'s record is of fixed size. Which of the three allocation schemes (contiguous, linked and table/indexed) will be the most appropriate? Solution As each file has its own index block which stores the addresses of memory occupied by the file so Table/indexed allocation scheme would be most appropriate as we can easily access any block with help of index,.

Creat Shape classes from scratch DETAILS You will create 3 shape classes (Circle, Rectangle, Triangle) that all inherit from a single abstract class called AbstractShape which implements Shape (also created by you). You are also responsible for creating the driver class \"Assignment7.java\" (program that tests your classes and described on page 3) which does the following reads input data from a file instantiates various objects of the three shapes based on the input data stores each in a LinkedList outputs this list to an output file sorts a \"copy\" of this LinkedList of objects outputs the sorted version of the list to the output file outputs the original list to the output file This driver program also needs to \"ignore errors in the input file that breach the specified input format as described in the Assianment7,java details (see page 3 1. Shape.java This is an interface that has 2 abstract methods, and passes the responsibility of implementing the compareTo method to the class that implements Shape (you may note, nomally Comparable is \"implemented\" by a class. However, an interface cannot implement because interfaces can only contain abstract methods.

Compare the following: bacterial species, bacterial strain, and bacterial type. Explain the relationship and development of strains and types to a species. Solution Bacterial species: It is a group of prokaryotic organisms which are ecologically distinct where many ecotypes of bacteria are grouped under a genous. These bacteria show a certain level of phenotypic identity, above 95% pair-wise average nucleotide identity (ANI) and over 97% 16S rRNA identity. bacterial strain: A strain is a low level taxonomically characterized micro-organism within a particular species that show genetic variance. Bacterial types: Bacteria can be classified based on cell wall type, and shape into different types. Based on cell wall type: gram positive, cells take up purple gram stain due to peptidoglycan rich cell wall egs (Streptococcus pneumoneae). Gram-negative bacteria such as vibrio cholerae which cause cholera take up pink stain due to thick peptidoglycan layer in their cell wall. Based on shape bacteria are classified into coccus (spherical shaped bacteria, egs.streptococcus), bacillus (rod-shaped bacteria egs. Ecoli), Vibrio (spiral or comma-shaped bacteria egs. Vibrio cholerae), spirillum (Spiral shape bacteria with more rigid structure egs: Heliobacter Pylori corkscrew shaped bacteria), Spirochete (Long thin flexible bacteria which are corkscrew shaped egs: Treponema pallidum) A species is a higher taxonomical classification which further breaks down into different strains that are genetically different. A type of bacteria shows which morphological differences and cell wall characteristics of a bacteria. The lowest level of classification would be based on type of species. A group of organisms of the different type, different morphological feature and virulence carrying out similar function would be classified under a strain. These strain would have micro-organisms, with genetic variance egs. A species of bacteria E. coli lives in the intestine and is good for human but it can also turn out to be pathogenic due to the 5% genetic variance among strains. Enteropathogenic and enterotoxigenic bacteria cause diarrhea in humans particularly children. Many such strains are grouped together under species egs E. Coli species. Which contains all the pathogenic and nonpathogenic E.Coli bacteria. These bacteria have 97% 16s rRNA identity, therefore falling under one species..

Acid rain negatively affects plants by A. reducing the photosynthetic rate in the leaves B. burning the leaves and bark. C. leaching cations that the plant needs from the soil D. leaching anions from the soil that the plant needs Solution Acid rain is a mixture of inorganic acids like H2SO4 and HNO3. These acids are from upon the reaction of pollutant like NOx and SO2 with water oxygen and other components present in the air. Both the acids are strong acid and it is the property of strong acid to dissociate into proton and Sulphate or Nitrate ions. In the soil cation, such as Potassium, calcium and magnesium are present, in their mineral forms, which are exchange with proton in acidic condition. Once cation is exchanged they leach into the soil are no more available for the plants..

A protein, called pRb (protein for retinoblastoma) is synthesized by a gene (Rb) on chromosome 13 in humans. When mutant or absent in the homozygous state in a retinal cell, there is a high likelihood of developing a cancerous condition of the eye called retinoblastoma. Nonmutant pRb binds with and temporarily inactivates E2F, a transcription factor that stimulates genes to produce proteins that initiate S phase of the mitotic cell cycle (thus, Rb is a negative regulator of cell division). When phosphorylated in response to a variety of normal stimuli, pRb normally releases E2F and cell division is stimulated. Thus, Rb is a tumor suppressor gene. (For a recent review, see H. Liu et al. (2004), \"Novel functions of the RB tumor suppressor.\" Current Opinions in Genetics and Development 14: 55–64. When retinoblastoma occurs in families, the disease tends to have an early onset and express bilaterally (both eyes). When sporadic (spontaneous, not inherited), it tends to show later onset and be unilateral (one eye only). Individuals who inherit a predisposition for the disease are Rb+/Rb– and may get retinoblastoma by having a mutation in the Rb+ allele.Assume that two heterozygous parents have children. One would expect the Rb–/Rb– genotypic combination in a zygote (one-cell stage of an individual) to be characterized as: a.lethal (inviable or lasting a relatively short time) b.completely normal c.having a very low likelihood of developing retinoblastoma d.having unilateral retinoblastoma only Solution A. the Rb-/Rb- genotype B. the Rb+/Rb- genotype C. the Rb+/Rb+ genotype So answer is A.

What kind of bond would form between NH_4 and Cl^- to make the salt ammonium chloride (NH_4Cl)? Iconic. Polar covalent. Hydrogen. Nonpolar covalent. A or C, depending on conditions. When two atoms are equally electronegative, they will interact to form a hydrogen bond. nonpolar covalent bond. pair of ions. ionic bond. polar covalent bond. A(n) occurs between nonpolar molecules. ionic attraction van der force hydrogen bond nonpolar covalent bond Which of the following statements about the density of water is accurate? dense than water vapor. Liquid water is denser than ice, which is more water behaves like other substances in terms of density. At all temperatures, water vapor. liquid water, which is water vapor is denser than ice, which is more dense than liquid water. Solution Answer: Answer: 6). a). Ionic NH4Cl, or Ammonium Chloride, is a salt, which means it has an ionic bond. 7). d). nonpolar covalent bond Nonpolar covalent bonds are a type of chemicalbond where two atoms share a pair of electrons with each other. Polar covalent bonding is a type of chemical bond where a pair of electrons is unequally shared between two atoms. 8). c). van der Waals force If the molecule is nonpolar, then no dipole-dipole interactions or hydrogen bonding can occur and the only possible intermolecular force is the weak van der Waals force 9). a). Liquid water is more dense than ice, which is more dense than water vapor When water freezes, water molecules form a crystalline structure maintained by hydrogen bonding. Solid water, or ice, is less dense than liquid water.Ice is less dense than water because the orientation of hydrogen bonds causes molecules to push farther apart, which lowers the density. In the gas/vapor phase, molecules have very little interaction with each other and they are at large distance, whereas in liquid and solid, molecules are in continuous contact with each other. It is therefore clear that there are more molecules per liter in ice than in water vapor, and therefore the density is larger..
