State the cell theory and describe the experiments that support it State the cell theory and describe the experiments that support it Solution The three basic principles of cell theory are, Robert Hooke was first used the word “cell” to describe the (In Latin, Cellula = small compartment) structure of dead cork when he observed under microscope. His observations were published in the book “Micrographia” in 1665 by the Royal Society. When Hooke observed the cork cells, they appeared empty, resembling “Honey-comb” or small Boxes or Bladders of Air.” Because the cork cells are non-living cells. They mainly composed of a waxy material called “suberin” that restrict the passage of air and water. Rudolf Virchow was also contributed to cell theory..

How has television influenced the political process, specifically the political campaigning Solution No aspect of the political process has been affected more by television than political campaigns and elections. The first presidential election to see extensive use of television was the 1952 race between Dwight D. Eisenhower and Adlai Stevenson. In that campaign, Richard M. Nixon, as Eisenhower\'s vice-presidential candidate, \"took his case to the people\" to defend himself on television against corruption charges in the famous \"Checkers\" speech. However, the most significant innovation related to the role of television in the 1952 campaign was undoubtedly Eisenhower\'s use of short spot commercials to enhance his television image. The Eisenhower campaign utilized the talent of successful product advertising executive Rosser Reeves to devise a series of short spots that appeared, just like product ads, during commercial breaks in standard television programming slots. Not only did this strategy break new ground for political campaigning, but many observers have credited the spots with helping Eisenhower to craft a friendly, charming persona that contributed to his eventual electoral success. Stevenson made it easier for the Eisenhower campaign by refusing to participate in this type of electronic campaigning. Although Stevenson did produce television commercials for the 1956 campaign, he was never able to overcome Eisenhower\'s popularity. This early use of television for political advertising was the beginning of a trend that has grown so dramatically that televised political advertising is now the major form of communication between candidates and voters in the American electoral system. Every presidential campaign since 1952 has relied heavily on political television spots. In the 1992 election, Bill Clinton, George Bush, Ross Perot, and the national parties spent over $120 million dollars for production and airing of television spots. Even below the presidential level, spots now dominate most major statewide (particularly gubernatorial and U. S. Senate) and Congressional races in the United States, accounting for 50-75% of campaign budgets. Several reasons account for the preeminence of television advertising in politics. First, television spots and their content are under the direct control of the candidate and his/her campaign. Second, the spots can reach a much wider audience than other standard forms of electoral communication. Third, the spots, because they occur in the middle of other programming fare, have been shown to overcome partisan selectivity (e.g., the spots are generally seen by all voters, not just those whose political party is the same as that of the candidate). Finally, research has shown that voters actually learn more (particularly about issues) from political spots than they do from television news or television debates. The use of television advertising in political campaigns has often been criticized for \"lowe.

HISTORY: Why is it called \"American revolution\"? Solution The revolt has got his name as American revolution because of two major changes 1) Many new laws and reqgulations have been made at this time by the American people against the british colonial rule prevailing that time in America 2) Secondly, the people in America refused to be under the dictatorship or British rule and actually merged to form the coalition of independent states without any interference from the British rules.

Explain what \"#include \" does in a source code? Solution The \"# include\" statement \"grabs the attention\" of the pre-processor (the process that occurs before your program is actually compiled) and \"tells\" the pre-processor to include whatever follows the \"# include\" statement. While the pre-processor can be told to do quite a bit, in this instance it\'s being asked to recognize a header file (which is denoted with a \".h\" following the name of that header, indicating that it\'s a header). Simpler words: The preprocessor reads the primary source file into memory, and scans for commands such as #include. ... The directive is for the preprocessor, which actually has very little to do with the C compiler except that they are always bundled togethe.

dN/dS ratios reflect patterns of genetic divergence that have accumulated between species over time. A dN/dS ratio of 1.0 is consistent with a neutral model of evolution. Look back at the relationship between dN and dS for both the lysin and VERL genes. What is the most likely hypothesis explaining the pattern that species with more distantly related gene sequences tend to have lower dN/dS ratios? Additional info: using MEGA software, it was found that the dN/dS ratio for lysin was 1.237 (positive selection) and the dN/dS ratio for VERL was about 1 (neutral selection). Solution dN/dS ratio is a statistical test to quantify selection pressure on protein coding regions of microbes. Two things taken into consideration here, rate of substitution at silent sites (dS- assumed neutral) and rate of substitution at non-silent sites(dN- positive). Because both the species are divergent from each other we observe lower dN/dS ratio. The sequesence which are present in the exsisting species are essential for their survival, so they can not afford to change the sequence. They have more distantly related gene sequences, so they do not have any similarity and do not need significant changes in the sequence..

Discuss the complexity of problem definition and the importance of accurate data to successfully apply quantitaive analysis in management. Solution The quantitative methods contain two component parts, the quantitative and method, with asymmetrical attention to the quantitative term. Speaking about method, interest is focused upon the so- called Scientific Method. Science is the mastering of things of the real world, by knowledge about the truth. The term method drives to dialogue on methodology in science which is clouded, as the phrase scientific method is used in two different ways. The one is very general, as a process of improving understanding. Although vague, it is considered as a powerful definition, since it leaves room for criticizing dogmatic clinging to beliefs and prejudices, or appreciating careful and systematic reasoning about empirical evidence. The other is the traditional sense, and supports that there is a unique standard method, which is central to identity of the science. In effect, scientific progress requires many methods, so there is not a unique standard method, though taught as a straightforward testing hypotheses derived from theories in order to test those theories. The more acceptable definition of scientific method is a process by which scientists, collectively and over time, endeavour to construct an accurate (that is reliable, consistent and non-arbitrary) representation of the real world. The popular hypothetic-deductive standard method is excluding consideration of the process of discovery in science. Rather, research is defined as a penetrating process of learning and understanding the substance of actual things and facts, by use of different methods. The research process incorporates formulation of a research issue and construction of a conceptual framework, by using all available information sources. The quantitative methods have a number of attributes, such as: they employ measurable data to reach comparable and useful results, assume alternative plans for achieving objectives, plan data, concerning observations collection, configuration and elaboration by statistical and econometric stochastic methods, check data reliability, choose appropriate sampling method, use carefully the estimates of the parameters for forecasting and planning purposes, etc. since they derive from ex- post data concerning past. In an increasingly complex business environment managers have to grapple with a problems and issues which range from the relatively trivial to the strategic. In such an environment the quantitative techniques have an important role. It is obvious that life for any manager in any organization is becoming increasingly difficult and complex. Although there are many factors contributing to this, figure 1 illustrates some of the major pressures making decision making increasingly problematic. Organizations find them selves operating in an increasingly complex environment. Changes in government policy, privatiz.

Which of the following is/are true regarding router operation? A. Routers work at Layer 3 only. B. Routers work at Layers 1, 2, and 3 to accomplish their tasks. C. Routers only examine Layer 3 addresses. D. Routers must examine the Layer 2 address to accept the frame first, and then will look at the Layer 3 address. Solution B and D are correct. All devices must work at the Physical layer, and the router must also examine the Layer 2 address to determine if the frame is intended for it or not. After the frame’s physical address is verified, the router moves up to Layer 3 and examines the IP address. A and C are incorrect. When a device is said to work at a given layer, it means the device works at all layers up to that level. Routers work at Layer 3; therefore, they perform functions at Layers 1 through 3..

What does the following statement mean: There is co-translation translocation on a growing polypeptide chain. Solution In a part of protein synthesis, as the signal sequence emerges from the ribosome, it is recognized and bound by SRP (signal recognition particle), which escorts the complex to the ER membrane and SRP directs both the binding of the ribosome to the ER membrane and insersion of the nascent polypeptide into the transmembrane channel. Then, translation resumes and the growing polypeptide chain is translocated across the membrane. This process of tranlational machinary halts for a while and translocate to the ER and where translation will resume. This process is called co-translation translocation on a growing popypeptide chain..

What are the two main points of the fluid mosaic model? What affects fluidity of the plasma membrane? Why is fluidity important? Describe the 6 functions of membrane proteins. Which two aspects of a membrane confer selective permeability? Compare channel and carrier proteins. Can channel proteins participate in active transport? Solution Fluid mosaic model was proposed by Singer and Nicolson to explain the selective permeability of the plasma membrane. According to it, plasma membrane is a mosaic of phospholipids, cholesterol and proteins. The proteins are embedded in the phospholipid bilayer. THe phospholipids have hydrophobic tail end and hydrophilic head. The mosaic nature of the plasma membrane helps it to be fluid. The fluidity is interrupted by occasional membrane proteins. The ratio of saturated to unsaturated fatty acids also contribute to the fluidity of the membrane. Unsaturated fatty acids \"kinks\" help the membrane to be fluid at low temperatures. Cholesterol also helps to keep the membrane in a uniform state of fluidity. Functions of membrane proteins include The size of the pores and hydrophilic/hydrophobicity prevents or allows the permeability of most of the molecules. the other important aspect which confer selective permeability to the cell is the membrane proteins Channel proteins are lipoproteins, while carrier proteins are glycoproteins. Carrier proteins can transport molecules or ions against the concentration gradient, while channel protein cannot. Carrier proteins move across the membrane, whereas channel proteins do not move while transporting molecules or ions. Carrier proteins can mediate both active and passive transport, while channel proteins can mediate only passive transport.

The haploid number of chromosomes for dogs is 39. How many TOTAL chromatids would be found in a normal somatic cell from a dog? Solution Ans. A chromosome and its duplicated copy (formed during S-phase of cell division) are called sister chromatid of each other; and form a chromatid-pair when together. A sister- chromatid pair separates into two independent chromosomes during anaphase. A chromatid is equivalent to one chromosome. Or, both the terms represent the condensed form of a single linear DNA but named differently depending on the stage of cell cycle.. Now, Total number of chromosomes in normal somatic cell = 2 n ; [n = haploid number] = 2 x (39) = 78 It is noteworthy that the term “chromatid” is restricted for “the condensed form of DNA during M-phase of cell division - as long as two sister chromatids are connected to each other”. In all placed except this, the term chromosome is used to represent the condensed form of DNA. That is, technically, a normal somatic cell does not have its DNA in form of chromatid, it’s in form of chromosome only. For the time being, it’s assumed that “chromatid” represents a “chromosome”. So, number of chromatids in normal somatic cell = 78.
