Define nonconcordant variation: Why does nonconcordant variation make creating ‘race’ categories difficult? Why does clinal variation make creating ‘race’ categories difficult? Describe how genetic variation is distributed between and within human populations: Why does this distribution make creating ‘race’ categories difficult? Solution Part I If two pairs of genetically controlled traits are taken, then it is found that the two traits are not correlated to each other, for e.g. height and skin color are not at all related. Such type of traits is called as Non-concordant variation. So, one cannot predict the flow of traits from one race to another. Race categories are always defined on the basis of genetically related traits and variations between different traits. Now if there is no correlation, then defining of races will become difficult. For e.g. a tall man as well a short man or an average heighted man; all can have extremely fair complexion. So, you cannot associate the races of fair complexion, say Americans, with height. It is not compulsory that all tall people are fair, or all short people are dark. Part II Clinal variation: This is a change related to environmental variation like temperature change, altitude change, and change in levels of precipitation. If there is a gradual change in all populations with a particular environmental variation, then the type of variation is called as ‘clinal’ variation. One e.g. is number of counter folds in molar teeth. These changed gradually in all populations. So, you cannot distinguish one race from another on the basis of a clinal change. ‘Clinal’ change is a change which has occurred in all existing populations. Part III Genetic variation in humans is very diverse. The variations can occur due to single nucleotide changes (SNPs) or changes in multiple nucleotides. Let\'s talk about SNPs. There may be two copies of a single nucleotide at a particular position in one human being. On the other hand, there may multiple copies of the same nucleotide at the same position in another human being. I mean to say, in multiple human beings, multiple type of SNPs are found, all related to number of copies of the single nucleotide; creating variations among all species. There is no specific pattern of formation of SNP in a particular race, class or tribe. So, on basis of these SNPs, you will never be able to classify different races. Overall, there is no single formula to classify a race. Therefore, creating \'race\' categories is difficult..

Describe the operation of a tubular bowl centrifuge Solution Tubular-bowl centrifuges are used for the separation of solid-liquid and liquid-liquid mixtures by sedimentation. In these centrifuges, feed is introduced from the bottom of the bowl. A baffle assembly in the bowl accelerate the feed to rotor speed. The baffle isolate the feed to two different layers, i.e. based on the components in the feed introduced; this can be two liquid layers or liquid-solid layer. The heavier components are present in the outer layer and it becomes concentrated against the wall, while the light components are present in the inner layer, floating on the top. As the feed separates into layers, it travels up the bowl as an annulus. The top is located with overflow ports through which the liquid is discharged. Solid remains are recovered from the bowl manually..

Briefly discuss Philippa Foot’s contributions to virtue theory. Solution Philippa foot\'s contribution to virtue theory Philippa foot is an Oxford-trained British philosopher. She proposed the theory of virtue ethics. The virtue theory is based on the philosophy of Aristotle that a virtuous person is someone who has ideal character traits. This theory emphasizes on the importance of character and virtue rather than duty based or outcome based acts. Philippa foot’s contribution to virtue theory is elaborated below: Philippa foot has presented the views of Aristotle in a modernized way. She emphasized on the fact that goodness should be seen as the natural flourishing of humans as living beings. She also emphasized that ethics should be focused on making the world a better place to live in. The virtues of a person should be targeted for the betterment of an individual as well as society..

Write a C program that uses a recursive function to print a triangle pattern similar to Homework 7 - Using a Static Local Variable. The function will take two integer arguments, the first argument tells it how many asterisk characters (*) and a space characters that should be printed by the function directly and the second argument tells it the desired size of the triangle. The triangle pattern should be largest in the middle row, thus two lines should be printed directly by functions that make recursive function calls. It may be desired to use another function to print the lines For example calling the function as shown below, would print the output shown below it. triangle(l, 5); Solution #include \"stdio.h\" void triangle(int,int); void printLine(int,int); int main(void) { triangle(1,5); return 0; } void triangle(int c,int n){ static int flag=-1; if(flag<-1){ // base condition to break loop return; } else if(n<0){ // for printing second half printLine(c,flag--); triangle(c,n); } else{ printLine(c,flag++); // for printing the first half triangle(c,n-1); } } // print a line of astricks void printLine(int c,int n){ int i,j; for(j=0;j.

IT Project Management 1. Please compare and contrast a traditional waterfall-type approach to an agile method such as Scrum. 2. Explain the pros and cons of the differenent methodlogies and when they are best used such as PRINCE2, Agile methods, RUP framework and Six Sigma. Solution [1]Traditional waterfall -type approach 1.It is frequently much cost. 2.less bendable. 3.Risk is also extreme. 4.Unable to perceive the value upto the termination of project. Agile method such as scrum 1.Risk is not sa much. 2.It mainly targets on returning completely-tested ,individualistic and valuable. 3.Examinig cycle duration of agile is comparitively less. 4.it is known as people-centric procedure. [2] 1)pros and cons of agile methods Pros: 1.it is whippy. 2.it is a significant methodology in invention and software projects Cons: it is much hands-on procedure mostly for the stakeholders and project managers. 2.Pros and cons of six sigma pros:It recommends upgrade before faults reveals. Cons:Existing a data-driven assurance the six sigma is very inflexible. 3.Pros and cons of prince2 Pros:In high coorporate bodies ,the reporting needed to a prince2 assists with the perfomance assesments and also diminishing across some risks. Cons:If any modification in prince2 project ,it scoops for a team to adjust .since the procedure is totally clumsy with much documentation which is to modify. Pros and cons of RUP Framework Pros:It grabs the top slices of waterfall and assimilate into many computation procedure to permit the modification. Cons:It is much weighty process and able to operate on high poderously on stakeholder feedback.though it is a repetative procedure ,it is much steady for some kinds of projects..

What does it mean to destroy something at the molecular level in terms of chemical bonds? Solution Chemical bonds are broken by the energy that is released during the chemical reaction. This energy is created by the when electrons move from one molecule to another as they attempt to achieve a chemical balance. The breaking of chemical bonds can easily be identified because as are often accompanied by physical changes as the original elements used in the chemical reaction take on new forms or become new elements..

The mutations that make HIV resistant to specific drugs are usually.... a. substitutions (=non-synonymous mutations) b. silent mutations (=synonymous mutations) c. frameshift mutations d. mutations in the promotor region Please explain! Thanks Solution Answer: (a) Substitution Reverse transcriptase (RT) converts the RNA genome of HIV to DNA. The errors made during replication allow the virus to escape the cell\'s defence mechanism and also gives rise to resistance against anti-HIV drugs. Insertions and deletions (substitutions) in RT results in an increased error rate rate during viral replication..
