What are arguments for and against a user program building additional definitions for existing operators, as can be done in Python and C++? Solution Answer: User can define his/her own types, and make them feel like native types by implementing operator functionality to meet his/her defined type requirements.Well this was good part. the bad part is the programmer can implement those operator to do something that is not intuitive to the user, for example, you can implement your own Integer type. The user would expect that the + operator would add two Integers ,but you can implement the + operator to do anything you want, like subtracting, not adding..

Explain the concept of diaspora and distinguish between voluntary and involuntary diaspora? Discuss the dynamics of diaspora and show the extent to which diaspora is a global phenomenon? Solution The concept of Diaspora: This phenomenon explains dispersed population scattered from their specific homelands but they maintain their cultural aspects in the country where they migrated. Diaspora is going to illustrate about the people themselves or their previous ancestors & the people who have been living are going to retain their cultural aspects with “memories/myths” about their specific homeland. The voluntary migration of population from their homeland where they are not forced to migrate known as “voluntary Diaspora” where, “you will find no force to migrate”. The involuntary migration of population from their homeland where they are forced to migrate known as “involuntary Diaspora (refugees migrate)” where, “you will find force to migrate” (mainly religious persecutions). According to Wilbur Zelinsky, the dynamics of Diaspora is mainly due to immigrants & emigrants and the extent to which Diaspora is a global phenomenon is explained mainly by rural and urban migration. These dynamics can be explained by data that collected & correlates to extent of migration rates specifically within a country over a period..

Does S_2 span P_2 ? Solution lets calculate the dimension of S_2 It is clear S2 is a subspace of P2 since every element of S2 is in P2. So if the dimension of S2 is 3 i.e. all elements of S2 are linearly independent then S2 spans P2 and it is a basis for P2 otherwise Not. Now lets see if all elements are LI if c1 (x^2 +1) + c2(x^2 + x) + c3(x+6) = 0 (zero polynomial) then c1 = -c2 c1 = -6c3 c2 = -c3 which gives all c1,c2,c3 = 0 so they are linearly independent and hence its a basis for P2..

Describe one exception to Mendelian inheritance In what year did Charles Darwin publish The Origin of Species? What is the diploid # in humans? Write the Genus and species names of our species in the proper form. Solution 1. It is now understood that inheriting one allele can, at times, increase the chance of inheriting another or can affect how and when a trait is expressed in an individual\'s Phenotype. Likewise, there are degrees of dominance and recessiveness with some traits. The simple rules of Mendelian inheritance do not apply in these and other exceptions. They are said to have Non- Mendelian inheritance Patterns. For example: ABO blood type in humans, Genes regulating human stature etc, 2. Origin of species by charles Darwin got published in 1859. 3. For humans a diploid species, n=23. A typical human somatic cell has 46 chromosomes. 4. genus: Homo Speices: H. sapiens..

Describe Norman’s 7 Stages of Action and Four Principles of Good Design Solution Answer : When we try to achieve something , we come accross many hurdles. There are alot of hurdles between your goal and initial step. Norman defined 7 stages of action which simulates it all. Here are the 7 stages of action : 1. Forming the goal 2. Forming the intension 3. Specifying an action 4. Executing the action 5. Percieving state of world 6. Interpreting state of world 7. Evaluating the outcome. First stage is for activity design. Next 3 are for interaction design and last three are for information design. The four principles of design are : 1. Contrast 2. Repetition 3.Alignment 4.Spelling These all are interconnected with each other..

An experiment was conducted to determine whether a deficiency of carbon in the soil affects the phenotype of pass . Listed below are the phenotype codes where . Solution Here, n = number of observations = 14 mean = sum of observations / total number of observations. mean = 29 / 14 = 2.071429 = 2.1 Median procedure : Arrange observations in ascending order. n = 14 (even) median = [ (n/2)th observation + (n/2 + 1)th observation ] / 2 n/2 = 14/2 = 7th observation n/2 + 1 = 8th observation median =[ 7th observation + 8th observation ] / 2 = ( 2 + 2 ) / 2 =2 mode is the most repeated value in the data set. Mode = 2 because 2 occures 5 times. Mode is 2. All the measures of center make sense since the data is numerical. Mid range = (maximum of data + minimum of data) / 2 Mid range = ( 4 + 1 ) / 2 = 5 / 2 = 2.5 Which of the following is not a characteristic of the mean. the mean is sensitive to outliers..

An abject is orbiting the Earth at 215 miles in altitude. It takes one hour to orbit the Earth. What is it\'s speed? What is the mathmatic equation to calculate the answer? Solution We know the earth\'s radius = 3960 miles. and the radius with object = 3960 miles + 215 miles = 4175 miles and the circumference of earth with respect to object = 2pi*4175 miles = 26232 miles and Given time = 1 hr then speed = distance/time = 26232 miles/1 = 26232 mph.

A protein that was isolated by a team of university scientists is suspected to be expressed on a yet to be identified lymphocyte. Outline a series of experiments that you would design to identify the cells expressing the protein. Solution The protein expressing gene is identified on DNA. The gene of interest and the plamid are cut with same restriction endonuclease. The obtained gene is inserted in the plasmid. The plasmid is transformed into cell line. The transformed plasmid containing a marker gene such as antibiotic resistance gene or LacZ is useful to screen the presence of newly transformed gene. Screening for the presence of desired gene is done by hybridization or other molecular techniques. The desired gene expression can be studied by gene knockout or RNA interference..

Why do sterols work as rigidity buffers in the cell membrane? Solution Sterols are essential in all eukaryotic cell membranes. Sterols reduce membrane fluidity and permeability, and increase membrane rigidity and strength. Together with sphingolipids they help organize regions of the membrane into lipid rafts, microdomains in the plasma membrane with increased rigidity, that organize cell signaling proteins into functional complexes..

What are two possible causes of B12 deficiency? Provide a detialed answer with literature review source. Solution Answer: Vitamin B12 is not synthesized by the body, and thus requires intake of animal foods rich in vitamin B12 or through supplements. Vitamin B12 helps in production of DNA and RNA, and works in concert with folic acid to make RBCs. Two possible causes of Vitamin B12 deficiency are: 1. Thinning of the stomach lining due to atrophic gastritis: Atrophic gastritis is often caused by the H. pylori. The bacterial infection frequently occurs during childhood and gets worse over time if it isn’t treated. Direct contact with the feces, vomit, or saliva of an infected person can spread the disease. It may also occur after eating food or drinking water that’s contaminated with the bacteria. When autoantibodies attack healthy stomach cells, autoimmune atrophic gastritis develops. These antibodies target the gastric juice producing stomach cells. These antibodies may also attack intrinsic factors, which are proteins released by stomach cells that help in vitamin B12 absorption. A lack of intrinsic factor results in pernicious anaemia, and low vitamin B12 levels in the body. (MLO Med Lab Obs. 2007 Feb;39(2):28, 30-1. Gut. 1964 Feb;5:27-37.) 2. Removed of part of the stomach or small intestine through surgery, including weight loss surgery: Bariatric surgery involves gut manipulation that alters the natural absorption of nutrients, thus nutritional deficiencies can develop. The most common deficiencies are vitamin B12, folate, zinc, iron, copper, calcium, and vitamin D and can lead to secondary problems, such as osteoporosis. Dietary supplementation are often given following surgery to avoid deficiency complications, although deficiency symptoms may be evident after months of surgery. Bariatic patients are at increased risk as their digestive have undergone alteration such that it interferes with the absorption of vitamins. (Curr Drug Metab. 2012 Nov; 13(9): 1345–1355. Pediatr Clin North Am. 2009 Oct; 56(5): 1105–1121.).
