Everyday Science 2013---Faislabad Re-exam
 

2) Briefly describe the role of nitrogen , phosphorous and potassium in the growth of plants. What are negative impacts of fertilisers?

3) Why long exposure of human skin to the sunlight is dangerous? What are various natural protections in our body against the harmful radiations in the Sunlight? Is there any positive impact of radiations?

4) Describe briefly the difference between. Conductors, semiconductors and insulators?

5) Give a brief account of use of radiation in medical diagnosis. Why MRI is preferred over CT scan or X-RAY imaging?

6)a) Why DDT once labelled as a miracle is now being considered an Environmental tragedy?
b) A large variety of deodorants mask the original odour of our body . Which body part produces the unpleasant smell and how it is produced?

7) Why people have switched to vegetable oil for cookin instead of saturated fats? Which of these two contain higher level of LDL? Is it HDL or LDL which is harmful to human health and why?

8) What are natural sources of vitamin D and symptoms of its deficiency in humans?
Why an indiscriminate use of antibiotics may prove dangerous?

9) Define Radioactivity . How alpha , beta and gamma radiations are produced as a result of decay of an unstable nucleus differ in their effects on living beings?



MCQS were real tough . I can't remember any repeated from Past papers , all were novel . About 25 from human physiology and zoology . Having attempted 2 EDS papers this year, I may give a piece of advice that the age of KASHMIRI and Bhatti is over in CSS EDS . Candidates should give a day per week to EDS like English , otherwise for art students EDS can be a tragedy now . Even people for medical backgrounds like me felt that EDS was difficult and especially MCQS.

Difficult paper indeed.

After going through all the past papers, I believe this paper is the toughest one

Both papers were tough this year , and MCQS of this re exam were the toughest .

Paper is tough but not toughest. Q- 4 & 9 are common questions

How Alpha , gamma and beta rays "differ " in their effects on living beings?

Well it's easy then nothing is tough in CSS .
And obviously one has to attempt 5 not 1 question .

In EDS only doctors claim to have upper hand because except Biology all subjects are wiped out. Especially , Geography is not the option for those who considered it helpful in EDS.

I think it was a revengeful paper set for the re-exam. Really, it was hard & different from the previous papers. May God help us all.

No question related to computer sciences
