2. Question
1 pointsCategory: Science and Technologywhich of the following would lead to ‘malnutrition’ ?
- overnutrition
- undernutrition
- imbalancednutrition
Select the correct answer using the codes given below:
Correct
Malnutrition defines a condition that occurs when the body is not getting enough nutrients. Whether resulting from an independent or unbalanced diet, digestive or absorption problem or other medical conditions. Overnutrition , under nutrition and imbalanced nutrition are three forms of malnutrition. Protein energy malnutrition PEM leads to two type of disease viz., marasmus and kwashiorkor ‘marasmus’ is a type of pem caused by simultaneous deficiency of protein and total food calories; whereas ‘ kwashiorkor’ is caused by serve protein deficiency.

3. Question
1 pointsCategory: Science and Technologywhich one of the following element is alloyed with iron to produce steel which can resist high temperature and also have high hardness and abrasion resistance?
Correct
The hardness of steel is proportional to percentage of chromium present. Chromium is alloyed with iron to produce steel which can resist high temperature and also have high temperature and also have high hardness and abrasion resistance. It is called stainless steel.

4. Question
1 pointsCategory: Science and TechnologyConsider the following statements:
A person in a spaceship located half way between the earth and the sun will notice that the
- Sky is jet black stars do not twinkle
- stars do not twinkle
- Temperature outside the spaceship is much higher than that on the surface of the earth
Of these statements:
Correct
Stars do not appear twinkling in the space because of absence of atmosphere, wind and air currents which changes the position of images of stars to make them appear twinkle
Sky appears jet black because of absence of scattering of light due to gas molecules in the space. Temperature will be higher as we get closer to the Sun.
