Our mineral needs are met from 

  1. Roughage

  2. Mineral water

  3. Mineral tablets

  4. Food


Correct Option: D
Explanation:

Our mineral needs are met from food. Minerals also help your body function. Some minerals, like iodine and fluoride, are only needed in very small quantities. Others, such as calcium, magnesium, and potassium, are needed in larger amounts. As with vitamins, if you eat a varied diet, you will probably get enough of most minerals.

Therefore, the correct answer is option D.

This trace element is needed for insulin to exert its maximal effect in glucose uptake

  1. Vanadium

  2. Chromium

  3. Molybdenum

  4. Selenium


Correct Option: B

Iodine stains

  1. Pectin

  2. Lignified regions

  3. Cellulose

  4. Starch.


Correct Option: D
Explanation:

Iodine is used in chemistry as an indicator for starch. When starch is mixed with iodine in solution, an intensely dark blue colour develops, representing a starch/iodine complex. Starch is a substance common to most plant cells and so a weak iodine solution will stain starch present in the cells. Iodine is one component in the staining technique known as Gram staining, used in microbiology. 

So, the correct answer is 'Starch.'

Sugar yielding part of Beta vulgaris is

  1. Leaf

  2. Shoot

  3. Root

  4. All the above


Correct Option: C
Explanation:

Sugar beetroots are processed into white sugar, pulp and molasses for food, feed or industrial applications. A typical sugar beetroot consists of 75.9% water, 2.6% non-sugars, 18.0% sugar and 5.5% pulp. In the sugar fraction, 83.1% is recovered as crystalline sucrose, 12.5% is recovered as molasses.

So the correct option is C.
