- Question 1 of 7
1. Question
1 pointsCategory: Science and TechnologyWhich one of the following is a mixed fertilizer?
Correct
NPK is a mixed fertilize comprised of Nitrogen Phosphorous, and Potash (Potassium). Nitrogen helps plant foliage to grow strong. Phosphorous helps roots and flowers grow and develop. Potassium (Potash) is important for overall plant health. Urea, CAM (Calcium Ammonium Molybdate) and Ammonium Sulphate are straight fertilizers.

5. Question
1 pointsCategory: Science and TechnologyWhich of the following professional (s) are more likely to run the risk of a permanent change in their cell’s DNA?
- Researchers using Carbon-14 isotope
- X-ray technician
- coal miner
- Dyer and painter
Select the correct answer using the codes given below:
Correct
X-rays can damage the cell and tissues and finally cause mutation, even excessive dose can lead to cancer. Researchers using C-14 isotopes and coal miners too expose to the radiations released in less concentrations continuously may lead to mutation in their cell’s DNA.
