MCQs

Explanation
The series alternates between subtracting 1 and adding 2: 12 → 11 (subtract 1) 11 → 13 (add 2) 13 → 12 (subtract 1) 12 → 14 (add 2) 14 → 13 (subtract 1) Following this alternating pattern, the next step should be adding 2 to 13: 13 + 2 = 15 13 + 2 = 15

Explanation
Coal, fossil fuels, crude oil, natural gas, etc are all hydrocarbon fuels . These are called as non-renewable source of energy because they take millions of years to regenerate themselves. Water energy is renewable because it is regenerated by water cycle. Also wind energy and solar energy are renewable sources of energy.

Explanation
The cerebellum is a structure in the hindbrain. It coordinates movement, balance, and learning.

Explanation
Secondary consumers are organisms that eat primary consumers for energy.  In the above options, only goat is a primary  consumer. Primary consumers are herbivores, feeding on plants.

Explanation
Sound waves are longitudinal waves. When longitudinal waves travel through any given medium, they also include compressions and rarefactions.

Explanation
Dentist mirrors are typically concave mirrors. The examples of convex mirrors: Rear-view mirrors Blind Corner mirrors  Security mirrors

Explanation
The  Indian  Space Research Organization (ISRO)   is the national space agency of India.

Explanation
The most popular renewable energy sources currently are: 1.        Solar energy 2.        Wind energy 3.        Hydro energy 4.        Tidal energy 5.        Geothermal energy 6.        Biomass energy

Explanation
The roadway would cause diffuse reflection due to its rough surface some examples where diffused reflection Desert sand, disturbed water surface, and rough roads  

Explanation
Non-renewable energy sources : Oil Nuclear energy Petroleum Natural gas & coal Renewable sources of energy : Solar energy Wind energy Hydroelectric power Biomass energy Geothermal energy Tidal energy

Explanation
The nephron is the microscopic structural and functional unit of the kidney There are almost  1000000 of  nephrons in each kidney in the human body
