Explanation
Skull forms a protective covering for the brain . The main and overall function of the skull is to protect the brain and sensory organs and support facial structures.

Explanation
The brain , situated in the cranial cavity is an important internal organ. It is the control centre of our body. It controls the movements and all that we do. The brain is protected by the skull .

Explanation
The brain is the command center of the body, controlling everything from movement and sensation to thought and emotion. It processes information, sends signals to muscles and glands, and regulates various bodily functions, making it the central control system of the body.

Explanation
Science is the systematic study of the nature and behavior of the material and physical universe , based on observation, experiment, and measurement, and the formulation of laws to describe these facts in general terms.

Explanation
The word ‘ Scientia ’ is derived from the Latin word Scientia which means ‘ knowledge ’. It is the field of human knowledge concerned with facts that are explained logically by rules, patterns, or principles.

Explanation
Hepatitis is a disease of the liver , not the respiratory system. Top Common diseases of the respiratory system include: Asthma Chronic obstructive pulmonary disease (COPD) Pneumonia Influenza (flu) Tuberculosis (TB) Bronchitis Emphysema Lung cancer Cystic fibrosis Pulmonary fibrosis

Explanation
Vitamin A (specifically, retinal) is necessary for the formation of rhodopsin, a light-sensitive pigment in the retina of the eye. Rhodopsin is responsible for black-and-white vision and is found in the rod cells of the retina. Vitamin A deficiency can lead to night blindness , a condition where people have difficulty seeing in low light environments.

Explanation
Isotopes of an element have the same number of protons .

Explanation
A fasting blood sugar level of 99 mg/dL or lower is normal, 100 to 125 mg/dL indicates you have prediabetes, and 126 mg/dL or higher indicates you have diabetes

Explanation
Newton's first law of motion is also called as Law of inertia . Inertia is the ability  of a body by virtue of which it opposes a change. According to Newton’s first law of motion, an object will remain at rest or in uniform motion in a straight line unless acted upon by an external force. The inertia of rest : When a body is in rest, it will remain at rest until we apply an external force to move it. This property is called inertia of rest. The inertia of motion:  When a body is in a uniform motion, it will remain in motion until we apply an external force to stop it. This property is called inertia of motion.

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
