Category Description: Science is a rigorous, systematic endeavor that builds and organizes knowledge in the form of testable explanations and predictions about the world. Modern science is typically divided into three major branches: natural sciences (e.g., physics, chemistry, and biology), which study the physical world; the social sciences (e.g., economics, psychology, and sociology), which study individuals and societies; and the formal sciences (e.g., logic, mathematics, and theoretical computer science), which study formal systems, governed by axioms and rules.
Q1. What is the normal temperature of human body?
Q1. What is the normal temperature of human body?
Answer: (A) 37°C
Answer: (A) 37°C
Answer: (A) 37°C
Normal body temperature is considered to be 37°C (98.6°F); however, a wide variation is seen. Among normal individuals, mean daily temperature can differ by 0.5°C (0.9°F), and daily variations can be as much as 0.25 to 0.5°C.

Q3. Identify the normally radioactive material in the following list.
Q3. Identify the normally radioactive material in the following list.
Answer: (A) Plutonium
Answer: (A) Plutonium
Answer: (A) Plutonium
Plutonium is the only radioactive element in the list.
Plutonium is a radioactive, silvery-gray, metallic element with the symbol Pu and atomic number 94. It has a high surface tension and viscosity compared to other metals, and tarnishes when exposed to air. Plutonium is created in a reactor when uranium atoms absorb neutrons, and is a by-product of nuclear power plants. It is the main fuel in fast neutron reactors, and more than one-third of the energy produced in most nuclear power plants comes from plutonium. Plutonium has five common isotopes, each with a different half-life, which is the time it takes to lose half of its radioactivity

Q4. Beyond what distance a normal eye can see objects clearly?
Q4. Beyond what distance a normal eye can see objects clearly?
Answer: (C) 25 cm
Answer: (C) 25 cm
Answer: (C) 25 cm
For a clear vision, the image must be on the retina. The image distance is therefore fixed for clear vision and it equals the distance of retina from eye lens. It is about 25 cm for a grown up person. A person can theoretically have clear vision of an object situated at any large distance from the eye.

Q9. Why the sky appears blue?
Q9. Why the sky appears blue?
Answer: (C) Dispersion of light
Answer: (C) Dispersion of light
Answer: (C) Dispersion of light
Blue colour of the sky is due to dispersion or scattering of light. The two most common types of matter present in the atmosphere are gaseous nitrogen and oxygen. These particles are most effective in scattering the higher frequency and shorter wavelength portions of the visible light spectrum.

Answer: (A) Marie Curie
Answer: (A) Marie Curie
Answer: (A) Marie Curie
Marie Salomea Skłodowska–Curie
She was the first woman to win a Nobel Prize, the first person to win a Nobel Prize twice, and the only person to win a Nobel Prize in two scientific fields. Marie won her 1st Nobel Prize in 1903 in Physics with her husband for their pioneering work developing the theory of "radioactivity" - a term she coined. Marie won her 2nd Nobel Prize in 1911 in Chemistry for her discovery of the elements polonium and radium, using techniques she invented for isolating radioactive isotopes.
