Correct Answer: Vitamin K
Explanation:
Most of the Vitamin K is synthesized by intestinal bacteria in the large intestine.
Correct Answer: Narendranath Dutt
Correct Answer: to reduce heat loss by radiation
Explanation:
Polished surfaces are poor radiators of heat. So loss of heat on that account is reduced and the electric iron remains hotter than otherwise.
Correct Answer: Rocket technology
Explanation:
Cryogenic Engines find applications in Rocket technology. A cryogenic rocket engine is a rocket engine that uses a cryogenic fuel or oxidizer, that is, its fuel or oxidizer are gases liquefied and stored at very low temperatures. Notably, these engines were one of the main factors of NASA's success in reaching the Moon by the Saturn V rocket.
Correct Answer: Polarisation
Correct Answer: Lively and active
Correct Answer: Fungus
Explanation:
Yeast used in making bread is a Fungus.
Correct Answer: Japan
Explanation:
India finalised an Open Skies Agreement with Japan, allowing designated airlines of both signatory countries to operate freely. This is likely to be formalised during Japanese Prime Minister Shino Abe?s visit to India later this month. The agreement may allow airlines from Japan to fly directly to Chennai and Bengaluru.

Correct Answer: the time of ascent < the time of descent
Correct Answer: 10^16 mts
Explanation:
Light year is the unit of to express astronomical distances, that light can travel in one year. Light moves at a velocity of about 300,000 kilometers (km) each second. So in one year, it can travel about 10 trillion km. More precisely, one light-year is equal to 9,500,000,000,000 kilometers.
Approximately, 1 light year = 10^16 mts.
