1.Answer: C

Light travels as a wave. But unlike sound waves or water waves, it does not need any matter or material to carry its energy along. This means that light can travel through a vacuum—a completely airless space. … It speeds through the vacuum of space at 186,400 miles (300,000 km) per second.

2.Answer: A

Gibberellins are growth hormones that stimulate cell elongation and cause plants to grow taller. Gibberellins also have a role in other plant processes, such as stem elongation, germination, flowering, and fruit ripening. … Once a plant releases gibberellins, its cells begin a process of elongation.

3.Answer: A

A sphygmomanometer, also known as a blood pressure meter, blood pressure monitor, or blood pressure gauge, is a device used to measure blood pressure, composed of an inflatable cuff to collapse and then release the artery under the cuff in a controlled manner, and a mercury or mechanical manometer to measure the pressure.

4.Answer: C

Synthetic diamond is also widely known as HPHT diamond or CVD diamond after the two common production methods (referring to the high-pressure high-temperature and chemical vapor deposition crystal formation methods, respectively).

5.Answer: A

Dry ice, sometimes referred to as “cardice” (chiefly by British chemists), is the solid form of carbon dioxide. It is used primarily as a cooling agent. Its advantages include lower temperature than that of water ice and not leaving any residue (other than incidental frost from moisture in the atmosphere).

6.Answer:  B

The upper part of the leaf is where the light falls, and it contains a type of cell called a palisade cell. This is adapted to absorb a lot of light. It has lots of chloroplasts and is shaped like a tall box.

7.Answer: D

The formula for sodium sulfate is Na2SO4.

8.Answer: B

Light travels very fast with a speed of 300 million metres per second in a vacuum. It takes only 8 minutes and 20 seconds for light to travel from the Sun to the Earth. Through the air light travels about a million times faster than sound.

9.Answer: C

It works based on principle of faraday law of electromagnetic induction. The faradays law states that whenever a conductor is placed in a varying magnetic field, EMF is induced and this induced EMF is equal to the rate of change of flux linkages.

10.Answer: D

Aspirin, also known as acetylsalicylic acid, is a medication used to treat pain, fever, or inflammation. Specific inflammatory conditions in which aspirin is used include Kawasaki disease, pericarditis, and rheumatic fever.
