Solution
1. (a); The basic function of xylem is to transport waterfrom roots to shoots and leaves, but it also transports some nutrients.
2. (d); Speed is the distance travelled by object in a certain interval of time.Speed is not dependent on direction hence it is a scalar quantity.While Displacement, Momentum and Torque has both magnitude and direction, so they are vector quantity.
3. (a); The temperature at which a liquid freezes is called the Freezing Point. The freezing point of water is 32°F.
4. (a); A bit map (often spelled “bitmap”) defines a display space and the color for each pixel or “bit” in the display space. A Graphics Interchange Format and a JPEG are examples of graphic image file types that contain bit maps.
5. (b); Reduction is the loss of oxygen from a molecule or the gaining of one or more electrons.
6. (d); Most incandescent bulbs use tungsten (W) as a filament element. Tungsten is an inexpensive metal that has a long lifespan as a filament. It is a suitable option for incandescent bulbs because it has an extremely high melting point and is flexible. Pliable tungsten filaments are easily formed and hold up well against temperatures as high as 4,500 degrees Fahrenheit.
7. (a); Trees who shed their leaves once in a year most commonly in autumn is known as deciduous trees.Teak, Sisam, neem etc. are some examples of deciduous tree in India.

The EDS could be instrumental in implementation of 17 Sustainable Development Goals of the United Nations with minimum harm to the environment.
9. (b); Dynamite is an explosive made of nitroglycerin,
sorbents (such as powdered shells or clay) and stabilizers. It was invented by the Swedish chemist and engineer Alfred Nobel in Geesthacht, and patented in 1867. It rapidly gained wide-scale use as a safer alternative to black powder.
