a. True

When an electric current flows through a wire, it behaves like a magnet. „ A current carrying coil of an insulated wire wrapped around a piece of iron is called an electromagnet. The electromagnets are also used to separate

magnetic material from the junk.

b. True

The sun is considered the primary energy source since it is the source of nearly all the earth's energy. Plants produce food using sunlight, and the food we get from plants and animals also has its primary sunlight source.

c. False

No, the plastic bags do not get attracted by the magnet, so they cannot be separated by an electromagnet. Plastic bags are not magnetic materials, only magnetic materials like iron can be attracted by the magnet.

d. True

The basic unit of time is a second, and its symbol is s. Larger units of time are minutes (min) and hours (h). On the other hand, the basic unit of speed is meter per second m/s, which could also be expressed in other units such as m/min or km/h. The unit of time used depends on the need.

e. True

Pitcher plant is an insectivorous plant that derives nitrogenous compounds by trapping and consuming insects. The leaf of a pitcher plant is modified to form a pitcher-like structure. ... In this manner, pitcher plants fulfil their requirement of nitrogen by feeding on insects.
