Cells are called the building blocks of life because they are the basic unit of all living organisms, and must be present for life to exist. Plants and animals have trillions of cells, while protests have only one cell, yet protests are still considered to be living organisms. Cells are the smallest unit of life that can reproduce independently.

If two or more forces act on a body simultaneously, the the total force on the body is called the net force or the resultant force. The net force is the vector sum of all the forces that act upon an object, i.e., it is the sum of all the forces, taking into account the fact that a force is a vector and two forces of equal magnitude and opposite direction will cancel each other out.

Examples of synthetic polymers include nylon, polyethylene, polyester, Teflon, and epoxy. Natural polymers occur in nature and can be extracted. They are often water-based. Examples of naturally occurring polymers are silk, wool, DNA, cellulose and proteins.

We know that plastic is non-biodegradable. This means that plastic waste is getting accumulated in our environment. Accumulation of plastic waste is creating a huge problem for us. Hence, we should avoid plastic as far as possible. We should switch over to biodegradable alternatives wherever possible. For example; we should use shopping bags made up of jute or cloth instead of plastic.

Fertility refers to the natural ability of a man or woman to produce an offspring. Infertility occurs when there are biological factors affecting this ability. Infertility is usually diagnosed by a doctor when a couple has been trying to conceive for 12 months or more. The main symptom of infertility is the inability to get pregnant. A menstrual cycle that's too long (35 days or more), too short (less than 21 days), irregular or absent can mean that you're not ovulating. There may be no other outward signs or symptoms.

The image formed by a plane mirror is always virtual (meaning that the light rays do not actually come from the image), upright, and of the same shape and size as the object it is reflecting. A virtual image is a copy of an object formed at the location from which the light rays appear to come.
The characteristics of an image formed in a plane mirror:
- image formed is virtual ie image cannot be projected or focused on a screen
- the distance of the image ‘behind’ the mirror is the same as the distance of the object in front of the mirror
- the size of the image formed is the same as the size of the object
- the image is laterally inverted i.e. left-right reversal of the orientation of the image
- altitude/orientation is always upright.
