Gravity or weight Gravity is defined as the force of attraction exerted by the earth on a body towards its centre is called force of gravity or weight of the body. It is vector quantity. The SI unit of it is Newton(N). This relation shows that greater the mass of the heavenly body greater will be the force of gravity given by it. As the gravity increase the weight of a body also increase. Gravity of a heavenly body is inversely proportional to the square of the radius of that heavenly bady. Effects of gravity 1. We can stand,walk, play and perform other activities freely on the earth due to its gravity. 2. The rivers flow up to down due to the gravity. 3. The earth is covered by the atmosphere. 4. All types of objects thrown upwards return to the earth's surface.

Those animals which have no backbone or vertebral column are called invertebrates. They are classified into nine phyla. Characteristics of the animals of these phyla are given below: 1. Phylum: Protozoa i. They are unicellular organisms. ii. They are mostly found in water. iii. These animals have pseudopodia, flagella or cilia for locomotion. iv. They can be free living or parasitic. Some examples: amoeba,paramecium etc 2. Phylum: Porifera i. Porifera means pore bearer animals, commonly called sponges. ii. Most of them are marine organisms except spongilla. iii. They are diploblastic animals. iv. They respire through general body surface. V. They do not move from place to place, so they are called sessile. vi. The presence of calcium and silicon makes their body rigid and strong. vii. Sponges have two types of openings on their body surface i.e. ostia(mouthlets) and osculums(anus). Some examples: sycon, spongilla,euspongia etc. 3. Phylum: Coelenterata i. The body of ...
