The disturbance is perpendicular to the direction of the wave motion (propagation direction).
Best visualized on a rope whose one end you start agitating. This gives rise to waves running (propagating) forward, away from that end. While that is happening, if you look at the individual points on the rope you will see that they are not moving in the forward direction but rather they oscillate up and down (disturbances). The up-down direction is perpendicular to the direction of the forward wave propagation.
Answer:
III only
Explanation:
The ozone layer is extremely important for the living organisms on Earth. It is a layer that manages to stop big portion of the UV radiation from reaching the surface of the Earth, thus minimizing its negative effects, and only letting enough of it to be useful for the living organisms. If the ozone layer is removed though, then the UV radiation will be so high that most of the living organisms on land would die out because they can not stand such high levels of UV radiation. The marine organisms will also be badly effected, and the majority of them will also die out because of too much radiation, thus making enormous damage to the life on the planet.
I'm not 100% sure on this but in Ancient India, they used the caste system. This separated society into groups. The head of the household would always be the male and it was very patriarchal. When they had children, the mother would be in charge of domestic duties.
