Keeping you warm is not a function of sweat.it is soppose to keep you cool when you start to heat up.
When i observe internal parts of plants , i feel that its structure and functions are very complex and dependent from one another
If one part of the plants fail to do its function, it will be most likely that other parts of the plants will be disturbed too
hope this helps
The answer to the question is option C
The atmosphere is divided into different regions, called layers. The layer closest to the surface is known as troposphere, after which comes the stratosphere. The stratosphere begins at an altitude of 10 miles above the surface of the earth and stretches up to 31 miles above the surface of the earth. It is the second layer of the atmosphere (beginning from the surface of the earth) and it is the region which contains ozone, which plays a vital role in stopping ultraviolet radiation from reaching the earth's surface.
