How do Plants Breathe?

-
Like any other living organism, plants also breathe. They take in oxygen and release carbon dioxide by the process of respiration. The oxygen taken in is used for breaking down sugars that the plant makes during photosynthesis, and energy and carbon dioxide are released. This energy is used by plant for its growth and reproduction. About 40 per cent of the energy released is used up and the rest is lost as heat.

The idea quickly spread around  Flanders

Why are Some Animals Brightly Coloured?

-

A nimals with an unpleasant taste or which are poisonous, often advertise themselves with their bright colouring. The bright colours warn the predators to avoid these animals and keep them at a bay.

The distance around the Earth, that is, it's circumference around the equator is 40,091 kilometres. The diameter (the distance across the centre of the Earth ) at the equator is 12,756 kilometres. The Earth is slightly smaller when measured between the poles (12,713 kilometres), so it is not an exact sphere. If the Earth is weighted on a weighing machine, it would be nearly 6x10 tonnes.
