Answer 1

1. Flowers have colors and fragrances inorder to attract insects for pollination.

2. Decantation can be used to separate two immiscible liquids as they have different densities. When mixed, the liquid with lower density will be in the top and that can be poured off whereas the one with higher density which was in the lower layer remains in the container.
