Explain a method how can you harvest rain water at home. Also write some activities in which you will utilize the
harvested water.

by using gutters to collect rain water

this is where u install gutters by the roof sides and always make sure they are clean for collection of clean water

when it rains put tanks below the gutters therefore the water will be collected

Explanation:

recycling of water-water after being used undergoes a process in which it is made clean again therefore can be used again.

reusing of water- this is where water is used more than once

example in the slums a person can use water for washing clothes to mop the house

they float because they are less dense than the water itself

something denser than water, like a rock, will sink to the bottom

1) gene flow

- it is described as the transfer of genes from one population to another population so that frequency of gene is increased.

-a zebra migrates to join a different herd of zebras.

2) natural selection

- a mechanism of evolutionary change in which individuals with advantageous traits survive and reproduce whereas the others ( those that can not adapt) eliminate from the population.

-competition for sunlight leads to taller trees.

3) mutation

- permanent change in the nucleotide sequence of dna ( genetic material) that could have harmful or useful consequences.

-the dna of a snake changes to make its venom stronger.

4) genetic drift - it is a random phenomenon ( that occurs by chance such as fire) that results in change in the gene frequency in a small population.    

-a grassfire randomly sweeps through a population of buffalo and kills most of the animals.
