Answer:
When carbondioxide gas is emitted from vehicles and industries and goes upward in the atmosphere. The carbondioxide gas combines with the rain water forming an acid called carbonic acid and make the rain acidic.
When rainfall occurs this acid comes to the ground and ocean and adversely affected the living organisms due to acidic nature. The marine animal's body comprise of shell and skeleton. This skeleton and shell are made from calcium, when acidification of ocean water occurs, the calcium dissolved and the body of animals are destroyed.
The continental drift affects living organisms in that it causes changes in climates which puts selective pressure on organisms, causes changes in habitats, including when large amounts of shallow marine habitat were lost in the formation of Pangea. Additionally continental drift may cause an increase or decrease in competition among different species and also it happens so slowly that it does not affect living organisms
The time period was called the Hadean Eon, and the rocks themselves are nearly 4.4 billion years old
Mitosis results in the formation of two diploid cells while Meiosis results to the formation of four haploid cells. Mitosis is a process that takes place in the somatic cells; a cell that has doubled its genetic material divides to produce two diploid daughter cells while meiosis is a process that take place in the gamete cells where a doubled cell undergoes two rounds of division producing four haploid cells.
