What is biology? What is chemistry? Are these hard subjects?
Biology is the study of living organisms and it is divided into different parts for example botany, zoology genetics,reproduction,physiology and ecology.
Chemistry is the study of matter and elements.it is divided into 5 parts:Analytical ,physical,organic ,inorganic and biochemistry.
Both of these subjects are not that tough nor too easy.it depends how much interest you take in them.
I think the one aspect of both disciplines that students find hard is that they both require memorization of a large number of terms and processes.
