biology
The word 'biologie' is used in French to refer to the natural science that studies life and living organisms, including their physical structure, chemical processes, molecular interactions, physiological mechanisms, development and evolution, similar to 'biology' in English. It can be used in various contexts such as discussing subjects of study in school, talking about professions that involve studying life and living organisms, or in scientific discussions.
Biology is a fascinating science.
This sentence is fairly straightforward; it directly translates to 'Biology is a fascinating science.' The use of 'est' shows the verb 'to be' in French, while 'fascinante' is an adjective to describe the science of biology.
I love studying biology.
This phrase uses the verb 'adore' to express love for something, in this case, studying biology. The 'la' before 'biologie' is a definite article, which is always used before specific nouns in French.
Biology is related to chemistry.
In this sentence, 'liée' stands for 'related' and implies a relation between biology and chemistry. 'À' is a preposition that is used much like 'to' in English and is used here to link the two mentioned sciences.
