Biology is the field of study of living beings and organisms, as well as their components, functions, and different behaviours. It consists of microscopical aspects such as proteins, genetics, and cells' function and structures, but also extends to bigger aspects such as organs, body systems, and ecology throughout the large environments.

​

Biology is intertwined in our everyday lives and impact our perception, understanding, and interactions of humans and their environments, other living beings, and themselves vastly. The studies of DNA, genealogy, cells and proteins help humans understand living beings, including themselves, at a small scale and be able to fine tune and treat issues that arise from it. DNA analysis could determine the ancestry and relatives of individuals, including animals and plants. The understanding of single-celled organisms and viruses help us combat different diseases and develop vaccines and cures that are crucial for public health today. Without the study of biology, the mortality rate of humans would've definitely stayed the same as what it had been centuries ago.

​​

Tying to the same topic, biology is also crucial for medicine, especially when paired with topics of chemistry and organic chemistry. All of the medicine we have today are built on biochemistry, a combination of organic chemistry with biology that is especially prominent in research and development of technologies regarding the compounds in the body and technology to affect the bodily functions (usually in a positive way).

​

Moreover, the applications of Biology also covers environmental, ecological, and conservational aspects. With biology, we are able to understand animals, plants, and how they work together to form an ecosystem. This is especially important nowadays with conservation efforts and the negative effects of climate change being an increasing threat to the Earth and wildlife.
