Biology Revealed

Cellular biology studies cells and how they keep organisms thriving and alive through processes like homeostasis and reproduction which encourages cell growth, repairs damage, and creates new organisms. Macromolecules are essential in these processes because they provide energy, structure, and instructions. 

DNA guides how cells reproduce, grow, and function. Genetic variation plays a key role in the successful execution of these processes. Biotechnology is a way to combine these natural processes with human ingenuity to solve complex problems in the modern world. 

Plants teach us the basic laws of heredity, as discovered by Gregor Mendel. Through DNA analysis and other modern technology, scientists are able to learn more about what makes species and individual organisms unique. 

A rich and diverse food web supports biodiversity and makes our planet healthy and beautiful. Maintaining resilient ecosystems is crucial through the challenges of changing environments. As humans, we have an important role to play in supporting these processes and not causing more harm. 

Evolution did not happen only in the past, it is ongoing. As scientists study the world around us through tools like phylogenetic trees and DNA sequencing, they see the ways in which evolution is still shaping our world today. 

Careers in biology are diverse and rewarding. From medical research to wildlife conservation to teaching, the field of biology impacts our lives on a daily basis. The experts featured in this unit share their career journey and tips for students who are interested in pursuing biology as a career.
