The twenty-first century will be that of biology, a revolutionary science. Whether specialized in microbiology and immunology, molecular and cellular biology, physiology or biodiversity, ecology and evolution, the holder of a degree in biology can work as a consultant or research assistant in government departments or an academic, hospital, or other research centers or consultancies.

The biologist can go on to higher education to pursue a career in research or higher education. Biological sciences can examine life to understand how organisms work and adapt to their environment.
