Having a bachelor of arts degree in biology means a person has completed all requirements set forth by an educational institution and has graduated. Essentially, a degree of any kind is a certification that the person is skilled in a chosen field and has the ability to continue forward.
A bachelor of arts in biology is a degree that focuses on courses in biology, while still offering students study in other subjects. It's a more broadly focused degree than a bachelor of science and often requires fewer biology courses overall.
A wide variety of careers are available to graduates with this degree including physical therapy, veterinarian, dentistry, and even nursing. Students seeking more research or academic positions may wish to consider a bachelor of science degree instead.
