Biological science includes two professional directions: biological science and biotechnology. It tends to use organisms for production, such as using genetically engineered bacteria for fermentation. Study the theory and technology used to guide practice, such as biological separation technology.
First of all, considering the relatively high flexibility of major setting in domestic colleges and universities, it is suggested that you should know more about the courses offered by your major or contact the main research direction of your school when filling in your volunteers. As far as I know, these two majors in many schools will offer the same courses, such as zoology, botany, biochemistry, molecular biology, genetics, etc., which constitute the main content of professional basic courses. In addition, there will be some more in-depth and small-scale specialized courses, and the contents of these specialized courses will constitute the main learning content in the future.
Secondly, it is the study of professional content. Personally, I think there is not much difference between the two majors at the undergraduate level. If there is an opportunity, I should go to graduate school for further study. For example, the biotechnology direction in the biological sciences will also recruit graduate students in the computer field, and many Daniel's teams will also have some students from other fields to work together. Undergraduate study is more like general education, and it is better to study professional knowledge seriously than to dwell on literal meaning. During college, you should read widely and choose the one that suits you best on the basis of fully studying your professional direction, instead of obsessing about literal meaning.
Finally, I hope you can choose your favorite direction.
