Arni University provides a variety of BSc courses. Six of these courses are provided through the university's School of Basic Sciences & Bio-technology. These specialisations are listed below:

1. BSc in Microbiology
2. BSc Medical
3. BSc Non Medical
4. BSc in Zoology
5. BSc in Botany
6. BSc in Forensic Science

Biology is the umbrella term for the scientific study of all living things. This includes animals, but also plants, fungi, and micro-organisms.
Zoology is a branch of Biology and is focused on animal life. This will include some microbiology (single-celled organisms) but is more focused on multi-cellular life (such as Daphnia and plankton), invertebrates (insects, Mollusca, etc.), and fauna (birds, reptiles, mammals, etc.).
Zoology curricula also include some Botany but in the context of animals. For example, how certain species of plants and animals interact with each other.

Zoology means - Animal Biology. It is a branch of biology. It deals with the animal kingdom, the structure, Embryology, Evolution, Classification, Habits, etc - both living and extinct, and how they interact with their ecosystems. 

You can become a Veterinarian after completing your graduation in Zoology subject. You can use your graduate degree to become a Vet Technician, to be precise.

By becoming a Vet Technician you can assist the veterinarian in major and minor procedures on animals as well as medical testing and checkups. But, to become a veterinarian, zoology majors should pursue a Doctor of Veterinary Medicine degree.

You have a plethora of options

• Biomedical science
• Ecology and evolutionary biology
• Animal behavior and neurobiology
• Cell and developmental biology
• General zoology
• Genetics
• Marine biology

You're not eligible for a BTech in Biotechnology program without Mathematics. BTech. Biotechnology requires you to have Mathematics as a core subject in class 12. The curriculum for a BTech in Biotechnology typically includes concepts mentioned below 

• Calculus
• Linear Algebra
• Probability and Statistics
• Numerical Methods

Biotechnology course is a highly complex discipline that demands intelligence, inventiveness, and, perhaps most importantly, patience and tenacity. You must stay current and actively seek opportunities to obtain hands-on experience and instruction.

You may work in a pressure-filled, frequently unpleasant workplace because many careers in Biotechnology focus on deadlines and time limits. After all, there is an ongoing demand for these life-altering medications, thus it is only fair that scientists are given strict timelines.

Some of the most popular Biotechnology key areas are mentioned below -
•    Medical Sciences
•    Clinical Engineering
•    Biomedical Engineering
•    Microbiology
•    Medical Engineering
•    Process Development Science
•    Clinical Research, etc.

Biotechnologist is not a medical doctor (MD). Biotechnologists usually hold degrees in Biotechnology, Biochemistry, molecular biology, or related fields, but they do not have medical sciences. 
The educational background and focus of a biotechnologist involve the application of biological and molecular techniques in areas such as research, industry, and the development of new technologies.
