Overview of B.Sc. Zoology
Zoology is the science of animals. It is the part of biology that studies the diversity of the animal world. It talks about the structure and life activity of animals, their distribution, their relationship with the environment, and the principles of their individual and historical development. B.Sc. Zoology course is closely connected to the industrial activity of man and to the mastery, rebuilding, and preservation of the animal world of earth.
Why Is Zoology Important?
A degree in B.Sc. Zoology is important for many reasons. For one, the study of animals and communities provides insight into how “life” works, and, consequently, how we work.
Many Zoologists are directly involved with the conservation of threatened or endangered species. The maintenance of biodiversity is considered, by many, crucial to our survival. Animals also have a great impact on our lives. They provide us with food, companionship, and a sense of wonder.
- Zoologists have contributed to the agricultural industry in many ways, with particularly significant contributions from entomologists enabling development of highly effective insect pest control techniques. Knowledge of the life cycles and reproductive habits of pests also allows safe storage of agricultural products for a much longer time and improves the quality of food products.
- A growing understanding of the habits and habitats of fish was a big part of the development of the commercial fishing industry in the 19th century, and the research of modern marine biologists and ichthyologists has led to the establishment of harvest limits and sustainable fisheries and improvements in aquaculture.
- Zoology has also made significant contributions to forensic science. Forensic pathologists can identify how long a body’s been buried based on the stage of the life cycle of the insects found on the corpse.
Fields in B.Sc. Zoology
- Anatomy: It is defined as the science of body structures and the relationship among them.
- Animal Nutrition: It is the branch that focuses on animal care, nutrition and animal feed science.
- Biochemistry: It is the study of chemical processes occurring in living beings.
- Biodiversity Conservation: Biodiversity conservation is about saving life on Earth in all its forms and keeping natural ecosystems functioning and healthy.
- Biophysics: It is the science of the application of the laws of physics to biological phenomena.
- Development Biology: It is the discipline that studies embryonic and other developmental process.
- Ecology: Study of animals and plants in relation to their habits and habitats.
- Etiology: It is the study of understanding WHY a certain disease manifests itself in the way it does. It is the study of what causes a disease.
- Evolutionary Biology: Branch of biology that deals with the descent by modification of plants and animals from earlier generations.
- Genetics: The scientific study of genes and heredity—of how particular qualities or traits are transmitted from parents to offspring.
- Molecular Biology: Molecular biology explores cells, their characteristics, parts, and chemical processes, and pays special attention to how molecules control a cell’s activities and growth.
- Cell Biology: It is the branch of biology that deals with the structure of a cell and the functions that are performed by it and its various organelles. It also talks about the inter relation between the various organelles.
- Paleontology: Study of the prehistoric life through its fossilized remains or the traces of its history in sediments.
- Physiology: It is the branch of biology in which we attempt to explain the specific characteristics and mechanisms of an organism’s body that make it a living being.
- Reproductive Biology: It is the branch of biology that studies about reproduction at different levels. It mainly involves the reproductive system and sex organs.
- Taxonomy: Taxonomy is the science of naming, describing and classifying organisms and includes all plants, animals and microorganisms of the world.
- Zoogeography: Zoogeography is the branch of the science of biogeography that is concerned with the geographic distribution of animal species.
- Morphology: The branch of biology that deals with the form and structure of organisms without taking in account the functioning.

Thanks for your article. One other thing is when you are disposing your property yourself, one of the troubles you need to be conscious of upfront is how to deal with house inspection records. As a FSBO supplier, the key concerning successfully transferring your property and also saving money upon real estate agent profits is knowledge. The more you recognize, the softer your property sales effort might be. One area that this is particularly critical is inspection reports.
Hvis folk ikke lukter lunta, og har det for travelt til Ã¥ klikke pÃ¥ lenkene, sÃ¥ kan de nok gÃ¥ pÃ¥ limpinnen.Selv luktet jeg jo lunta, men jeg mÃ¥ innrÃ¸mme at jeg ble glad og lettet da den ene etter den andre kinaputten smalt.Og sÃ¥ kommer Ã¸resuset og svien i Ã¸ynene – men etter en stund gÃ¥r jo det over…
