Book Description

Biology Grade 12 unit one Unit one Applications of Biology - Applications of Biology in our day-to-day Life is numerous.

- Biology is a science in charge of studying all living beings.

- It helps to understand every living organism from the smallest bacteria to the biggest blue whales.

- Biological science is very useful science to determine where some diseases and pests come from such as infections, animal pathologies and damages to plants.

- Biology covers the study of functions of living organisms, the evolution of species, the factors that produce diseases as well as the discovery of new drugs.

- This discipline allows human beings to explore topics such as genetic engineering, research applications with mother cells, and the global warming.

- It also helps to understand nature and how humans, animals and plants interact in life.

- Biology gives the vision of;  how living things evolve,  understanding the rate of extinction,  how species depend on and affects the habitats where it lives,  improving the effectiveness of conservation.

- A practical application of biology with which most people are familiar with is hand washing, domestication, and traditional fermentation.

- Regular soap washing removes acquired microbes from the skin and help control the spread of infectious diseases, - other applications of biology are in next topics.

Application in Conservation of natural resources - Conservation is the careful maintenance and wise use of natural resources to prevent them from disappearing.

- Natural resources are physical supplies that exist in nature (or actual and potential resources supplied by nature).

- These include soil, water, air, plants, animals, and energy.

- Conservation biology is a mission-oriented science that focuses on how to protect and restore biodiversity.

- Ethiopia has many natural resources, such as: gold, platinum, potash, limestone, natural gas, coal, etc.

- timbers, crop plants and coffee plantations.

- many different species of animals and plants, which make up rich ecosystems and - many different breeds of domestic animals.
