A biologist is a scientist who studies living things and how they act and react to the environments in which they live. Numerous types of biologists exist. These include research biologists, health care biologists, environmental biologists and biology educators.Know More
Research biologists study different groups of living organisms around the world. These types of biologists use state-of-the-art research techniques and tools to examine species such as micro-organisms, mammals, reptiles and amphibians in their natural habitats. Therefore, research biologists generally perform their work in exotic locations across the globe.
Health care biologists include physicians, veterinarians, nurses and dentists. These types of biologists prevent the spread of infectious and deadly diseases and formulate ways to enhance the health and well-being of their patients.
Environmental biologists seek out new ways to preserve the natural environments of different types of organisms. For example, zoo biologists study animals in captivity and design new preservation methods to help certain species live fuller, longer lives in their natural habitats. Conservation and management biologists further the work of these types of biologists by working with state and local authorities to develop laws and practices that protect the lives of groups of animals that cohabitate with humans or live near neighborhoods or urban developments.
Biology educators teach students and up-and-coming biologists basic and advanced biological sciences in classroom, laboratory and field settings.Learn more about Biology
All living things require a source of energy, nutrients, water, space to grow and reproduce, and a relatively stable environment that allows homeostasis. Many organisms also require oxygen, but this is not a universal requirement, and oxygen is actually deadly to certain organisms. Indeed, beyond these basic categories of needs, the requirements of organisms vary vastly from species to species.Full Answer >
A scientist who studies plants is called a botanist. Also called plant biologists, botanists study diverse plant life ranging from small microorganisms to giant trees. As experts in the field of botany, botanists are well-versed in the identification and classification of plant life, the biochemical functions and processes of plants and the various plant diseases and cures.Full Answer >
James Chadwick discovered neutrons in 1932, PBS states. Neutrons are the particles in an atom's nucleus that have mass but no charge. Chadwick proved their existence by tracking particle radiation.Full Answer >
Characteristics that all living things have in common are: growth, reproduction, they are made up of cells, they respond and adapt to their environment, and obtain and utilize energy. An organism must exhibit all of these characteristics to be classified as a living thing. However, living organisms can have different levels of cellular organization.Full Answer >
