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.
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
Adrenaline, a natural stimulant created in the kidney's adrenal gland, travels through the bloodstream and controls functions of the autonomous nervous system, including the secretion of saliva and sweat, heart rate and pupil dilation. The substance also plays a key role in the human flight-or-flight response.Full Answer >
The function of the mucilaginous sheath of blue-green algae is to bind colonies together and to permit movement. The mechanism of this movement is not fully understood. The mucilaginous sheath is made of strands of cellulose and often bears pigments that give colonies of blue-green algae distinct colors.Full Answer >
Artificial embryo twinning is a method of making clones that mimics the natural process of creating identical twins, according to the Genetic Science Learning Center. It uses the same approach as natural cloning, but it is performed in a Petri dish rather than inside the mother.Full Answer >
Organisms have the ability to adapt to specific conditions within their environments through the biological process of variation, which enhance organisms' chances of survival. Variation is essentially a form of natural selection that takes place during long periods of time. Through the process of evolution, organisms retain the strongest traits and features that allow them to breed, find food, and survive in certain habitats.Full Answer >
