It is the broader branch of biology concerned with the origin, diversification, and adaptation of life forms on Earth. It also encompasses other disciplines of biology such as systematics, genetics, ecology, and paleontology. Some of the hot topics currently being studied are evolution speciation, ...
What are pathogens? a. Bacteria that help us digest our food b. Bacteria that break down material c. Bacteria that help our immune system d. Bacteria that can cause disease e. All of the Above How can microbes in foods be both helpful and harmful to humans?
This lesson will define bloodborne pathogens, give you some examples of ones you've likely already heard about, and describe how people are...
(Biology) An organism that lives and feeds on or in an organism of a different species and causes harm to its host. Pathogen Pathogens can spread through various means, including air, water, or direct contact. The pathogen causing tuberculosis spreads through the air when an infected person co...
What are the medical applications of the catalase test and Mannitol Salt Agar? Think of the detection of serious pathogens that can not be fully differentiated by Gram stain alone. Identify what the following bacteria would look like stained with the listed stain....
Pathogens are harmful organisms causing diseases, while microbes are diverse, including both harmful and beneficial microorganisms.
As we grow older, aches and pains can become a chronic part of life. But experts say it doesn't have to—and solutions are on the way.

The biology of human migration can be observed from the co-evolutionary relationship with infectious diseases. While many pathogens are brief, unpleasant visitors to human bodies, others have the ability to become life-long human passengers. The story of a pathogen's genetic code may, therefore, ...
The immune system relies on specialized "effector" T cells to fight off pathogens, but in chronic infections like HIV or cancers, the perpetual activation of these cells can turn them into "exhausted" T cells unable to continue fighting. ...
