The common cold and cholera are viruses. They begin with the letter c.
Scientists began to study artifacts to learn about past human societies, cultures, and behaviors. By studying artifacts, scientists can reconstruct the ways people lived, their technology, trade networks, and beliefs. This helps us understand human history and how civilizations evolved over time.
Eijkman did this because (at the time of looking for microorganisms) other scientists had recently shown that microorganisms caused a number of diseases and he thought that he had a chance to find beriberi was truly caused by a microogansm. :)

new viruses begin to be made
Some scientists think that viruses are not living organisms due to how simple they are. Viruses are usually nothing more than a strand of genetic coding with a protein coat. This makes them far more simpler than the simplest of organisms that use the standard cell structure which is rather complex.
Begin by studying "Hooked on Phones"
Viruses are not an organism at all. They are not alive. They are nonliving. They are like cockle burrs that "grab" hold of your clothing or a dogs coat. They are hijackers. Once they get attached to the cell of a living cell, they can take it over and "make" the living cell produce virus particles instead of cell parts. These parts can assemble into more viruses and then they breakout of the cell (killing it) and begin the process again. They can not make more viruses on their own. They are very small and can be considered microscopic. We have to use an electron microscope to see them as they are that small.

Infection with a pathogen does not necessarily lead to disease. Infection occurs when viruses, bacteria, or other microbes enter your body and begin to multiply.
Carcinogenesis usually begins with the accumulation of genetic mutations in a cell that lead to uncontrolled cell growth and division. These mutations can be caused by various factors such as exposure to carcinogens, radiation, or viruses.
