Answer:
Virulence, the capacity to cause disease, varies markedly among viruses. Some viruses cause lethal disease while others do not. For example, nearly all humans infected with rabies virus develop a disease of the central nervous system which ultimately leads to death. In contrast, most humans are infected with circoviruses with no apparent consequence.
Explanation: One explanation for viral virulence is that it facilitates transmission. However, a comparison of infections caused by two enteric viruses, poliovirus and norovirus, does not support this general view. Both viruses infect the gastrointestinal tract and are spread efficiently among humans by fecal contamination.
The Cusichaca Andina is the name of an organization, which is attempting to preserve a small, pink potato from the Andes, known as huana. It is considered one of the perfect crops for uncertain times, as it resists extreme rain, frost, and drought. It can be stored for two to three years.
The organization is also trying to revive the irrigation facility, which Incas utilized in the Andean region, and researching other conventional crops, like amaranth, quinoa, squashes, and potatoes.

Explanation:
Biology :- It is the study of living organisms, divided into many specialized fields that cover their morphology, physiology, anatomy, behaviour, origin, and distribution.
Biotechnology :-It is the use of biological systems found in organisms or the use of the living organisms themselves to make technological advances and adapt those technologies to various fields.
