Question

In the late 1700s Edward Jenner developed the first vaccine from cowpox, an infectious virus found in cows. How do

viruses, like the one responsible for cowpox, cause disease?
By sexually reproducing with other viruses in the environment
By replicating inside the cell and then lysing the cell
© By gaining energy from metabolizing their food
By competing for water with cells of the Infected organism

Answer 1

Viruses cause disease by replicating inside host cells and lysing them.

Step-by-step explanation:

Viruses, like the one responsible for cowpox, cause disease by replicating inside the host cells and then lysing the cells. They attach to specific receptors on the surface of the host cell, enter the cell, and use the host cell's machinery to replicate their genetic material and produce more virus particles. Eventually, the host cell bursts open, releasing the newly formed viruses and causing damage to the infected organism.
