Question

1. scientists are designing new medicines to fight infectious diseases caused by viruses. one of the most effective ways these medicines could limit the spread of the virus within the body would be to -

prevent viruses from dividing
make it easier for viruses to leave cells
stop viruses from attaching to cells
burst cells infected with viruses
clear all

Explanation:

To limit virus spread, preventing attachment to cells stops infection initiation. Viruses need to attach to host cells to infect them. Preventing division (viruses don't divide like cells), easing exit or bursting infected cells wouldn't limit spread as effectively as stopping attachment. So the most effective way is to stop viruses from attaching to cells.

Answer:

stop viruses from attaching to cells (the option corresponding to this statement in the original question's choices, e.g., if it's the third option, write "C. stop viruses from attaching to cells" assuming the options are labeled A - D with A as prevent viruses from dividing, B as make it easier for viruses to leave cells, C as stop viruses from attaching to cells, D as burst cells infected with viruses)
