Question

q 13. a group of scientists hypothesizes how viral load increases in respiratory tissue over time. they hypothesize that tissue damage results from viral replication, not from the immune response. which experimental design best tests this hypothesis? compare tissue samples infected with a virus to those treated with antibiotics. test the tissues response to bacterial toxins instead of viruses. measure temperature and oxygen levels in infected tissue cultures. compare viral replication rates in tissues with suppressed immune cells versus normal immune function. clear all

Explanation:

To test the hypothesis that tissue damage results from viral replication (not immune response), we need to compare two scenarios: one where viral replication occurs (infected tissue) and another where immune - related factors (like bacterial toxins which might trigger immune - like responses) are introduced instead of viruses. If the damage in the virus - infected group is significantly different from the bacterial - toxin group, it can help support or refute the hypothesis.

Answer:

Test the tissue's response to bacterial toxins instead of viruses.
