Answer:

Vaccinations

Explanation:

For example, if a disease has an R0 of 18, a person who has the disease will transmit it to an average of 18 other people.

vodomira [7]

Answer:

b. Some carbon dioxide will move from chamber A to chamber B.

Explanation:

The two chambers are separated from each other by a separator that exhibits the properties of the cell membrane. It means that the separator film is semi-permeable in nature. The concentration of CO2 in the chamber A is 80%. This is relatively higher than its concentration in chamber B (20%). The concentration gradient will drive the passive diffusion of some of the CO2 from chamber A to chamber B so that the concentration becomes equal in both the chambers.
