Individuals who contract a disease caused by a strain of a drug-resistant bacteria are at risk. This is because, when they are treated with certain antibiotics,
![](https://reviewgamezone.com/pages/web/uploads/650c365bc4216_1695299163.png)
a) the resistant bacteria survive in greater numbers and pass the trait to their offspring
b) the beneficial bacteria are unaffected, rapidly reproduce, and destroy the resistant bacteria
c) the resistant bacteria are killed only by increasing the dose of antibiotics

Which ecosystems are most likely to remain stable over time?
![](https://reviewgamezone.com/pages/web/uploads/650c365bc4236_1695299163.png)
a) fresh water and seawater because more species in an ecosystem increases the variety of genetic material available
b) fresh water and seawater because an increased number of species causes salt concentration in the water to increase
c) brackish water and seawater because high salt concentration increases the number of species in water ecosystems
d) brackish water and salt lakes because salty water damages DNA, which results in fewer species surviving
