about 100 trillion
What crop helped Jamestown become economically successful?

The population increases.
What organelle contains the cell's genetic information and helps control its activities?

Give one issue that contributed to Bacon's Rebellion.
Acceptable responses include conflict over western settlement/land, conflict with Indigenous peoples, or disagreements with Governor William Berkeley's government.
What happens to helpful bacteria when a person takes antibiotics?
Antibiotics can reduce/kill helpful bacteria along with harmful bacteria.
What representative assembly was created in Virginia?

population remains stable.
What is the difference between a unicellular and multicellular organism?

Jamestown was established largely for economic/profit goals, while Plymouth was established by settlers seeking religious freedom.
Scientists notice the moon jelly population has increased. Why isn't knowing the number of births alone enough to explain the population change?
Scientists also need information about deaths (and relevant evidence) to determine how the population changed.
