A slight increase in the temperature of the sea won't harm coral reefs. True or false? A. True
B. False

That statement is false.

Explanation:

Typically, a slight increase in temperature wouldn't just outright kill the corals. However, that slight increase will most likely weaken them.

Corals rely on algaes that live inside their tissues as their source of nutrients and energy. When the corals is experiencing a sudden slight increase in temperature, this algae will be expelled from the tissue. This make the corals unable to obtain the same level of nutrients/energy compared and weaken them.

first, the romans stayed isolated because they had to defend their own territories from neighboring cities that were harassing them, like the etruscans. second, once the romans managed to defeat their neighbors, and started to expand their territory, they started to build roads and bridges. finally, now that the romans have covered their territory with roads functioning as highways, they could mobilize their legions faster to assemble larger military units in a specific place
