about 300 million years ago, the land of earth was in a single mass known as pangaea, as shown in figure a. about 150 million years ago, pangaea broke into the land masses shown in figure b. based on the diagrams, which of the following were more likely to survive on continent x after the breakup of pangaea than before it broke apart.

use lowercase letters
write true or false

1. organisms that lived in freshwater
2. organisms that required warm conditions
3. organisms that hibernated for long periods
4. organisms that traveled great distances during migration

Explanation:

1. After Pangaea split, continent X became isolated, but freshwater habitats are self-contained; these organisms don't rely on a large connected landmass, so their survival is more likely.
2. Continent X appears to move toward higher (colder) latitudes after the breakup, so warm-adapted organisms would struggle, not survive better.
3. In a now-isolated, potentially cooler continent, long hibernation helps organisms survive harsh, long seasons, improving their survival chance.
4. Migration over great distances requires connected landmasses, which are gone after the breakup, so these organisms would not survive better.

Answer:

1. true
2. false
3. true
4. false
