Earth scientists have concluded that the methods of harnessing energy that have been used over the past two centuries, such as the burning of fossil fuels, are causing climates around the world to change more quickly and suddenly than ever before in human history. evidence includes increased temperatures in the air, rising sea levels, and the shrinking of ice glaciers at the north and south poles. the most complex level of organizational hierarchy that climate change could potentially affect is earth’s

a. biosphere
b. communities
c. organisms
d. populations

The many volcanoes located along the edge of the pacific ocean make up the ring of fire. how does subduction play a role in the volcanic activity in the ring of fire?

Ry was studying two populations of the same species of lizards. one population lived on an island and the other lived on the mainland. both populations were affected by a hurricane that hit the island and the mainland with equal force. a year later, henry was testing the gene frequency and saw a decrease in genetic variation in the island species, but not in the mainland species. which best describes a conclusion he might have reached? gene flow greatly affects small populations, but large populations can recover. genetic drift greatly affects small populations, but large populations can recover. gene flow greatly affects large populations, but small populations can recover. genetic drift greatly affects large populations, but small populations can recover.
