Glaciers have caused erosion: On many U. S. beaches

In the Mississippi River

Around the Rocky Mountains

Along the coastline

(Will give brainliest!)

on many US beaches

Explanation:

glaciers cause erosion in two main ways, plucking and abrasion. they freeze to the bottom of the glacier and they are carried away by the flowing ice. abrasion is the process in which a glacier scrapes underlining Rock. the segments and rock Frozen in the ice at the bottom and slides of a glacier act like sandpaper

many other transport proteins, often called pumps, move materials against a concentration gradient. active transport drives molecules across a membrane from a region of lower concentration to a region of higher concentration. this process, shown in figure 5.1, uses transport proteins powered by chemi- cal energy.
