active transport; passive or energy-requiring?
Correct Answers energy-requiring
albino corn has no chlorophyll. you would expect
albino corn seedlings to Correct Answers fail to

at the end of glycolysis, the original carbons of the
glucose molecule form what Correct Answers two
molecules of pyruvate
attachment proteins Correct Answers anchor the
cell membrane to the inner cytoskeleton, to
proteins outside the cell, and to other cells
,auxin Correct Answers light-sensing hormone
responsible for the curvature of plant shoots
towards light
