Which statement below is true?
Active transport across the cellular membrane happens only when a molecule is too big to diffuse through the plasma membrane.
Active transport requires energy to move molecules against their concentration gradients.
Active transport requires energy in the form of ATP to move molecules directly through the phospholipid bilayer.
Active transport uses ATP for energy and nothing else.

What is the difference between a slime layer and a capsule?
Both are a type of glycocalyx, the slime layer is disorganized and loosely associated with cell while a capsule is organized and tightly associated.
Both are a type of glycocalyx, the slime layer is tightly organized while the capsule is disorganized.
A slime layer is a type of glycocalyx that aids in biofilm formation, while a capsule is a protein-based structure that provides protection.
A slime layer is a community of organisms living together, a capsule is a type of glycocalyx that surrounds only one bacterium.

Why must eukaryotes replicate via mitosis and meiosis, rather than binary fission?
Because they must shuffle their genome with every round of cell mitosis.
Because eukaryotes have multiple, linear chromosomes must be accurately sorted into daughter cells.
Eukaryotes use binary fission only when replicating for growth, not procreation.
Because Mitosis and Meiosis are clearly superior to binary fission.
