Angela was instructed on a test to make an analogy, or comparison, for polymers. She writes four examples of how polymers are like pearl necklaces. She has many parts to this analogy that make sense, but one part of her analogy does not fit. Which is the most likely error in her analogy?

The pearls are like monomers.
The thread that connects the pearls is like an ionic bond.
The entire necklace is like a polymer, or macromolecule.
Stringing the beads onto the thread is like polymerization.

Foreshadowing. the prologue states that this is the story of "star-crossed lovers." there are four strong foreshadowings of evil in act 1. identify at least two foreshadowings and explain their purpose.

Arotating space station is said to create “artificial gravity”—a loosely-defined term used for an acceleration that would be crudely similar to gravity. the outer wall of the rotating space station would become a floor for the astronauts, and centripetal acceleration supplied by the floor would allow astronauts to exercise and maintain muscle and bone strength more naturally than in non-rotating space environments. if the space station is 200 m in diameter, what angular velocity would produce an “artificial gravity” of 9.80 m/s^{2} 2 at the rim?

Which accurately compares concave and convex lenses?
