Question

A key should be parallel. An example of parallel choices is _____.

Answer 1

An example of parallel choices is a square peg fitting through the square hole and a round peg fitting through the round hole of a children's toy, representing the induced-fit model of enzyme-substrate binding in biology.

Step-by-step explanation:

An example of parallel choices is a square peg fitting through the square hole and a round peg fitting through the round hole of a children's toy. This analogy is often used to describe the induced-fit model of enzyme-substrate binding, which is a concept in biology where the enzyme changes shape to accommodate the substrate, similar to how the shaped pegs fit into their corresponding holes. This illustrates an important concept in biology that explains how enzymes are highly specific to the substrates they bind with.

Step-by-step explanation:

A parallel choice means that the sentence that have completely opposite meaning. The animal can fly and the animal can't fly.

An example of the parallel choices.

Both of the given sentences are opposite to one another. One sentence says that the animal can fly and the other sentence says that animals can't fly.

hence we can say that a key should be parallel.
