thanks for helping me out.is this a verb or verb pharse. some species of sharks can grow new rows of teeth every week. A) can B)can grow C) grow D)can grow new rows (i say a but if wrong its b.)

"grow" is the main verb, and "can" is its auxiliary verb, so the complete verb (in this case a verb phrase) is "can grow"

To identify whether "can" is a verb or a verb phrase, let's break down the sentence and analyze the structure.

The sentence is: "Some species of sharks can grow new rows of teeth every week."

In this sentence, "can" is a modal auxiliary verb. Modal auxiliary verbs, like "can," "may," "shall," "will," "could," etc., are used to express possibility, ability, permission, or necessity.

However, "can" alone is not a complete verb phrase. In this sentence, the complete verb phrase is "can grow." "Grow" is the main verb, and "can" helps to express the ability of the subject (some species of sharks) to grow.

So, the answer is not A) "can," but B) "can grow." It represents the modal auxiliary verb "can" combined with the main verb "grow."
