own sources of light.

Explanation:

• In a sentence, the subject is the noun (or noun phrase) that performs the action or is being described, and the verb is the action word (or state - of - being word) that tells what the subject does or is.
• For Sentence 1: "the water above" is what is doing the action of "exerting" pressure, so it is the subject, and "exerts" is the verb showing the action.
• For Sentence 2:
• In "life depends on hydrogen - sulfide", "life" is the subject (what is doing the depending) and "depends" is the verb.
• In "a poisonous chemical that releases energy...", "a poisonous chemical" is the subject (what is releasing energy) and "releases" is the verb.
• In "when it reacts with the oxygen...", "it" (referring to hydrogen - sulfide) is the subject (what is reacting) and "reacts" is the verb.

Answer:

(for Sentence 1):

• Underlined subject: $\underline{\text{the water above}}$
• Circled verb: $\boldsymbol{\text{exerts}}$ (already circled in the image, but for clarity, the verb is "exerts")
