Just about everything in the icy waters off the coast of Antarctica is in the same state—frozen. Yet one type of fish, called a notothenioid, remarkably does not freeze in the frigid environment. In a recent study, scientists were able to better understand a genetic alteration in the fish. As it turns out, antarctic notothenioids produce a substance that acts as antifreeze. Antifreeze is a term familiar to car owners. It is a substance that keeps the water inside an automobile engine from freezing. Notothenioids manufacture their own "antifreeze proteins." These proteins lock on to ice crystals in their blood.

the correct answer is c.

give me brainliest if it is correct!

if the italicized noun phrase is "the chairman", the correct option is s (subject). this noun phrase performs the syntactic function of subject of the main clause, as it preceeds the verb phrase ("heard") and is the doer of the action.

if the italicized noun phrase is "what was said about the program", the correct option is do (direct object). this noun phrase follows a transitive verb ("heard"), which requires a direct object to fully complete its meaning.

if the italicized noun phrase is "the program". the correct option is op (object of preposition). this noun phrase follows a preposition ("about"), which requires a prepositional object in order to complete its meaning.
