  2. B
    luciferase, it
  3. C
    luciferase it
  4. D
    luciferase, which it

Cevap

luciferase; it
The correct answer correctly uses a semicolon to separate two closely related independent clauses. The clause before the semicolon ('This stunning light-producing reaction is catalyzed by the enzyme luciferase') and the clause after the semicolon ('it serves as a defense mechanism...') can both stand alone as complete sentences. Linking them with a semicolon is grammatically correct and conforms to standard English conventions.

Adım Adım Çözüm

1
Identify the clause structures on both sides of the blank.
The text before the blank ('This stunning light-producing reaction is catalyzed by the enzyme luciferase') is an independent clause. The text after the blank ('it serves as a defense mechanism...') is also an independent clause.
Determining whether the clauses are independent or dependent is necessary to apply the correct punctuation and linking rules.
2
Evaluate the transition and punctuation options to join two independent clauses.
Two independent clauses can be joined using a period, a semicolon, or a comma paired with a coordinating conjunction (FANBOYS).
This establishes the grammatical standard for connecting independent clauses.
3
Select the option that correctly implements one of these structures.
The option containing a semicolon ('luciferase; it') successfully links the two independent clauses without any errors.
A semicolon is the standard way to link two closely related independent clauses without a conjunction.
