Explanation:

A complex sentence has one independent clause and at least one dependent clause. "I love all kinds of seafood, but shrimp is my favorite." is a compound - sentence (two independent clauses joined by a coordinating conjunction "but"). "Carl needs to find his cell phone, or he may borrow mine." is a compound - sentence (two independent clauses joined by a coordinating conjunction "or"). "When we are ready to leave, we will send you a text message." has a dependent clause "When we are ready to leave" and an independent clause "we will send you a text message". "If she starts to get warm, Janna will turn on the air conditioner." has a dependent clause "If she starts to get warm" and an independent clause "Janna will turn on the air conditioner". "Before you eat the sandwich, please cut it in half." has a dependent clause "Before you eat the sandwich" and an independent clause "please cut it in half".
