Question

which type of sentence is this? astronauts can experience bone loss, muscle weakness, and diminished heart function when they are exposed to environments with reduced gravity for a prolonged period of time. simple compound complex compound - complex

Explanation:

To determine the sentence type, we analyze its structure. A complex sentence has one independent clause and at least one dependent clause. The main clause here is "Astronauts can experience bone loss, muscle weakness, and diminished heart function" and the dependent clause is "when they are exposed to environments with reduced gravity for a prolonged period of time" (introduced by the subordinating conjunction "when"). A simple sentence has only one independent clause, a compound has two or more independent clauses (joined by a coordinating conjunction), and a compound - complex has multiple independent and dependent clauses. Since this sentence has one independent and one dependent clause, it is complex.

Answer:

complex
