Problem 4
Question
Tracheal systems are characterized by: a. closed circulatory tubes that move gases. b. spiracles that move gases between cells and body fluids. c. body movements that compress and expand air sacs to pump air. d. positive pressure breathing, which swallows air into the body. e. negative pressure breathing, which lowers air pressure at the respiratory surfaces.
Step-by-Step Solution
Verified Answer
The feature characterizing tracheal systems is closed circulatory tubes that move gases. Therefore, the answer is (a).
1Step 1: Analyzing the choices
Start with analyzing each option. The goal is to identify which one correctly describes the characteristics of tracheal systems.
2Step 2: Comparison with the Definition
Compare each of the given options to the primary characteristics of tracheal systems. Tracheal systems deliver oxygen directly to cells via branched, tube-like structures; they don't involve any 'breathing' in the way that larger organisms do, nor do they involve body movements to pump air.
3Step 3: Selection of correct choice
From these comparisons, it can be determined that option (a) 'closed circulatory tubes that move gases' correctly describes the method of gas exchange in a tracheal system.
