1. An example of an organism in which the respiratory and circulatory systems are separate is the earthworm. Earthworms have a specialized respiratory system called cutaneous respiration, where oxygen is absorbed and carbon dioxide is released through their moist skin. Their circulatory system, on the other hand, transports nutrients and waste products through a network of blood vessels.

To find this answer, you can search for organisms that have separate respiratory and circulatory systems. An online search or consulting biology textbooks would provide detailed information about specific organisms.

2. An example of an organism with a closed circulatory system that is not used for gas exchange is the earthworm. Earthworms have a closed circulatory system called a closed circulatory network. This system transports nutrients, hormones, and waste products throughout the body using a fluid called hemolymph, which is similar to blood. However, earthworms rely on cutaneous respiration for gas exchange rather than using their circulatory system.

You can find this answer by researching organisms with a closed circulatory system and determining whether the system is used for gas exchange or not.

3. An example of an organism whose waste gases accumulate in one system but then move to another system for removal is the human body. In humans, waste gases like carbon dioxide accumulate in the bloodstream during cellular respiration. This carbon dioxide is then transported by the circulatory system to the lungs, where it is expelled during exhalation.

To find this answer, you can study the respiratory and circulatory systems in humans or other organisms to understand how waste gases are transported and removed from the body.

4. An example of a group of organisms in which some use a swim bladder for gas exchange outside of water is the lungfish. Lungfish are a group of fish that have both gills and lungs, allowing them to extract oxygen from water and air. Some species of lungfish use their swim bladder, a gas-filled organ, to supplement oxygen uptake from the air when they are out of water.

To find this answer, you can search for organisms that possess a swim bladder and investigate its role in gas exchange.

5. An example of an organism that changes from gill breathing to lung breathing as it matures is the amphibian, specifically frogs and salamanders. These organisms generally start their lives with gills, which they use to extract oxygen from water. As they undergo metamorphosis, they develop lungs and transition to lung breathing.

To find this answer, you can research the life cycle of amphibians or specifically look for information about frogs and salamanders and how they transition from gill to lung breathing.
