Verified step by step guidance

Understand the concept of hemoglobin: Hemoglobin is a protein found in the blood of many animals, primarily responsible for transporting oxygen from the lungs to the rest of the body and returning carbon dioxide from the body to the lungs.

Recognize that most insects do not have hemoglobin: Insects typically have a different type of circulatory system called an open circulatory system, where hemolymph (a fluid analogous to blood) circulates freely within the body cavity. Hemoglobin is not commonly found in insect hemolymph.

Identify the exception among insects: While most insects do not have hemoglobin, the Chironomid midge is an exception. This insect is known to have hemoglobin in its circulatory system, which is unusual among insects.

Consider the function of hemoglobin in Chironomid midges: The presence of hemoglobin in Chironomid midges allows them to survive in low-oxygen environments, such as the bottom of lakes and ponds, where oxygen levels are lower than in the air.

Review the options given: Among the options provided (Anopheles mosquito, Chironomid midge, Honeybee, Housefly), the Chironomid midge is the correct answer as it is known to have hemoglobin in its circulatory system.
