Question

select all that apply
select all the features present in arthropods.
pseudocoelom
jointed appendages
closed circulatory system
segmentation
exoskeleton that must be shed

Explanation:

• Arthropods have jointed appendages which aid in movement, feeding, etc.
• They show segmentation where the body is divided into distinct segments.
• They possess an exoskeleton made of chitin. As they grow, this exoskeleton (which does not grow) must be shed (a process called molting).
• Pseudocoelom is not a feature of arthropods (they have a true coelom).
• Arthropods have an open circulatory system (not a closed one where blood is always in vessels).

Answer:

• jointed appendages
• segmentation
• exoskeleton that must be shed
