Question

two sets of structures are shown in each diagram. drag and drop to label each as homologous or analogous. answers may be used more once, once, or not at all.
human
bat
cat
preying mantis
analogous structures
homologous structures

Explanation:

Homologous structures are those that have a similar underlying anatomical structure due to common ancestry, even if their functions differ. In the first pair (human and bat), despite the human arm being for grasping and the bat wing for flying, they share similar bone - structures (humerus, radius, ulna, carpals, metacarpals, phalanges). Analogous structures have similar functions but different evolutionary origins. The cat leg (for walking/ running) and the preying mantis leg (for grasping and movement) have different anatomical structures (the cat has bones like the humerus - related structures, while the mantis has an exoskeleton - based structure) but may have some functional similarities in movement.

Answer:

Human - Bat: Homologous Structures; Cat - Preying Mantis: Analogous Structures
