Question

Classify the structures as homologous or analogous , depending on their structure and function

Answer 1

ANALOGOUS:

- The limbs of a bat and the forelimbs of a bird have similar functions but different anatomy.

- The wings of a bird have a skeletal structure, but the wings of bees do not.

HOMOLOGOUS:

- The arm of a human and the arm of a chimpanzee have similar functions and bone structures.

- Frogs and salamanders are both amphibians, and they also both have three-chambered hearts.

Explanation: I got this correct on the test, and so will you! Hope this helps!

Answer 2

1) The limbs of a bat and the forelimbs of a bird is an example of Analogous structures

2) The arm of a human and the arm of chimpazee is an example of Homologous structures

3) Frogs and salamanders is an example of Homologous structures

Homologous structures, are organs or systems of different living beings that have a common origin, but different adaptations. For example, the extremities of a dog and a dolphin, are homologous, have similar bones, only that some adapted to the race and others to swimming. On the other hand, analogous structures are organs or systems of different living beings that do not have a close origin in common, but are adapted to the same environment, for example, fins of fish and dolphin fins, the function is the same, the origin is different; or the wings of birds and the wings of insects.
