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

Answers;
The limbs of a bat and the forelimbs of a bird have similar functions but different anatomy -homologous structures
The wings of a bird have a skeletal structure, but the wings of bees do not-  analogous structures
The arm of a human and the arm of a chimpanzee have similar functions and bone structures- Homologous structures
Frogs and salamanders are both amphibians, and they also both have three-chambered hearts- Analogous structures.

Explanation; 
Analogous structures have a different evolutionary ancestries but they have the same function; while homologous structures are the opposite; they have similar ancestries and common traits but maybe not have the same function in an organism.

Nucleus is the organelle that contains chromosomes

Ibelieve the answer is a-broad because that is a leafed plant.
