Homologous or not ?

What is the difference between a homologous structures and analogous structures? Please also give an example.

fish have scales while cats have fur. Structural characteristics of organisms make up their morphology, which includes both external features such as shape and color as well as internal features such as bones and muscles.

analogous structures are parts of an organism that are different but preform the same task. like a bees wings and a birds wings.
homologous structures are parts of an organism that have a similar structure but preform different tasks. like a fish's fin and a mouses leg.

The difference between the two are that homologous structures and analogous structures are that analogous structure are ment for the same thing but look different and homologous structures have the same bones but get used differnetly.

Nicole said...

the differents is that homologous are from a common ancestor and analogous are not from a common ancestor.

Homologous structures are the same and Analogous structures are different. A example for a Homologous structure would be a bat and a mouse because they both have four limbs. an example for a Analogous structure would be a penguin and a bee because they are not alike.

The differences between homologous structures and analogous structures are, homologous structures have similar structures, they have a different function, and they come from a common ancestor. Analogous structures have different structures, similar functions, and they are not from a common ancestor. An example of a homologous structure is a human arm and the wing of a bird and an example of an analogous structure is wings in a bat and fins in penguins.

Homologous are similar structures in different structures ad species and Analogous are the same are diffrent structure with the diffrent functor

Homologous- Have the same structures

Analogus- Have different structures same functions.

Homologous means they are the same structure, but different species. Analogous, however, is a different structure that has the same function. For example, a bee's wing and a robin's wing are both used to fly, but they are different structures.

The difference between homologous and analogous is homologous is the same structure, but different function and analogous is a different structure, but similar functions.

Homologous Structures are simular Analogous Structures are different.

Homologous is te same structure, but a different function and analogous different structures.

same thing but difrint abilty


difrint b ut same abilty

Homologous is sorta maybe kinda the same and analogous are different structures.

homologous structures have similar structures
analogous structures have different structures

Homolgous structures are structures that are similiar in related organisms because they were inherited from a common ancestor. Therefore, analagous structures are structures that are similiar in unrelated organisms. This is how they differ. An example of a homolgous structure is the wing of a bat, and an example of an analogous structure is the fin on a penguin.

Homologous structures are derived from a common ancestor, but have differing functions. For example, the fin of a whale and the arm of a human. They have the same structure but have different purposes. Analogous structures are not derived from the same ancestor, but have a similar purpose. For example, the wing of a flying insect, and a parrots wing.

Homologous: similar structures , different functions
Analogous: similar functions, different structures.

The difference between homologous and analogous is homologous has the same structure and different uses as analogous is the same uses but different structures.

Allie said...

The difference between homologous and analogous structures are homologous structures have the same structures but use them for different things and analogous structures look different but are used for the same reason. An example of a homologous structure is a whale fin and a mouse paw. An example of an analogous structure is a birds wings and an insects wings.

The difference between homologous and analogous is homologous is same functions and same type of structure like a human forearm and a porpoise fin and analogous is same functions but different type of structure like a duck and a fly.
