What are homologous structures give 2 examples?

What are homologous structures give 2 examples?

Homologous structures share a similar embryonic origin; analogous organs have a similar function. For example, the bones in the front flipper of a whale are homologous to the bones in the human arm. These structures are not analogous. The wings of a butterfly and the wings of a bird are analogous but not homologous.

Are tails homologous structures?

Monkeys, cats, rats and other mammals have tails. In mammals, the tail is an extension of the torso, made of flexible vertebrae. Due to this link, the mammalian tail and the human coccyx are homologous structures.

Are bat wings and whale flipper homologous?

Encyclopædia Britannica, Inc. When two or more organs or structures are basically similar to each other in construction but are modified to perform different functions, they are said to be serially homologous. An example of this is a bat’s wing and a whale’s flipper. An example of this is the wings of bats and birds.

Is human arm and whale flipper homologous?

An example of homologous structures are the limbs of humans, cats, whales, and bats. Regardless of whether it is an arm, leg, flipper or wing, these structures are built upon the same bone structure. Homologies are the result of divergent evolution.

Is a dolphin Flipper a homologous structure?

A dolphin’s flipper, a bird’s wing, a cat’s leg, and a human arm are considered homologous structures. Bats, whales, and many other animals have very similar homologous structures, demonstrating that these creatures all had a common ancestor.

Is human arm and alligator homologous?

For example, a human arm and alligator forelimb both are having the same homologous structures. The human arm classified into the upper arm and forearm. The forearm contains two bones, one is Radius and the second one is Ulna. Alligator forelimb classified into Radius, Ulna, and humerus.

Is a Dolphin analogous or homologous?

Another example of analogous structures are dolphins and sharks as whole species. Although we might think of dolphins and sharks as being relatively similar, their morphology says otherwise. Dolphins are mammals that have live births and have fins with a homologous structure to human arms.

Is body shape homologous or analogous?

Sharks’ and dolphins’ similarities (body shape, fin, and flippers) are analogies — traits that each lineage evolved independently.

Are shark and whale tails homologous?

Homologous or Analogous? Their tail fins are homologous, meaning their similarity is due to inheritance from a common ancestor. On the other hand, the tail fins of orcas and sharks are not homologous, because the common ancestor of all mammals did not have tail fins.

What are fins homologous to?

The paired fins in fish and limbs in tetrapods are a good example of homologous organs. They were derived from locomotive organs in common ancestors of vertebrates, and they share many developmental processes and genetic networks.

What are the different types of fins?

• Fish Fins. Fins are one of the most distinctive features of a fish and appear in several different forms.
• Dorsal Fins.
• Tail Fin or Caudal fin.
• Ventral or Pelvic Fins.
• Anal Fin.
• Pectoral Fin.
• Finlets or Scutes.

Which is dorsal fin?

A dorsal fin is a fin located on the back of most marine and freshwater vertebrates within various taxa of the animal kingdom. Most species have only one dorsal fin, but some have two or three.

Where are fins used?

Fins are most commonly used in heat exchanging devices such as radiators in cars, computer CPU heatsinks, and heat exchangers in power plants. They are also used in newer technology such as hydrogen fuel cells.

What is the function of fins in fish?

Fins are appendages used by the fish to maintain its position, move, steer and stop. They are either single fins along the centerline of the fish, such as the dorsal (back) fins, caudal (tail) fin and anal fin, or paired fins, which include the pectoral (chest) and pelvic (hip) fins.

Why are fins used?

Fins are thus used whenever the available surface area is found insufficient to transfer required quantity of heat with available temperature gradient and heat transfer coefficient. In the case of fins the direction of heat transfer by convection is perpendicular to the direction of conduction heat flow.

How do fins work?

A fin is a thin component or appendage attached to a larger body or structure. Fins typically function as foils that produce lift or thrust, or provide the ability to steer or stabilize motion while traveling in water, air, or other fluids. Fish fins are used to generate thrust and control the subsequent motion.

What is infinitely long fin?

0.999. 5.0. 1.000. We observe from the table that heat transfer from a fin increases with mL almost linearly at first, but the curve reaches a plateau later and reaches a value for the infinitely long fin at about mL=5. Therefore, a fin whose length is L=m/5 can be considered to be an infinitely long fin.

What fin means?

Does FIN mean the end?

The Latin root word fin means an ‘end,’ as in a ‘boundary’ or ‘limit. ‘ Some common English vocabulary words that come from this Latin root word include final, finish, and definition.
