Which among the following is incorrect about Gnathostomata?a)These are...
Incorrect Statement: This super class is classified into Pisces and tetrapods based on their type of blood (Option B)
Explanation:
- The super class Gnathostomata includes all vertebrates with jaws. This group is characterized by the presence of hinged jaws, which allow them to effectively capture and process food.
- Gnathostomata is divided into two major groups: Pisces (fish) and tetrapods (four-limbed vertebrates).
- The classification of Pisces and tetrapods is not based on their type of blood, but rather on their anatomical features and evolutionary history.
- The Pisces group includes all fish, which have gills for respiration and fins for locomotion. Fishes are cold-blooded, meaning their body temperature is determined by the temperature of their environment.
- Tetrapods, on the other hand, are characterized by having four limbs or descended from four-limbed ancestors. This group includes amphibians, reptiles, birds, and mammals. Tetrapods are warm-blooded, meaning they can regulate their own body temperature.
- The use of fins for movement is a characteristic of fish (Pisces). Fins are specialized appendages that fish use for propulsion and maneuverability in water.
- Tetrapods, on the other hand, have limbs that they use for movement on land. Limbs are adapted for various forms of locomotion, such as walking, running, jumping, flying, or swimming in some aquatic tetrapods.
- Therefore, the incorrect statement is option B, which suggests that the classification of Gnathostomata is based on the type of blood. In reality, the classification is based on anatomical features and evolutionary relationships.
Which among the following is incorrect about Gnathostomata?a)These are...
Gnathostomata are vertebrates with jaws. This super class is classified into psices and tetrapods based on the organs they use for their movement. Pisces use fins for their movement. Tetrapods use limbs for their movement.
