Which one of the following pairs of animals are similar to each other ...
Answer:
Similarity between animal pairs based on features:
a) Pteropus and Ornithorhyncus - viviparity
Both Pteropus (fruit bats) and Ornithorhyncus (platypus) are mammals that exhibit viviparity, which means giving birth to live young ones instead of laying eggs.
b) Garden lizard and crocodile - three chambered heart
Both Garden lizard and crocodile have a three-chambered heart, which consists of two atria and one ventricle. This type of heart is less efficient than a four-chambered heart found in mammals and birds, as it causes mixing of oxygenated and deoxygenated blood.
c) Ascaris and Ancylostoma - metameric segmentation
Both Ascaris (roundworm) and Ancylostoma (hookworm) exhibit metameric segmentation, which means their body is divided into repeating segments that have similar structures and functions.
d) Sea horse and flying fish - cold-blooded (poikilothermal)
Both Sea horse and flying fish are cold-blooded (poikilothermal) animals, which means their body temperature fluctuates with the surrounding environment. They cannot regulate their body temperature internally like warm-blooded (homeothermic) animals such as mammals and birds.
Conclusion:
In summary, the pairs of animals that are similar to each other for the feature stated against them are Pteropus and Ornithorhyncus for viviparity, Garden lizard and crocodile for a three-chambered heart, Ascaris and Ancylostoma for metameric segmentation, and Sea horse and flying fish for being cold-blooded (poikilothermal).
Which one of the following pairs of animals are similar to each other ...
Sea horse and flying fish are fishes and fishes are cold-blooded animals i.e. the temperature of their body varies with the environment. Ornithorhyncus is oviparous, crocodiie has 4-chambered heart, Ascaris and Ancylostoma do not show metameric segmentation.
