Question

Flipper of Whale is the modification of
A. Skin
B. Hind limb
C. Forelimb
D. Patagia

Answer 1

Creatures with flippers incorporate penguins (whose flippers are additionally called wings), cetaceans (for example dolphins and whales), pinnipeds (for example walruses, earless and eared seals), sirenians (for example manatees and dugongs), and marine reptiles, for example, the ocean turtles and the now-terminated plesiosaurs, mosasaurs, ichthyosaurs, and metriorhynchus.

Complete step by step answer: A flipper is a normal level forelimb developed for development through the water. Flippers give lift, so they can ascend in the water and control their degree of sea-going profundity. A flipper is a wide, leveled appendage adjusted for development through the water. It alludes to the completely webbed, swimming members of amphibian vertebrates that are not fish. The flippers are constrained by solid pectoral muscles and can shift in size with every species. In creatures with two flippers, for example, whales, the flipper alludes exclusively to the forelimbs. In creatures with four flippers, for example, pinnipeds and ocean turtles, one may separate front and rear flippers, or pectoral flippers and pelvic flippers
Hence, the right answer is option C.

Note: Marine warm-blooded creatures have advanced a few times, creating comparable flippers. The forelimbs of cetaceans, pinnipeds, and sirenians present an exemplary case of focalized
advancement. There is boundless intermingling at the quality level. Distinct replacements in like manner qualities made different oceanic transformations, a large portion of which comprise equal development in light of the fact that the replacements being referred to are not exceptional to those creatures.
