Sharks and whales look similar, but they’re different types of animals. whales are mammals, while sharks are fish. which body part do sharks have that whales lack? need it asap

Gills

Explanation:

Sharks are fishes and thus have gills through which they absorb oxygen from the water.

On the other hand,  Whales being mammals use lungs to breathe. They can’t directly obtain oxygen from water.

Gills

Explanation:

This is because Whales have evolved differently to where they cant breath under water but they can last hours under water as water builds up in their blowhole and when they come up to breath they blow it out so they can go back under and store more  

explanation:

the transfer for conduction is the heat transfering from the liquid to the spoon

the transfer for convection is the heat rising from the liquid to the air

the transfer for radiation is the heat going through the sides of the cup and to the air

at least that is what i would do
