Answer:
Whales and dolphins are mammals and have lungs instead of gills for breathing. They have blowholes at the tops of their heads that function like nostrils; they need to put their heads above water every so often to breathe. Both dolphins and whales have hair instead of scales, another quality that is specific to mammals. The animals have live births instead of laying eggs, and baby dolphins and whales nurse from their mothers. Whale and dolphin births take place near the surface of the water, so the young animals can easily take their first breath.
Both whales and dolphins rely on the sounds they make for survival, even though the sounds are utilized differently by each animal. For instance, whales make high-pitched groans and whistles to communicate with one another to warn against danger or navigate during migration
Answer:
COMPARISON AND CONTRAST OF WHALES AND DOLPHINS
Both dolphins and whales belong to the cetacean family and are marine animals that reside in the ocean. Some scientists even assert that dolphins are a type of whale, as the two animals have a number of shared characteristics. However, there are distinct differences between whales and dolphins as well that will teach you more about the physical appearance of these marine creatures and how they survive in their environment.

WHY ARE THE TROPHIC LEVELS AND ENERGY REPRESENTED IN THE FORM OF PYRAMIDS?
Answer:
An energy pyramid shows the distribution of energy among trophic levels. Producers use energy from sunlight to make food. Herbivores eat plants—the producers—to get energy. ... Each level above gets smaller, because as energy is lost as heat, there is less energy avail- able as food for organisms.
Most fresh water fish are hypertonic, meaning their body cells contain more salt than the surrounding water. Since osmosis should push water into their cells, why don't they explode? They don'Ât drink any water because they get so much from osmosis. They have adapted to live with high osmotic pressure. They urinate a lot, so the water does not build up. Their cells have adapted to absorb salt. All of the above
Answer:
They urinate a lot, so the water does not build up.
Explanation:
Freshwater fishes are fishes that live in freshwater habitat i.e. little or no salt. This means that the fishes are hypertonic (have more salt) to their external environment. Due to their hypertonicity, freshwater fishes tend to take in more water via osmosis.
Freshwater fishes, however, do not explode despite this phenomenon because they pass out the excess water via urine waste. Freshwater fishes urinate a lot, hence, the absorbed water does not build up in their bodies.
