Answer the following questions:
1. How do humpback whales communicate?
2. Why do butterflies walk on the leaves?
3. Why does a snake flick its tongue?
Answers
Answer:
Ans1. Whales are very social creatures that travel in groups called “pods.” They use a variety of noises to communicate and socialize with each other. The three main types of sounds made by whales are clicks, whistles, and pulsed calls.
Clicks are believed to be for navigation and identifying physical surroundings. When the sound waves bounce off of an object, they return to the whale, allowing the whale to identify the shape of the object. Clicks can even help to differentiate between friendly creatures and predators.
Whistles and pulsed calls are used during social activities. Pulsed calls are more frequent and sound like squeaks, screams, and squawks to the human ear. Differing vocal “dialects” have been found to exist between different pods within the same whale population. This is most likely so that whales can differentiate between whales within their pods and strangers.
Ans2. Butterflies taste with their feet.
Their feet have taste sensors on them that help to locate food for their caterpillars. They stand on a leaf and give it a taste. If they determine the plant is something their caterpillars can eat, they'll lay their eggs in this spot.
Ans3. A snake may appear threatening when it flicks its tongue out, but it's simply trying to get a better sense of its surroundings by "tasting" the air.
To compensate for their poor eyesight and limited hearing , most snakes have an excellent sense of smell. Although snakes have nostrils, they also use their tongues to pick up the scent of nearby prey or predators.
When a snake flicks its tongue, it collects odors that are present in miniscule moisture particles floating through the air.
