Answer:
Keystone species
Explanation:
A keystone species is the one that affects the structure and function of the community irrespective of its small population size. The keystone species is not the most abundant species of the community but occupies an ecological niche that regulates and maintains the structure and function of the rest of the community.
Elephants serve in the dispersal of seeds, make new habitats for various plant species by crushing the woody plants with their feet. Since elephants are shown to regulate the species richness by making space for new species and seed dispersal, they are the keystone species.
Answer:
The best example of this is ‘Pavlov’s dog’; classical conditioning is sometimes referred to as Pavlovian conditioning.
A honey bee's proboscis extension reflex - the bee extends its proboscis as a reflex to antennal stimulation.
Answer:
Since Skull is the most complete fossil, the features of the skull that reflects Humans as bipedal omnivores are: The teeth and the foramen magnum.
Explanation:
Humans are bipedal because they can move with their two legs, and they are omnivores because of their ability to eat both meat and plants.

<h2>The equator is the longest latitude at 0°.</h2><h2>The equator isn't influenced any change when the earth revolves around the sun cause winter and summer. </h2><h2>That's why equator is warmer than north and south pole.</h2>
<h2>I hope you understood</h2>
Answer: Irreducible complexity
Explanation:
Irreducible complexity can be defined as characteristic of complex system it is impossible to reduce the complexity of the system by removal of any parts to maintain the functionality of the system. The given situation is an example of irreducible complexity. The increased levels of tryptophan will inactivate the synthesis process but it is again reactivated when the levels decreases this is suggestive of the fact that it is impossible to reduce the complexity of the system.
