A result of convergent evolution are the webbed feet of ducks and frogs.
Explanation:
The evolution of the animals, or rather the development of adaptive features, works in very interesting manner. It is very common in nature that animals that are closely related do not share similar characteristics, or the opposite, animals that are not closely related but share similar characteristics. The later case, is referred to as convergent evolution, where totally different animals have developed the same or very similar characteristics in order to be better suited for their environment.
In this case we have the ducks and frogs, and the webbed feet as shared adaptations, or feature. The ducks are birds, while the frogs are amphibians, and their last common ancestor has lived hundreds of millions of years ago. Despite that, both animals have developed webbed feet, and the reason for this has been that both animals have faced the same challenge, swimming and diving, and the webbed feet help them to be much faster and more agile in the water.
Other examples of convergent evolution (in the present and in the past) are:
- Hyena - Tasmanian devil
- Sandy cat - Fenec fox
- Smilodon - Thylacosmilus
- Bats - Birds

The answer to this question would be: parasympathetic division
Parasympathetic nervous is part of the autonomous nervous system. In the autonomous nervous system, the sympathetic system is used when you enter the "fight or flight" mode. In this case, the body will be prepared to be able to take a decision as quickly as possible in a strenuous state. The nervous also cause an increase in the heart and breathing rate to increase body capability.
Parasympathetic is the opposite of it which was activated to calm the body so it can maintain the normal body function.
The two animals which use echolocation are bats and dolphins.
Both hunt their prey by articulating high-pitched sounds and listening for the echoes.
<h3>What is echolocation?</h3>
Echolocation is a method used by bats, dolphins and other animals to select the location of objects using reflected sound. This allows the animals to move around in pitch darkness, so they can guide, hunt, identify friends and enemies, and avoid obstacles.
Thus, bats and dolphins are two animals that use echolocation.

Answer:
the correct answer is enzymes
Explanation:
enzyme act as catalyst and is a biological molecule which within the cell membrane can speed up or increase the rate of biological reaction without affecting itself and is obtained unchanged at the end of reaction
