Since IDK which two you would choose, I'll just list all of them: fish have developed a light, streamlined body to get through water quickly to evade predators with and swim with ease, owls have big eyes so their pupils can get enough light to see in the dark since they're nocturnal, their light bodies and special (Fluffy???) flight feathers let it fly with virtually no sound, allowing it to sneak up on prey, tortoises have a large, hard shell for protection from predators and provides a mobile home on their back! Bats may be practically blind but that doesn't stop them when using echolocation to detect prey and chase it no matter what moves they make or obstacles in the way, snowshoe hares have big feet to sit on top of the snow in the cold winters where they live, their fur also changes colors as the snow melts and the plants start coming back in the more warmer seasons, poison dart frogs, sorry, IDK, cacti have developed spines all over them as self defense, (from what IDK) and they can last a long time without water (I think, don't quote me on that ^^') hope this helps

Damm [24]

The parts of the brain of a living organism which perform each of the functions are listed as follows:

Hypothalamus: it regulates sleep.

Optic nerve: it connects brain and eyes.

Cerebellum: it controls balance.

The frontal lobe: it controls thinking.

The brain stem: it controls breathing and heart rate.

The nucleus accumbens: it is the pleasure center.

<h3>What is a brain?</h3>

A brain can be defined as an organ of soft-nerve tissue that is found within the skull of vertebrates, and it's mainly responsible for the coordination of nervous activities, sensation and intellect in living organisms.

Based on scientific records and information, the two (2) sides of the brain (symmetrical left and right hemispheres) are able to communicate through the corpus callosum.

In conclusion, we can infer and logically deduce that the parts of the brain of a living organism which perform each of the functions are listed as follows:

Hypothalamus: it regulates sleep.

Optic nerve: it connects brain and eyes.

Cerebellum: it controls balance.

The frontal lobe: it controls thinking.

The brain stem: it controls breathing and heart rate.

The nucleus accumbens: it is the pleasure center.
