As they are mostly characterized for there small size and very complicated form of morphology, while the insects are found to be living inside the soil and on the plant structures.

Explanation:

Insects are the one who plays the pivotal role in the decomposition of the living beings i.e both plants and animals inside a specific region.

Answer:

Prezygotic barriers:

1. Habitat isolation

2. Behavioral isolation

Explanation:

Pre-zygotic barriers are the barriers which do not allow the formation of the zygote in the organisms.

The two mechanisms of the pre-zygotic barriers are the:

1. Habitat isolation: the Flycatchers do not share the same habitat which is also mentioned in the question that they live on different islands.

2. The behavioural isolation: the Flycatchers could have evolved the different mating rituals as a result of which the could not interbreed.

Thus, Habitat isolation and Behavioral isolation are correct.

The brain stem consists of the ________. The brain stem consists of the ________. cerebrum, pons, midbrain, and medulla midbrain

skelet666 [1.2K]

Answer:

midbrain, medulla, and pons

Explanation:

The brainstem (also known as truncus encephali) is localized in the posterior part of the brain, in the base between cerebral hemispheres and the cervical cord. It's divided into three parts, the midbrain or mesencephalon, the pons or mesencephalon, and the medulla oblongata also known as long medulla or myelencephalon. In the image I added you can see the brainstem structure.

Some of the brainstem functions include the regulation of respiratory and cardiac function, thermoregulation, and other functions related to vision, sleep, etc.

I hope you find this information useful and interesting! Good luck!
