Most metamorphic processes take place B. a few kilometers below Earth’s surface.

Metamorphism is the change of minerals or geologic texture in pre-existing rocks without the protolith melting into liquid magma. Metamorphism often occurs on two scales: contact and regional. Contact metamorphism occurs locally in areas adjacent to igneous intrusions or in areas that are in contact with hot water known as hydrothermal fluids. Whereas regional metamorphism occurs over much larger areas such as rising mountain ranges, large igneous intrusions can form and warp overlying strata increasing the pressures above the intrusion. Regional metamorphism usually produces foliated rocks such as gneiss and schist.
There are other ways that metamorphic rocks can form, Dynamic metamorphism. Dynamic Metamorphism also occurs because of mountain-building. The huge forces of heat and pressure cause the rocks to be bent, folded, crushed, flattened, and sheared.
Metamorphic rocks form when increased heat and pressure force physical changes in the crystalline structure of an existing rock. Under the right conditions, any type of rock can become a metamorphic rock including igneous rocks, sedimentary rocks, and even other metamorphic rocks. Therefore metamorphic processes result due to intense heat and high pressure below the Earth's surface.

I can answer the first one, being options 2 and 5. The second question I am not sure about. I would think option 1, since there are less species and organisms on the island, so there might be less biodiversity.
Answer:
1. Medulla
2. Heart rate and breathing
Explanation:
The brainstem is the part of the brain that was formed earlier in the history of the evolution of the brain, therefore, is present in the posterior region of the brain. The brainstem is composed of three parts called the pons, the midbrain and the medulla.
The medulla is the portion which is connected to the spinal cord and thus the transfers the signals form the spinal cord to the brain structures.
The brainstem controls the main functions of the body like the breathing rate, the heart rate, consciousness, blood pressure and many involuntary functions.
Thus, Medulla and Heart rate and breathing are correct.
