D iron does not conduct electricity

Answers

Answer 1
Answer:

Answer:

Scientists don't think the Earth's core contains iron, they know it is mostly made of iron.

Explanation:

Geologists study internal rumbles caused by earthquakes which send rippling seismic waves through the whole Earth. Seismic waves bent as they pass through different layers because their density varies, since they are made of different materials. Geologists have calculated the density of iron and they can infer that the inner and outer core as almost entirely made of iron. What they do not agree upon 100% is about the outer core being melted iron or solid iron.

Answer 2
Answer: the best answer seems to be B. iron is a heavy element and would sink into the planet because iron is a metal so it is heavy and when something is heavy it sinks the lowest it can go, so when the earth was developing, iron and other heavier substance sunk towards the middle of earth

What is the Brainstem?

The brainstem is positioned beneath the forebrain and midbrain within the central nervous system. It is a vital component connecting the brain to the spinal cord and plays a crucial role in controlling essential bodily functions such as breathing, heart rate, digestion, and consciousness.

Comprising three main structures – the medulla oblongata, pons, and midbrain – the brainstem acts as a conduit for information flow between the brain and the rest of the body. Its strategic location highlights its significance in regulating involuntary physiological processes necessary for overall functioning and survival.
