Andru [333]

The brain is an organ composed of neurons which controls all the voluntary and involuntary of animals.  In humans, the brain is located in the skull where the brain is suspended in a fluid called cerebrospinal fluid.

As humans ages and becomes old aged, the neurons in the brain losing their ability to perform their function, if they are lost they cannot be regenerated.

Which statement is true about the layers of the Earth? * 1 as temperature and pressure increases, density increases 2 As tempera
nignag [31]

Answer:

1. As temperature and pressure increases, density increases

Explanation:

The earth is composed of three main layers: Crust, Mantle and Core. The density or mass per unit volume of the earth's layers increases as one moves from the surface towards the interior of the earth known as the core. Also, there is an increase in pressure and temperature as depth increases. There are three main sources of heat in the earth's core: (1) conserved heat from when the planet formed and coalesced, (2) heat due to friction caused by denser core material sinking to the center of the planet, and (3) heat from the decay of radioactive elements.

The earth's core is composed almost entirely of the metals, iron and nickel. The core has an inner solid layer and a molten outer core. Iron and nickel are both very dense metals, so the core of the earth is very dense and the density increases with depth with the inner core being the most dense layer of the earth.
