An elevated ridge of cerebral tissue inward folds of cerebral tissue is called a GYRUS.
Gyrus are usually surrounded by sulci( depressions).
</span>They exist because it allows the human, and other mammalian brains, to have <span>a larger surface area. Since the brain is confined to the skull and the that space is limited
this will allow more cortical surface
area, and greater cognitive function to exist. </span>
<span>A heterogeneous mixture that has larger dispersed particles that settle over time is a suspension.</span>
Gases dissolving decreases the entropy of the system, so the equilibrium shifts towards the side with greater entropy when temperature increases causing the gasses to escape faster in warmer liquids.
