Stars begin to form from clouds of gas in space. The cold temperatures and high densities (compared to elsewhere in space, but would be considered a vacuum on Earth) of these clouds allow gravity to overcome thermal pressure and start the gravitational collapse that will form a star.
There is a
transient electro-physiologic dysfunction of the reticular activating system in
the upper midbrain caused by rotation of the cerebral hemispheres on the fixed
brainstem. -The CSF cushions the brain from light trauma in times of more
severe impact, the forces on the brain may be linear, angular, or rotational, in
rotational movement, the head turns around its center of gravity: this is the
primary mechanism causing concussion.

Explanation:
4. Gene frequencies will remain constant
It is probably the l<span>amellae.
The lamellae are sheets of bony matrix. This bony matrix is produced by o</span>steoblasts, which are cells that synthesise collagen<span> and specialised proteins like </span>osteocalcin<span> and </span>osteopontin. These are then the most important constituents of the bony matrix.
