Between a cation, which is usually a metal, and an anion, which is usually a nonmetal. A covalent bond involves a pair of electrons being shared between atoms.
Answer: hypothesized that the higher pH levels would increase the rate
of movement of the Artemia. The students placed the Artemia in petri dishes with 2 mm x 2
mm grids marked off on the bottom of the dishes. The students calculated how fast the Artemia
traveled in each pH (4-9) solution by counting the number of squares on the grid that the
Artemia crossed per second of timing.
The data collected from their experiment is presented below:

Explanation:
The nervous system comprises the central nervous system, consisting of the brain and spinal cord, and the peripheral nervous system, consisting of the cranial, spinal, and peripheral nerves, together with their motor and sensory endings.
Inner Core.The Crust, oxygen, silicon, aluminum, iron, calcium, magnesium, potassium and sodium<span>. It is divided into huge plates that float on the mantle, which is in the next layer. its about 25 miles thick, and there is really not a average temp.

The Mantle, is a silicate rocky shell about 1,802 miles thick.
Outer Core, <span>composed of mostly iron and nickel that lies above Earth's solid
