Answer:
Water serves to suspend the red blood cells to carry oxygen to the cells. It is the solvent for the electrolytes and nutrients needed by the cells, and also the solvent to carry waste material away from the cells. With water as the solvent, osmotic pressure acts to transport the needed water into cells.

Answer:
[F⁻]² = 0.068 M
Explanation:
ZnF₂(s) ⇌ Zn²⁺(aq) + 2F⁻(aq)
At equilibrium the Kps can be calculated by the following equation:
Kps = [Zn²⁺][F⁻]²
Therefore, the concentration of F⁻¹ can be calculated:
[F⁻]² = Kps/ [Zn²⁺]
[F⁻]² = = 3.0 x 10⁻² / 4.4 x 10⁻¹M
[F⁻]² = 0.068 M
Answer:
True

This are acts or actions that concur with situational expectations.
Planck's constant =
6.62607004 × 10-34 m2 kg / s
Explanation:
Step by Step explanation
The Planck constant, or Planck's constant, is a fundamental physical constant denoted h, and is of fundamental importance in quantum mechanics. A photon's energy is equal to its frequency multiplied by the Planck constant. Due to mass–energy equivalence, the Planck constant also relates mass to frequency. Wikipedia
The statement is false. We know this beause this principle states that impossible for two electrons to have the same four electronic quantums. Remember that the orbtials can each have only two electrons max.
