<h3>
Answer:</h3>
B) partial pressure of oxygen
<h3>
Explanation:</h3>
- All tissues and cells in the body require oxygen to carry our respiration for the provision of energy in the form of ATP.
- Oxygen is exchanged in the lungs and is loaded into hemoglobin, a pigment in the red blood cells that carries oxygen in the tissues. This occurs through simple diffusion that is facilitated by a concentration gradient.
- In the tissues, internal respiration takes place where oxygen is unloaded from hemoglobin and diffuses into nearby cells. Diffusion occurs as a result of the difference in the partial pressure of oxygen in the blood vessels and that in the blood tissues.
- The partial pressure of oxygen in the blood vessels is higher compared to partial pressure in the cells, thus, the oxygen gas will diffuse into the cells.
The hybridization will be sp3. I hope that is helpful.
Answer:
A Half Life
Explanation:
The half life is the time it takes for the substance to become reduced by half as a consequence of decay.
One molecule of water contains two atoms of hydrogen and one atom of oxygen, the atomicity of water is three.
A is marking the solvent molecules which is marked in blue. And B is marking the whole solution.
Option C
<h3><u>Explanation:</u></h3>
A solution is defined as the homogeneous mixture of a solute in a solvent in a range of concentration where generally solvent is more in amount than in solution.
A solute is the component of the solution which is generally less in amount and is homogenously mixed with the solution. Here they are marked in blue. And the molecules that are representing the solvent are marked in orange colour. The solute and the solvent total makes the solution which is marked by B.
