<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.
Answer:
interests center around the physics and chemistry of the terrestrial planets, in particular, as it relates to their origin and early evolution.
Explanation:
The balanced equation :
LiI(aq) + AgNO₃(aq) --> AgI(s) + LiNO₃(aq)
<h3>Further explanation</h3>
Given
Word equation
Required
Balanced equation
Solution
There are 3 ways to express a chemical equation:
- word equation
- skeleton equation
- balanced equation
Skeleton equation for reaction above :
LiI(aq) + AgNO₃(aq) ⇒ AgI(s) + LiNO₃(aq)
If we look at this reaction, all the cations and anions have a charge of 1 (+1 or -1) so the balanced reaction between the skeleton equation and the balanced equation is the same
The basic unit of mass in the metric system is grams
