Answer:d
Explanation: I'm smart lol trust me
I believe the answer is b. decomposition adds to the soils nutrients, therefore creating the environment of plant growth which gives off o2.
The saline distributes rapidly (within about 15 minutes) from the intravascular to the interstitial compartment. And there, it is stuck.
The cells have active pumps and the membrane is impermeable to sodium; similarly, chloride is trapped.
Because normal saline is isoosmotic with the extracellular fluid, water does not have any osmotic pressure to shift between compartments, and it distributes itself according to the proportional distribution of sodium (i.e. about 25% of it stays intravascular and 75% enters the interstitial fluid).
(This may not be entirely accurate. Because the osmolality of the extracellular fluid increases, some water undegoes a shift into the extracellular compartment. The new equilibrium point is 290.2 mOsm/L. To achieve this, a whole 25ml of water has to move up into the extracellular compartment. So, the intravascular volume increases not by 250ml, but by... 256ml. What a big difference that makes. In order to remain detached from pedantic hair-splitting, I have opted to omit this from all the further calculations.)
Plasma osmolality doesn't change much, because it has received a load of essentially isoosmolar fluid.
<span>You will notice that the osmolality of the compartments increases by 0.2 mmol/L from your maths; but the osmoreceptors dont care.</span>

Answer:
In the gums
Explanation:
Lidocaine is a compound which can be used as a local anaesthetic. This anaesthesia works by blocking the voltage-gated channels which allows the influx of the sodium ions. As the sodium ions do not enter therefore an action potential is not generated in the axons as a result of which no pain is felt in the area.
In the given since the lidocaine is used by the dentist therefore the dentist in order to treat some dental problem must inject the lidocaine in the gums where the sensory receptors of the teeth are present.
Thus, in the gums is the correct answer.
