Answer:
Look below plz :))
Explanation:
1.) In a chemical change, the molecules in the reactants interact to form new substances. In a physical change, like a state change or dissolving, no new substance is formed. Explain that another way to say that no atoms are created or destroyed in a chemical reaction is to say, “Mass is conserved.”
2.) Carbon Dioxide and Water Out: During combustion, the atoms in ethanol and oxygen are rearranged into carbon dioxide and water. The carbon dioxide and water leave the top of the flame.
Answer:
an epidemic of an infectious disease that has spread across a large region, for instance multiple continents or worldwide, affecting a substantial number of individuals.
Answer:
answer is part (C)
Explanation:
mRNA takes the DNA code to the ribosome so that the specific protein can be made that makes up a specific organ
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>
