Answer:
The correct answer is "obligatory water reabsorption in the proximal convoluted tubule".
Explanation:
The mechanism for producing concentrated urine cannot include the obligatory reabsorption of water in the proximal convoluted tubule since this process is part of the nephron, the system that filters the blood. Glucose and amino acids are reabsorbed almost entirely, as are approximately 70% of filtered potassium and 80% of bicarbonate.
Have a nice day!
Answer:
Decreasing surface area of the solid in the liquid.
Explanation:
I don't know how to explain this without using. an example. So, here it is: If you were dipping bread in water, the bread would be completely soaked if you dipped the whole thing, but if you only allowed one part of the bread to be in the water, it would take longer for the water to soak all the way into it. The amount of surface area that is allowed to touch what is making the solid dissolve determines how quickly the whole thing will be dissolved.
Answer:
Cooling
Explanation:
Now, what we know is that the reaction would be exothermic. This knowledge is extractable in two ways. We know quite well that heat is released to the environment or surroundings and also the value of the enthalpy is negative. Thus we conclude that the reaction is exothermic.
Now, since heat is released to the environment, there is the need for an apparatus that would cool down the increased surrounding temperature. Hence, we can conclude that what we need actually is to provide cooling for the reaction mixture
