. Explain why some desert animals excrete uric acid rather than ammonia.(2 marks)​

Chemistry
1 answer:
avanturin [10]3 years ago
5 0

Answer:

AFAIK

Explanation:

uric acid is much less toxic than ammonia, hence bigger concentrations of it are tolerated in the body. This means you can excrete it while excreting very little water - beneficial wherever water's not abundant.

There's a tradeoff though, uric acid requires more energy to synthesize than ammonia, so pretty much all fish, say, excrete ammonia rather than uric acid - it's no problem to dilute ammonia since there's no water shortage.

You only have 15g of sodium to use for this reaction. how much copper(ii must you combine with the sodium to isolate the maximum
Eva8 [605]
The balanced chemical reaction is:

<span>CuCl2 + 2Na → 2NaCl + Cu 

We are given the amount of sodium to be used up in the reaction. This will be the starting point for our calculations.

15 g Na ( 1 mol / 22.99 ) ( 1 mol Cul2 / 2 mol Na ) (134.45 g / 1 mol ) = 43.86 g CuCl2 needed to be able to obtain the maximum amount of copper.</span>

What type of chest tube system does this statement describe?
Komok [63]

Answer:

<em>Dry suction chest tube system</em>

Explanation:

<em>The dry suction drains that are self-regulating today use a small, adjustable regulator installed into the drain. </em>

So long as there is enough air flow from the suction of the wall (that will be shown on the drain) it will respond correctly to changes in the pressure of the source or the patient to retain suction at the drain level.

It's also a quiet mode of activity.
