Ket [755]

Answer:

But without plate tectonics, Earth will simply stop making new ones. The mountains we have now would erode over a few million years, turning into low, rolling hills. Our planet would eventually flatten out, with more land ending up underwater. On the bright side, there'd be fewer natural disasters.

The graphs above show Maxwell-Boltzmann distributions for one-mole samples of Ar(g). Graph 1 shows the distribution of particle
Aleks [24]

The Maxwell-Boltzmann distributions is a description of the speeds of different gases at the same temperature.

<h3>What is Maxwell-Boltzmann distributions?</h3>

The Maxwell-Boltzmann distributions is a description of the speeds of different gases at the same temperature. Recall that at the same temperature, the relative speed of gas molecules is described by the  Maxwell-Boltzmann distributions.

The question is incomplete hence we can not be able to show the exact relationship between the two graphs in order to arrive at a justification for the student's claim.

Which three of the following statements accurately describe the blood buffering system in humans? The blood buffering system...
ikadub [295]

Answer:

b) maintains the pH of blood near 7.4.

c) regulates the blood pH at 7.4 +/- one pH unit.

f) is facilitated by the enzyme carbonic anhydrase, which interconverts carbon dioxide and water to carbonic acid (ionizes into bicarbonate and H^+).

Explanation:

The pH of human blood is slightly acidic i. e. 7.4. The enzyme carbonic anhydrase is responsible for the regulation to neutral and prevent it from acidic. the enzyme carbonic anhydrase helps in the conversion of carbon dioxide to carbonic acid and bicarbonate ions. When the blood reach to lungs, the bicarbonate ions convert back to CO2 and this carbondioxide is exhaled from the body.
