What is the mechanism by which a buffering system maintains a certain ph when exposed to acids and bases?
Ostrovityanka [42]
<h2>Buffering System of Acids And Bases</h2>

Explanation:

  • The <em>bicarbonate buffering framework </em>keeps up ideal pH levels and directs the <em>carbon dioxide fixation</em> that, moves any corrosive base unevenness.
  • Renal physiology controls pH levels through a few incredible instruments that discharge abundance acid  or base.  
  • Blood contains a lot of <em>carbonic corrosive, a feeble corrosive, and bicarbonate,a base.  </em>
  • They help keep up the bloods pH at 7.4. On the off chance that blood <em>pH falls beneath 6.8 or transcends 7.8, </em>one can get wiped out or pass on.
  • The <em>bicarbonate kills </em>abundance acids in the blood while the <em>carbonic corrosive kills overabundance bases.  </em>
  • A cushion is a concoction framework that forestalls an extreme change in liquid pH by hosing the adjustment in hydrogen particle focuses on account of overabundance corrosive or base.

skad [1K]

Explanation:

It should be in this order from oldest to youngest: 2,1,5,7,9,3,4,8,6.

Since we know 2 is the oldest and once each organism goes extinct it stops being in any samples, we can start at 2 and go through the samples to see where that fossil shows up again and when we find the next sample its in, we pay attention to any new fossils that show up and move onto the next sample with the second fossil in it and so on.
