One of the buffers that contribute to pH stability in human blood is carbonic acid (H2CO3). Carbonic acid is a weak acid that, w

hen placed in an aqueous solution, dissociates into a bicarbonate ion (HCO3-) and a hydrogen ion (H+).
Thus, H2CO3 = HCO3- + H+
If the pH of the blood increases, one would expect:

(A) a decrease in the concentration of HCO3- and an increase in the concentration of H+

(B) an increase in the concentration of H2CO3 and a decrease in the concentration of HCO3-

(C) a decrease in the concentration of H2CO3 and an increase in the concentration of HCO3-

(D) an increase in the concentration of HCO3- and a decrease in the concentration of OH-

(E) a decrease in the concentration of HCO3- and an increase in the concentration of both H2CO3 and H+.

I'm not sure if it is C or D ​

Answer:

The answer is "Option C".

Explanation:

In the given question, the pH scale is used to evaluate acid or basic (alkalinity) formulas. It is nearly positive throughout the blood. Human blood has to maintain its pH at about 7.4, to prevent dramatically increased or lower changes, even though the bloodstream enters or exits acidic or essential substances.  

  • The buffers are essential for stabilization management. Calcium carbonate produced as carbon dioxide joins the blood system and combines with the liquid is a buffer which adds to the pH level in the human blood.
  • It is returned to the water and distributed as a waste product until it enters the lungs, that's why choice C is correct.

Answer:

<u><em>It is because humans have much larger genomes than bacteria</em></u>

<u><em /></u>

Explanation:

It is because humans have much larger genomes than bacteria. The largest bacterial genome ; human clocks. But corn is about 3 times that, spruce is twice again that and some plants go even bigger. For example, every one of tulip’s chromosomes is about one human genome in size, and bacteria are haploid, humans are diploid. That makes assembling the DNA fragments much more tricky, as you don’t want to have a final sequence that switches between the two haplotypes.

The central nervous system (CNS), which is made up of the brain and the spinal cord, and the peripheral nervous system (PNS), which is comprised of nerves and ganglia (small concentrations of grey matter).

The brain sends messages to the peripheral nerves in the body via the spinal cord, these have control of muscles and internal organs.
