  2. BThe Cas9 protein cuts DNA at random sites
  3. CA guide RNA pairs with the matching DNA sequence
  4. DIt reads the amino acid sequence of the protein
8.Hard

A patient breathes very slowly, so carbon dioxide builds up in the blood. What happens to the blood pH, and why?

  1. AIt rises, because CO₂ removes hydrogen ions
  2. BIt stays the same, because CO₂ does not dissolve in blood
  3. CIt falls, because CO₂ forms carbonic acid in the blood
  4. DIt rises, because CO₂ is a base
