Which document made provisions for federal authority in the west but prohibited the spread of human bondage?.
Amanda [17]

Missouri Compromise made provisions for federal authority in the west but prohibited the spread of human bondage.

What is Missouri Compromise?

  • The Missouri Compromise Act, passed by the US Congress in 1820, admitted Missouri as the 24th state to the Union.
  • Northern congressmen attempted unsuccessfully to attach amendments preventing further slaveholding after the area requested sovereignty without constraints on slavery.
  • When Maine (which was once a part of Massachusetts) applied for statehood, Henry Clay brokered a deal that saw Maine admitted as a free state and Missouri admitted as a slave state.
  • Slavery was subsequently outlawed in areas north of Missouri's southern boundary.
  • Clay's solution highlighted the sectional divide while appearing to resolve the slavery-extension issue.

nekit [7.7K]
I think the correct answer from the choices listed above is option A. If the reaction of maltase is optimum at the pH range of 6 to 7, then most likely when the ph is decreased into three maltase would not be able to function outside of its optimal pH range. Hope this answers the question.
