Answer:

The article revealed the fact that Black inventors have always played an active role in inventing new things in America. In the 18th and 19th centuries they were denied the right to patent their inventions because of their status as slaves. This has changed for the better in present times as many Black inventors are being granted patent rights.

Explanation:

The article, "America’s always had black inventors – even when the patent system explicitly excluded them", by Shontavia Johnson, explained the active role that Black Americans, both free and slaves played in inventing things in the United Slaves. The article explained that although the patent rights signed into the constitution in 1787 was written in a neutral tone, it did not change the fact that black inventors were actually denied patent rights.

This segregation affected people like Henry Boyd, Ned, Benjamin Montgomery among others. In recent times, this segregation has significantly been curbed as many Black inventors are now owners of patents. An example is Lonnie Johnson, inventor of the Water Gun and owner of more than 80 patents.

What are the priority functions of the gallbladder and why it is essential to aid in digestion?
enot [183]

The repository of bile produced by the liver is one of the gallbladder's top priorities.

Bile is required to break down the body's fats and lipids, making it vital for digestion. In addition, it helps in the metabolism of bilirubin, which is produced when RBCs break down.

The gallbladder serves several essential purposes, including the following:

  • To store and purify bile
  • The ability to empty and restock its bile reserves in response to intestinal hormones like cholecystokinin.
  • To assist in controlling the bile's chemical makeup (the percentage of water, bile salts and more)
  • To regulate the small intestine's bile flow.
  • To contract (secreting bile into the biliary tract and duodenum)
