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.

Answer:
Genes are important for determining function, but nutrition modifies the extent to which different genes are expressed and thereby modulates whether individuals achieve the potential determined by their genetic background. Nutrition modifies both physical and cognitive aspects of performance.

Answer:
The correct answer will be option-D
Explanation:
Apoptosis is the process which leads to the death of the cell which is programmed and thus is known as the programmed cell death.
The death of a cell takes place when the cell experiences the lack of survival signals either due to the need to kill the cell or some genetic defects in DNA contained in cells.
The cell which undergoes apoptosis process can be easily marked by their shape as it gets shrunk, the cytoskeleton of the cell collapses, irregular bulges called blebs and the disassembly of the nuclear envelope.
Since the cell shrinks instead of swelling, therefore, option-D is the correct answer
