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.
Biology.
The science of biology is a systematic and organized body of delving into and about life.
Anything that has life.
Studying life, animals, plants, protists and the interactions.
A biological system<span> or also called, a biotic community is composed mainly of living organisms. These organisms can be classified into the main layman categories of animals and plants, majorly. These creatures can be more furthered classified by how they eat and survive. Plants can make their own food through, photosynthesis. Animals eat and are dependent. Can be classified into subtypes as: herbivores, omnivores and carnivores. What makes all of these organisms a biotic community or a biological system is they contain cells, cells are the basic unit and foundation of every living thing. </span>

1. Thunder is caused by the rapid expansion of the air surrounding the path of a lightning bolt. ... From the clouds to a nearby tree or roof, a lightning bolt takes only a few thousandths of a second to split through the air. The loud thunder that follows the lightning bolt is commonly said to come from the bolt itself.
2. thunderstorms mostly occur in rainforests. Some of the most powerful thunderstorms happen in the United States of America.
3. Cumulonimbus is a dense, towering vertical cloud, forming from water vapor carried by powerful upward air currents. If observed during a storm, these clouds may be referred to as thunderheads. Cumulonimbus can form alone, in clusters, or along cold front squall lines.
4. The air cools as it rises. Water vapor condenses and forms cumulus clouds. When condensation occurs, heat (latent heat/energy ) is released and helps the thunderstorm grow. At some point, condensation high in the cloud (now in the form of water droplets and ice) falls to the ground as rain.
