How can you distinguish a clastic rock from that of a bioclastic rock
IRISSAK [1]

<u>Bioclastic</u> rocks are actually sub-parts of <u>clastic</u> rocks, not a completely different thing altogether.

<u>Clastic</u> rocks are made up of loosened bits of pre-existing rocks. These rocks are formed from weathering, breaking those larger rocks down into little particles (for example, a grain of sand) due to external weather factors such as wind or rain. Some examples of these rocks would be sandstone, conglomerate, and silistone. They are classified by the size and shape of the fragments they are made up of.

<u>Bioclastic</u> rocks are also made up of loosened bits, however, they are not made of rock. They are made of fossils and biogenic (made by living organisms) particles (for example, pieces of shells and coral). These rocks are formed from small parts of pre-existing organisms compacting together to form a rock. Examples of this type of rock would be coquina and limestone, or more specifically, bioclastic limestone. Bioclastic rocks have a very crystalline texture and it is highly likely that you will see a shell in this rock type.

How does the digestive system interact with the rest of the body
Ainat [17]

Answer:

The Digestive System gets nutrients (good) from food and hands it over to the blood and Circulatory System then carries those nutrients where they need to go. It Filters out waste from food and pushes it through intestines and out the body.

Explanation:

As food passes through the GI tract, it mixes with digestive juices, causing large molecules of food to break down into smaller molecules. The body then absorbs these smaller molecules through the walls of the small intestine into the bloodstream, which delivers them to the rest of the body.
