The letter that represents enzyme is B.
Given what we know, we can confirm that the biome is in fact an open system due to the interactions between the biosphere, atmosphere, lithosphere, and hydrosphere.
<h3>What is the biome?</h3>
- The biome is the collection of air, soil, water, and all the organisms that reside within these ecosystems.
- In order to describe an open system, we say that the system must have external interactions.
- A biome is an open system because it has both internal and external interactions, such as with asteroids in space.
- The internal interactions include the ones between the<em><u> biosphere, atmosphere, lithosphere, and hydrosphere.</u></em>
- A prime example is the movement of water through each of the spheres.
Therefore, since each part of the biome interacts with each other as well as with external sources such as space, we can confirm that it complies with the definition of an open system.

The intervertebral discs, which are between vertebrae, are the parts that prevent the vertebrae from grinding against one another.
The intervertebrals discs act as a cushion; they absorb the stress and shockw that occur during movement, preventing such grinding.
Explanation:
<u>The stomach </u>
Digestion describes the intake, chemical and physical breakdown, absorption of nutrients and excretion of food with the use of enzymes. The stomach secretes the enzyme, gastric lipase to digest fats.
Further Explanation:
Food is chemically and mechanically broken down into smaller particles. In the stomach the enzyme gastric lipase acts on lipids, breaking them up into their components. Phospholipids, bile acids, bilirubin, and cholesterol are combined into bile in the liver, which when secreted into the duodenum of the small intestine; this comes from its storage site, the gall bladder, and functions as an emulsifier or as a detergent.
These hold the fats and water together and increase the surface area of lipids, which can be further digested by enzymes so the nutrients are further broken down for absorption into the bloodstream.
