they are heterotrophs, as they can not make or synthesize their own food.
Answer:
Explanation:
Most (but not all) biological macro molecules are polymers, which are any molecules constructed by linking together many smaller molecules, called monomers. If we were to string many carbohydrate monomers together we could make a polyacrylamide like starch. Proteins can be converted into energy, but your body prefers to use them for more essential jobs. Proteins build and repair every tissue in your body. They’re used to make hormones, enzymes, hemoglobin and antibodies, and they’re responsible for functions such as muscle contraction. The proteins in your body are made from 20 different amino acids. Starch or asylum is a polymeric carbohydrate consisting of numerous glucose units joined by glycogen bonds. This polyacrylamide is produced by most green plants as energy storage.
polymer: A relatively large molecule consisting of a chain or network of many identical or similar monomers chemically bonded to each other.
D. It has the same starting and ending point.
Explanation:
The defining characteristic of a water cycle is that it has the same starting and ending point. The water cycle is also known as the hydrologic cycle. It shows the cyclic path through which water moves in nature.
- The water cycle is a part of the biogeochemical cycle.
- The biogeochemical cycle shows how certain elements and compounds moves between living organisms and the earth.
- All living organisms are essentially dependent of water and it is exchanged with the environment around.
- Some key components of the water cycle are precipitation, ocean, living organisms, ground water, infiltration, surface run off, evaporation etc.
