Answer:
Enzymes work by binding to reactant molecules and holding them in such a way that the chemical bond-breaking and bond-forming processes take place more readily. Basically, it reduces the activation energy and makes the reaction occur faster.
Answer:
Stream volume and speed directly affects the size, shape, and flow of streams and rivers.
Explanation:
- The greater volume results in larger channels and these larger channels will make the flow of stream faster.
- The flow volume of different streams are related to precipitation and run-off.
- The earth materials also heavily effect the flow by changing the properties of the water like increase in the mass, hardness, shape, etc.
- Erosion and deposition is common in the curving type of stream.

Answer:
Mitochondria and some prokaryotes share similar metabolic reactions that produce ATP.
Correct. The observation that mitochondria and some prokaryotes share similar metabolic reactions that produce ATP supports the model that mitochondria are endosymbionts that originated from a free-living prokaryote.
