B. Frictional force is correct
Can be methan.
Due to the decomposing process, methan is released into the air and it can be collected in some special tanks
Answer:
What would explain the change in reaction rate —degradation of cellulose by the enzyme cellulase—after 75 minutes is the depletion of the substrate on which the enzyme must act.
Explanation:
A chemical enzymatic reaction, such as cellulase degradation of cellulose, occurs until the substrate is consumed.
The solution to which cellulase is added has the same concentration of cellulose, and what is done is to add enzyme. In the graph you can see that the reaction takes place over time, decreasing the amount of glucose obtained. From 75 minutes onwards the reaction rate decreases as well as the amount of glucose obtained from the reaction, which is due to the fact that the substrate —cellulose— is being depleted.
Answer:
1. Another word for chemical weathering is b. disintegration
Chemical weathering is a process by which the rocks are broken down into parts and sediments by the action of a chemical agent such as alkali or acid. The disintegration can be a natural process by which a solid body is broken down into parts or subparts.
2. d. moving water is not an agent of chemical weathering agent.
The chemical weathering can be caused by the agents like lichens which secretes acid on the rock surface and causes it's disintegration, acid rain and salt water are chemical agents that can cause the disintegration of the rock but moving water will have little influence on the hard rock surface.
3. c. chemical weathering is a process which turns rocks and minerals into new substances. The chemical weathering process brings change in the chemical composition of the rocks due to the action of the weathering agents hence, on disintegration of rocks new substances are formed.
Answer:
All cells hace a barrier around them that separates them from the environment and from other cell.The barrier is called the plasma membrane,or cell membrane.
