Answer:
The shape of an enzyme determines which reaction it can catalyze.
Explanation:
Each enzyme is specific to one type of reaction. According to the structure of each enzyme, it has an active site capable of binding to a specific substrate, so the shape of the enzyme determines the type of reaction to be catalyzed.
Once the reaction occurs, the enzyme releases the product of the reaction and the enzyme is available for another reaction.
Regarding the other options:
- <em>The shape of an enzyme no depends on the reaction that it needs to catalyze.
</em>
- <em>Due to their specificity, enzymes can only catalyze one reaction at a time</em>
- <em>The shape of the enzyme is not altered after the reaction.</em>
Ecotones are the<u> transitional zones between two ecosystem.</u>
Explanation:
Ecotones is a narrow zone between two different ecosystem.
It may be defined as the transition zone between these two ecosystem. Ecotones are species rich and it's resources are used by inhabitants of both the ecosystem.
Ecotones are marked by sharp changes in vegetation and species population.
The ecotones arise due the drastic changes in the environmental condition of a place that creates a sharp boundary between it and adjacent area.
However, these changes blend somewhere in between these area and results in formation of ecotones.
Example of ecotones can be the mangroves. These lie between marine ecosystem and terrestrial ecosystem.
D. Fossil fuels are the remnants of organisms that lived a long time ago and were buried, heated, and formed into hydrocarbons.
The division of the autonomic nervous that is short-lived and very localized is parasympathetic system.
What is nervous system?
The nervous system includes the brain, spinal cord, and a complex network of nerves. This system sends messages back and forth between the brain and the body. The brain is what controls all the body's functions. The spinal cord runs from the brain down through the back. The parasympathetic nervous system predominates in quiet “rest and digest” conditions while the sympathetic nervous system drives the “fight or flight” response in stressful situations.
The main purpose of the PNS is to conserve energy to be used later and to regulate bodily functions like digestion and urination.

Energy used since long time ago is a energy production system where the energy is joined with the new resources and alll of that turns into electric energy!<span />
