By low temperature, it can melt. High pressure will raise the melting point of the rock.
<u>Answer</u>: works optimally at 20°C
Enzymes are a broad group of biological catalysts that have the role of accelerating chemical reactions by binding to molecules and altering them in specific ways. They are essential to the correct functioning of the body.
Enzymes function only at certain temperatures and pH ranges. The enzyme shown in the graph works optimally at 20°C. This is shown by the fact that the reaction rate, enhanced by the enzyme, reaches a maximum at this temperature. The higher the temperature, the more effective the enzyme.
However, at temperatures higher than this optimal threshold, the enzyme will gradually decrease in efficiency. To high or low temperatures will have this effect.
The speciation process is best defined as the development of a new species (c).
Answer:
Not being able to adapt creates competition from those who can adapt. This is called the survival of the fittest. New predators and loss of habitats create environmental pressures that can limit the growth of a population and lead them to extinction if they are unable to adapt. The faster the change occurs, and the more drastic the change is with respect to the way that species lives, the more likely it is that the species will not be able to adapt in time and may disappear. This is also called Natural selection.
