(05.04 MC) This figure is a graph. The y-axis is labeled"reaction rate," while the x-axis is labeled"temperature" in degrees Celsius. The x-axis ranges from 0 to 35. The plot line begins near the bottom of the y-axis at a temperature of zero. At a temperature of 10, the plot line begins to increase gradually, peaking between 15 and 20 degrees. The plot line then gradually descends, returning to its starting point at a temperature of about 33 degrees.

Based on the graph, this enzyme works optimally at 5°C works optimally at 33°C begins to denature above 25°C

1. true.2. true.3. true.4. false.5. true.the concept of darwin's theory of evolution involves the idea that there are limited resources in a given living environment and that the organisms which live within have variations in their genetic make up due to random mating. the ones with beneficial genetic variations can express certain traits which give them an upper hand in surviving and reproducing in the said environment compared to ones who may have a more disadvantageous variation in traits. over time, the organisms with an upper hand will survive and reproduce more frequently and pass on their beneficial genes while the others die. the result is evolution, where we observe (usually, but not always) eventually, phenotypic distinct changes.
