Answer:
The involvement of more than two genes.
Explanation:
The polygenic characteristics have many phenotypes because more than two genes governs the phenotype of individual organism. The single gene contains a pair of alleles that codes for two phenotype and two genes will code for 4 phenotype. Thus, more than two genes for example, three genes will have six phenotypes.
The skin color and height are polygenic characterstics in humans.
Answer:
<u><em>This is because the enzymes might work best at higher temperature than 37 degrees Celsius. Increase in temperature will increase the catalysis of the reaction.</em></u>
Explanation:
<em>When the temperature is increased, the molecules possess greater kinetic energy. This will allow more substrate and enzymes to collide. As a result, there will be more enzymes taking place in the reaction which will cause the rate of the reaction to increase.</em>
<em></em>
However, if the temperature goes too high, then the shape of the active site of the enzymes will get changed. The enzyme will deactivate and the reaction will stop.
