an allele is an alternative form of a particular gene whereas a trait is the character that is determined by the allele.
The nitrogen containing amino group is recycled while the remainder of the molecule is excreted in the urine
Answer:
d) The enzyme changes shape and can no longer speed up the reaction
Explanation:
Enzymes aare protein in nature therefore sensitive to changes in temperature. Most enzymes have an optimum temperature ranging from 35-40°c. As the temperature increases, optimum temperature is reached where the rate of reaction is maximum. Temperatures above 40-63°c denatures the enzymes making them non effective thus the reaction decreases sharply.
