Answer: Option E) None of the above is true; this enzyme could bind none of these.
Explanation:
Lactose is a dissacharide composed of glucose and galactose. Hence, the enzyme lactase break down lactose into its simple sugar constituents.
However, lactase cannot bind nor break down amino acids, starch (with only glucose units) or sucrose (with two glucose units) because their constituent molecules differ markedly from that of lactose.
Thus, the enzyme lactase could bind with none of the options provided except lactose

Answer:
A. dihybrid crosses
Explanation:
A dihybrid cross can be defined as a mating experiment between two lines/varieties/organisms that differ in two phenotypic traits. By using pea plants, Mendel performed dihybrid crosses in order to analyze the mode of inheritance of both phenotypic traits at the same time. From these mating experiments, Mendel observed that the inheritance factors (nowadays called genes) sorted independently from one another in the next generation, which is called the principle/law of Independent Assortment.
