As you can see in the diagram presented below, the two genes are on the same chromosome, but they are very far apart from each other.
Why is this important?
Genes on the same chromosome can be separated in a process called the crossing-over. The crossing over is a process that occurs in meiosis in which the two homologous chromosomes randomly exchange parts of their sequence. The farther apart the two genes are on the chromosome, the more likely is that during crossing over they will be separated. Likewise, the closer the two genes are the more likely it is that they will cross-over to the other chromosome together.</span>

Answer:
The correct answer is option b. "Enzymes display high specificity with respect to their substrates".
Explanation:
One of the characteristics of most enzymes is their high specificity towards their substrates. This is illustrated in the experiment herein stated. Glucose is the main substrate of Hexokinase, since it catalyzes the reaction between glucose and ATP to form glucose 6-phosphate and ADP. In this experiment, different sugars were substituted for glucose in Hexokinase's reaction , and the results show that the relative rate of reaction was reduced to 0.4 in the case of mannose, and up to 0.0 in the case of xylose. Since no sugar was able to have the same relative rate of reaction as glucose, we can conclude that Hexokinase is highly specific to its substrate.
The answer is to function as the final electron acceptor in the electron transport chain. It is the only place that O2 partakes in the cellular respiration is at the end of the electron transport chain as the final electron acceptor. Oxygen's high affinity for electrons safeguards its success in this role. Its assistances to driving electron transport, forming a proton gradient, and synthesizing ATP are all indirect effects of its role as the terminal electron acceptor.
