Answer:
The correct answer is option A. "Culture B will have more colonies on the histidine-minus plate than culture A".
Explanation:
In this example, Culture B is a culture of E. coli that has been exposed to a mutagenic agent, therefore it has the potential of developing bacteria that by chance, is able to live in a medium lacking histidine. On the other hand, Culture A is the same E. coli culture but without the exposure to the mutagenic agent. The expected result is that Culture B will have more colonies on the histidine-minus plate than culture A, illustrating that a mutagenic agent can produce E. coli able to reproduce in a histidine-minus plate.

Answer: C). Oxygen binding
Explanation: Hemoglobin is a protein present in the red blood cells that transports oxygen to the body cells and tissues. Hemoglobin has four subunits with four binding sites: one binding site on each protein subunit. Hemoglobin exists in two states: the tensed (T) state and the relaxed (R) state. The T state has low affinity for oxygen while the R state has high affinity for oxygen. The binding of oxygen to the T state triggers a conformational change in the protein and its transition to R state. The binding of oxygen to one binding site on hemoglobin increases the binding of oxygen to the remaining subunits, this phenomenon is known as cooperativity.
