Final answer:
The organisms W, X, Y, and Z respond to the antibiotics ferromycin, ganocyclene, and heptocillin in a manner consistent with the following:
Conditions:
W responds to ferromycin if and only if Z responds to ganocyclene.
Y does not respond to heptocillin if and only if X responds to ganocyclene.
Z responds to heptocillin if W responds to ganocyclene. a) W organism responds to ferromycin.
Step-by-step explanation:
a) Organism W responds to ferromycin because the conditions state that W responds to ferromycin if and only if Z responds to ganocyclene. Since Z responding to ganocyclene is the prerequisite for W's response to ferromycin, and we are not provided with any contradictory information, the conclusion is that W is the organism that responds to ferromycin. The conditions do not establish a direct relationship between ferromycin and any other organism.
The logical sequence of responses among the organisms can be deduced by analyzing the given conditions. By understanding the interconnections between the responses to different antibiotics, we can unravel the relationships between the organisms.
In this case, the crucial link is between W and Z, where W's response to ferromycin is contingent upon Z's response to ganocyclene. No other direct relationships between the organisms and ferromycin are specified in the given conditions, reinforcing the determination that W is the organism that responds to ferromycin.
Careful consideration of the conditions and their implications is essential to derive the correct answer. Each statement contributes to the logical framework governing the responses of the organisms to specific antibiotics. By adhering to the established relationships and prerequisites, we can confidently identify organism W as the one that responds to ferromycin.
