Passage
Salt pans are unusual geologic formations found in deserts. They are formed in endorheic basins, which are lowland areas where water collects but has no outflow. Any rain that falls or any water that is collected in an endorheic basin remains there permanently, except for what is lost through evaporation. This type of closed system often leads to a high concentration of salt and other minerals.
Study 1
Four different salt pans around the world were studied.
The volumes of mineral deposits were estimated from the surface areas of the salt pans and the average thickness of the deposits. The ages of the salt pans were also estimated based on the mineral volume. The estimates are shown in Table 1.
Study 2
The same four salt pans were excavated for fossils. Fossil remnants of extinct plant species were found within each of the salt pans. The ages of the fossils found were similar to the ages of the salt pans (See Table 2). Scientists hypothesize that flooding of each salt pan may have led to the extinction of the plant species.
Q. From the results of Table 1, you could conclude that a salt pan formed more than 21 million years ago would have a mineral value:
  • a)
    between 5,700,000 km3 and 12,150,000 km3.
  • b)
    equal to approximately 1/2 the mineral volume of Salt pan B.
  • c)
    greater than 12,150,000 km3.
  • d)
    less than 2,000,000 km3.
Correct answer is option 'C'. Can you explain this answer?

The best answer is C. Since there is a direct, positive relationship between salt pan age and mineral volume, if a salt pan were to have formed before the oldest salt pan in the study, then it would likely contain a greater volume of minerals than that pan is shown to contain. Since the oldest pan in the study contained 12,150,000 cubic kilometers of minerals, a pan older than that would have a higher mineral value.

A control consisted of bacteria incubated in the medium without any drugs. The bacteria were washed to remove residual drug traces and grown on nutrient agar plates for 7 days. During this time, the bacteria reproduced, forming colonies, which were then counted at the end of the seventh day. Plates with more colonies were assumed to have more live bacteria at the end of the 1-hour incubation period. Table 1 shows the number of colonies counted. The drug-free control showed 50 colonies at the end of 7 days.Experiment 2Bacteria were handled as described in Experiment 1 with two exceptions: all drugs were tested at the same concentration and the incubation time of each culture was varied. Table 2 shows the number of colonies counted for Experiment 2.Experiment 3Permeability coefficients measure a drug’s ability to break through the cell membrane of a bacterium. The larger the permeability coefficient, the faster the drug is able to transfer through the membrane. The molecular mass, in atomic mass units (amu), and permeability coefficient, in centimeters per second (cm/s) of the 5 drugs at 37 C were measured. The results are shown in Table 3.Q.In Experiment 1, what was the relationship between drug concentration and the drug’s effectiveness in killing penicillin-resistant bacteria?
