In adjacent agricultural lands of nearly equal dimensions, two farmers A and B had cultivated crops of their choice and observed standard practices. A pathogen attacked the crops and destroyed it in the land belonging to farmer A, as a result of which he suffered complete loss. Although the pathogen attacked the adjacent land belonging to farmer B, he was able to earn some money by selling the yield. The possible explanation for the above is:

Virulent forms of the bacterium. staphylococcus aureus is a human. pathogen, some strains of which cause "flesh-eating disease". Earlier the antibiotic Penicillin was used to control this pathogen. After some years Penicillin was ineffective. Hence, a powerful antibiotic-Methicillin was used in treatments. Subsequently, Methicillin also became ineffective and the strains showed resistance to multiple antibiotics also called "multi-drug resistance". Which one of the following statements regarding development of multi-drug resistance is correct?

Detergents are also called surface active agents (surfactants). These have two distinct parts: one hydrophilic spherical part and another hydrophobic long tail made of carbons chain. Two experiment 'A' and 'B' were carried out. In experiment 'A', surfactant was added in a beaker containing water. In experiment 'B', surfactant was added in a beaker containing hexane. Following are possible results in these experiments. I. In experiment 'A'(see figure) 'a' micelle is formed, where hydrophobic part is inside the micelle and hydrophilic part is outside the micelle. II. In experiment 'B'(see figure 'b') micelle of reverse type is formed where hydrophilic part is inside the micelle and hydrophobic part is outside the micelle. III. Micelle of reverse type is formed in experiment 'A'. IV. Micelles are large enough to scatter light in 'A'. Correct observations are
