An experimenter tries to determine the molecular weight to glucose by observing the depression in freezing point. He carries out his experiment in duplicates. In one he uses pure water as the solvent and in the other independent experiment by mistake, he uses a `0.1 N` aqueous `NaCl` as the solvent. It is expected that he will report:

Identify the ecologist from the given hints (i) He carried out long term ecosystem experiments using outdoor plots (ii) In his experiments he showed that "increased diversity contributed to higher productivity".

Consider the transistor shown in figure, its terminals are marked as 1,2 and 3. Using multimeter one try to identify the base of transistor, he proceed in the way as follows. Experiment I: He touches the common lead of the multimeter to 2, then on touching other lead of multimeter to 1 he hasn.t got any beep (indication of conduction) but when connected to 3 got the beep. Experiment II: He connected the common lead of multimeter to 1 and other lead to 2 and 3 one by one then in this case he got beep for both connections. From this we conclude that

Raj performs an experiment to know the conducting nature of some of the objects using a circuit, as shown in the given figure. He inserts some objects one by one between M and N and observes whether the bulb glows or not. The objects that he inserted are eraser, key, plastic scale, glass bangle, bottle cap, nail, thermocol sheet, and wallet. Raj will be able to glow the bulb if he inserts
