EVERYDAY SCIENCE

Detailed explanation-1: -Together with the honey bee dance, honey bee pheromones represent one of the most advanced ways of communication among social insects. Pheromones are chemical substances secreted by an animal’s exocrine glands that elicit a behavioral or physiological response by another animal of the same species.

Detailed explanation-2: -So, the correct answer is ‘Adrenaline’.

Detailed explanation-3: -Filial imprinting. The best-known form of imprinting is filial imprinting, in which a young animal narrows its social preferences to an object (typically a parent) as a result of exposure to that object. It is most obvious in nidifugous birds, which imprint on their parents and then follow them around.

Detailed explanation-4: -Many animals use urine, and sometimes even faeces, to mark the area that they consider to be theirs – their territory. Territory marking lets other animals, of the same species, know that a conspecific is present. Urine also communicates the reproductive status of the individual and their status rank.
