females of different species attract males by emitting chemi

females of different species attract males by emitting chemical signals that spread through the air. Males at big distances can detect these molecules and run toward their source they have sensory organs responsible for this behavior. Based on what you learned in this chapter, propose a hypothesis to account for male’s ability to detect a specific molecule among many other molecules in the air. How would you test your hypothesis?

Solution

females or males sense the opposite sex by the chemical signals called pheromones. these signals will help the other animals to sense the oppsosite sex. olfactory receptors present in the nose. Chemical signalling will help females attract males for their reproductive needs and also prevents inbreeding, helps to identify high quality males in terms of their genes. Odorant molecules when bind to the receptors present in the nostrils will sense the pheromones. odor typesare distinguished with interaction of odor molecules with different types of olfactory receptors. Properties of an odor molecule are functional in determining the degree of interaction with a olfactory receptor, time of interaction and thus in determining its perceived odor quality.

hypothesis and the detection is simple that the human sense of perception of smell can be distinguishable. the very easy method would be to get to a perfumary or perfume shop and sniff for various perfumes and inbetween distingush by smelling coffee beans.
