(i) Find the time interval between successive maxima of the intensity of the signal received by the detector. (ii) Find the time for which the detector remains idle in each cycle of the intensity of the signal.

Which of the following statement is true for variation in organisms? (1) The occurrence of differences among the individuals of the same species is known as variation. (2) Variations decrease the possibilities of survival. (3) The process of evolution decreases the variation in organisms. ( 4) During meiosis, crossing over takes place between the genes and hence, new combinations are formed, which ultimately results in producing variations.
