The graph below shows  the  growth  rates  of  populations  of  bacteria  that  have  evolved  for  many  generations  at different culture temperatures (25°C, 30°C, and 35°C). Each population grows over only a limited range of temperatures (its thermal niche), which are bounded by its critical thermal limits. Within this range, growth rate increases with temperature up to a maximal value and then declines rapidly with increasing temperature. Growth rates are known to be the major determinant of fitness for these bacteria.

Which of the following is true concerning the thermal dependence of growth rate   between 25°C and 30°C in these populations?

In a toy, two men with red and blue caps are moving in two different circular paths of same radii. When the man with red cap moves 3 steps, the one with blue cap moves 5 steps in the same time, but the distance traversed by the man with red cap in 5 steps, is equal to the distance traversed by the man with blue cap in 4 steps. What is the number of rounds the man with red cap made the man with blue cap completed 100 rounds?
