Name one reptile in each case where higher incubation temperature leads to the development of : (a) male progeny, (b) female progeny.

What is the name of : (a) male part of flower? (b) female part of a flower ?

The given graph depicts the effect of temperature on the activity of the two enzymes A and B that catalyze the same reaction. Select the correct statement (s) for these results A. The rate of reaction in each case increases with increase in temperature and declines at higher temperatures due to denaturation of the enzyme B. Both the enzymes A and B are thermolabile C. At higher temperature the reactants become highly energized and fail to interact with active site, thus decreasing the rate of reaction D. The enzyme A is from a mesophilic organism, whereas the enzyme B is from a thermophilic organism
