A botanist finds that when compared to pink flowers, the population of purple flowers is very high. Ten years later, the population of purple flowers is nearly gone, and the number of pink flowers has tripled. Why would this be?

the cell theory states that all living things including animals, as well as plants, are made of cells.

i have to report this, it doesn't relate to biology

its 42

i say its d?

tsd is temerature dependent sex determination.

tsd: it is a type of environmental sex determination in which the temperature experienced during embryonic/ larval development (ambient temperature for development) determine the sex of the offspring.

crocodile displays the tsd where the ambient temperature of the developing egg determines the individual's sex. for example in the american alligator's eggs, incubation at 33 ºc produces mostly males, while incubation at 30 ºc produces mostly females. so if the american alligator's egg will get the ambient temperature (33 degree celcius)during embryonic development from egg, the offspring will be male and same for the female sex determination.
