Which of the following Python lines returns subset data for only the variables "survived" and "age" from a dataframe called "titanic"? a) titanic[['survived','age']]
b) [['survived','age']]titanic
c) titanic_read_variables[['survived', 'age']]
d) titanic('survived','age')

the answer is; biodiversity resulting from few ancestors

adaptive radiation occurs when a population is subjected to a large natural environment with spatial ecological variations. the parts of the population in the different ecologies begin to adapt to their local environments. due to non-random mating across the large populations, this causes the different populations from the large population to speciate within their local environments. they, therefore, diverge to different species sharing a common ancestor.
