For a scientific experiment, a physicist must make sure that the temperature of a metal does not get colder than -144°C or the metal will not be usable. The physicist changes the metal's temperature at a steady rate
of -8°C per hour.
Part 1 out of 3
Lett represent time in hours. Enter an inequality. Use the fact that the rate of change in temperature times
the number of hours equals the final temperature.
The inequality is

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.  

i think the answer would be c
