Answer 1

Thousands of golden toads, shown below, used to occupy the tropical forests of Costa Rica. In the late 1980s, however, unusually warm weather caused many of the pools that the toads used as breeding areas to dry up. By 2004, the golden toad was listed as extinct. This example demonstrates how:(1 point)

Answer 2

All cells come from pre-existing cells.

Answer 3

The example given demonstrates how extinction can be related to a failure to adapt to changes in the environment.

In this case, the unusually warm weather caused the pools that the golden toads used as breeding areas to dry up. This change in the environment affected the ability of the golden toads to reproduce and survive. As a result, the population declined and eventually led to their extinction. This highlights the importance of adaptation to changing environmental conditions for the survival of a species.
