Answer 1

In a 12-month period, with 70 giraffe births and 45 deaths, the giraffe population increased by 25 giraffes.

Step-by-step explanation:

The population change in a population of giraffes over a 12-month period can be calculated by subtracting the number of deaths from the number of births.

Since 70 giraffes were born and 45 giraffes died, the population change is found by calculating 70 births minus 45 deaths, which results in a net increase of 25 giraffes. Therefore, the correct answer is B. The population increased by 25 giraffes.
