Question

which of the following is an example of variation within a population of mexican free-tailed bats? select the correct answer. some bats travel over 50 miles in a night to find food, while others do not travel as far. all bats use echolocation to hunt and navigate in the dark. every bat migrates between mexico and texas at the same time each year. bats roost in large colonies to stay safe from predators.

Explanation:

To determine variation within a population, we look for differences among individuals.

• Option 1: "Some bats travel over 50 miles in a night to find food, while others do not travel as far" shows differences in travel distance, which is variation.
• Option 2: "All bats use echolocation..." describes a shared trait, not variation.
• Option 3: "Every bat migrates... at the same time" describes a uniform behavior, not variation.
• Option 4: "Bats roost in large colonies..." describes a shared behavior, not variation.

Answer:

A. Some bats travel over 50 miles in a night to find food, while others do not travel as far.
