Question

How would reducing low-growing plants from an area impact a population of tortoises with two varieties of neck extension ability: short and long distance?(1 point) Responses The variety of tortoises with the ability to extend their necks a long distance would go extinct. The variety of tortoises with the ability to extend their necks a long distance would go extinct. The variety of tortoises that could only extend their necks a short distance would go extinct. The variety of tortoises that could only extend their necks a short distance would go extinct. The proportion of tortoises with the ability to extend their necks a long distance would increase. The proportion of tortoises with the ability to extend their necks a long distance would increase. The proportion of tortoises that could only extend their necks a short distance would increase.

Answer 1

Reducing low-growing plants from an area would likely impact the tortoise population differently based on their neck extension abilities. Specifically, the variety of tortoises with the ability to extend their necks a long distance would have a survival advantage since they could reach food sources that smaller tortoises could not. Consequently, over time, the proportion of tortoises with the ability to extend their necks a long distance would increase because they are better adapted to the changing environment where low-growing plants are scarce.

Therefore, the most appropriate response is: The proportion of tortoises with the ability to extend their necks a long distance would increase.
