How could the increasing global temperature associated with climate change impact ectotherms?
- Ectotherm diversity will decrease in cool regions.
- Ectotherms will be able to be active all day in the tropics.
- Ectotherms will have to expend more energy to cool their body temperatures.
- Ectotherms will be able to expand into new habitats.
Although most animals are bilaterally symmetrical, a few exhibit radial symmetry. What is an advantage of radial symmetry?
- It confuses predators.
- It allows the animal to gather food from all sides.
- It allows the animal to undergo rapid, purposeful movement in any direction.
- It lets an animal use its dorsal surface to sense its environment.
