How can variations within a population of rabbits be an advantage when the environment changes to a colder climate?
All rabbits will struggle to survive regardless of their variations.
Rabbits with thicker fur may survive better in colder climates.
Variations do not affect survival in changing environments.
Only rabbits with longer ears will survive.
A population of insects lives in a forest. If the forest experiences a drought, which variation might be a disadvantage for the insects?
Insects with a thicker exoskeleton.
Insects that require a lot of water.
Insects that can fly long distances.
Insects that can burrow underground.
Consider a population of fish in a lake. If the water temperature increases, which variation might help some fish survive better than others?
Fish with a preference for colder water.
Fish with a higher tolerance for warm water.
Fish that swim slower.
Fish with brighter colors.
Why might a population of birds with varied beak sizes have an advantage in a changing environment?
All birds will eat the same food regardless of beak size.
Birds with different beak sizes can exploit different food sources.
Beak size does not affect survival.
Only birds with the largest beaks will survive.
A population of plants has some individuals with deeper roots. How might this variation be advantageous during a drought?
Plants with deeper roots can access water from deeper soil layers.
All plants will die regardless of root depth.
Deeper roots make plants more susceptible to drought.
Root depth does not affect water access.
In a population of lizards, some have the ability to change color. How might this be an advantage in a changing environment?
Color-changing lizards can better hide from predators.
All lizards will be equally visible to predators.
Color-changing does not affect survival.
Only lizards that do not change color will survive.
A population of deer lives in a forest that is becoming more urbanized. Which variation might help some deer survive better?
Deer that are more afraid of humans.
Deer that can adapt to eating human food.
Deer that only eat forest plants.
Deer that are less adaptable to new environments.
How might a population of frogs with varied skin colors have an advantage in a changing environment?
All frogs will be equally visible to predators.
Frogs with skin colors that blend into the environment can avoid predators.
Skin color does not affect survival.
Only frogs with the brightest colors will survive.
A population of birds is experiencing a change in available food sources. How might variations in beak shape be advantageous?
All birds will eat the same food regardless of beak shape.
Birds with beak shapes suited to new food sources will survive better.
Beak shape does not affect food access.
Only birds with the largest beaks will survive.
A population of insects is exposed to a new pesticide. How might genetic variation within the population be advantageous?
All insects will be equally affected by the pesticide.
Some insects may have a genetic resistance to the pesticide.
Genetic variation does not affect pesticide resistance.
Only insects with the largest wings will survive.
In a population of wolves, some individuals have a thicker coat. How might this variation be advantageous if the climate becomes colder?
All wolves will be equally affected by the cold.
Wolves with thicker coats will be better insulated against the cold.
Coat thickness does not affect cold resistance.
Only wolves with the longest legs will survive.
A population of fish is introduced to a new predator. How might variations in speed be advantageous for survival?
All fish will be equally vulnerable to the predator.
Faster fish can escape predators more easily.
Speed does not affect predator avoidance.
Only fish with the largest fins will survive.
A population of plants is exposed to a new herbivore. How might variations in leaf toughness be advantageous?
All plants will be equally affected by the herbivore.
Plants with tougher leaves may be less palatable to the herbivore.
Leaf toughness does not affect herbivore resistance.
Only plants with the tallest stems will survive.
In a population of birds, some individuals have longer wings. How might this variation be advantageous if the environment changes to require longer migrations?
All birds will be equally capable of long migrations.
Birds with longer wings can fly longer distances more efficiently.
Wing length does not affect migration ability.
Only birds with the brightest feathers will survive.
A population of mammals is experiencing a change in available food sources. How might variations in digestive efficiency be advantageous?
All mammals will digest food equally well.
Mammals with more efficient digestion can extract more nutrients from new food sources.
Digestive efficiency does not affect nutrient extraction.
Only mammals with the largest teeth will survive.
