Animals that live in the cold regions of the North or South Pole must adapt to special conditions. Which of these could be a helpful adaptation for an organism that lives in the North Pole?
Ability to fly or run fast
Large paws for hunting
Thick fur and layers of fat
Hard shell around the body
Many cacti live in dry habitats, such as deserts, and must store their water to use as needed. Some cacti have spines that grow in place of leaves. Spines are an adaptation that helps cacti in which of the following ways?
Allows further seed dispersal
Provides an additional food source
Increases water loss
Provides protection from animals
Many animals hibernate during the winter, when they spend most of their time sleeping. This behavior is an adaptation that helps animals in which of the following ways?
Allowing them to avoid the harsh sun and rains
Building strong muscles for fighting enemies
Conserving energy when food is hard to find
Making them easy for predators to see
Which of the following changes to the environment would most likely result in deer moving out of an area to a new habitat?
A loss of the kinds of plants they eat
Several winters with warmer temperatures
Higher water levels in a nearby river
A decrease in the number of predators
Some plants live in environments, such as dense forest, where there is a lot of competition for sunlight. Plants that live here have to find ways to receive more sunlight. Which adaptation would best help plants survive in this environment?
Bright colors to attract pollinators
Deeper roots to absorb more nutrients
Structures that allow them to climb up trees
Florida wildfires that burn down acres of trees can occur at any time of the year. This change to the environment would be most harmful to animals that depend on which behavior for survival?
Sheltering below the ground in the dirt
Flying to warmer temperatures in the winter
Pollinating wildflower as a food source
Hiding from predators high in the trees
Some animals have fur that is dark for part of the year and white for part of the year. This adaptation would be an advantage to animals that live in which kind of environment?
Heavy rain for most of the year
Seasons that include a snowy winter
A very hot and dry climate
Many forests with tall trees
A drought is a long period of time with little rainfall. What kind of adaptation would most help a plant survive a drought?
Storing water
Growing quickly
Producing seeds
Attracting insects
Some animals are adapted to survive harsh conditions. These animals drink very little and don't sweat. These adaptations make them well suited to what sort of environmental change?
A steady decrease in temperature
Earthquakes that create new landforms
A long period of time with no rain
The arrival of a new species of predator
If industrial plants accidentally leak lead into a local river, how could it effect the animals in a nearby city?
Many deer would survive because their drinking water is clean.
Many fish would die because their habitat is polluted.
Many fish can survive because the water is clean.
Many deer would die because they live in the water.
