Which of the following adaptations helps birds fly?
They have more fat than most animals, so they can fly for long distances.
They have hollow bones, so they are lighter.
They have smaller blood vessels, so their hearts have to work less in flight.
They have a larger stomach, so they can absorb food faster.
A puppy has a pattern of spots on its fur that is similar to that of its parents. Where are the instructions stored that provide information for a puppy’s fur pattern?
In the mitochondria
In cytoplasm inside cells
On genes within chromosomes
On the cell membrane
Many birds, such as the barn swallow, have hollow bones, while a few birds, such as the ostrich, have solid bones. Which best explains this adaptation that are seen in birds?
Hollow bones allow for a lighter body weight for flight.
Hollow bones allow for more space for making more red blood cells
Larger birds need solid bones to hold the weight when standing.
Solid bones are an advantage because hollow bones are too brittle..
A desert is a biome that can have extremely harsh living conditions. Which of the following adaptations do NOT help animals survive in this type of environment?
Animals add fur to maintain their bodily temperatures.
Water is stored in fatty tissues in the body.
Animals burrow deep in the ground during the day.
Many animals are nocturnal which helps them avoid sunlight
