stability

variation

complex cellular organization

a very low mutation rate

The different tools used during the beaks of finches lab represented

feeding adaptations in finches

nest construction adaptations

variations in seed size

variations in ecosystems

b) gravity

c) heredity

d) string theory

What is the advantage of having different shaped beaks?

To look different from other species.

To be able to eat the food readily available in the environment.

To protect itself against predators.

To protect itself against prey.

Why are advantageous traits more likely to be passed onto offspring?

Because they are more likely to survive and reproduce.

Because they come from dominant alleles.

Because they come from recessive alleles.

18.

Which feature helps an animal hide from other animals?

being the same color as the place it lives (camoflauge)

having sharp claws or a strong shel

having only a few young and caring for them

19.

How do adaptations help animals?

To escape animals

to hunt for food

to survive in their habitats

All of these are correct

20.

Determine if the traits are structural or behavioral.

Migration

Behavioral because it makes animals move away and find better resources

Hibernation

Behavioral because it allows animals to save energy

Camouflage

Structural because it allows organisms to hide in plain sight

Venom

Structural because it is a chemical defense

Storage of food in bulb

Structural because it allows plants to save energy for later use
