What characteristic did Darwin observe about the finches on the Galapagos Islands?
Their feathers
Genotypes
Their beaks
Their body sizes
Some organisms have colorful appearances to warn their predators (animals that would try to eat them) that they are harmful or do not taste good. If other species, that are not harmful, mimic these colors how would that help them reproduce?
The bright colors would help them attract more mates and allow them to reproduce
Because they have similar colors they can mate with the harmful species to create hybrids
Bright colors help them be more visible in the dark and most mating occurs after dark
The similar markings and colors will increase their chance of predators avoiding them and allow them to survive to reproduce
This gecko is an example of what type of adaptation?
Behavioral: Camouflage
Behavioral: Migration
Physical: Camouflage
Physical: Migration
Why do frogs and other organism reproduce so many eggs or offspring?
so that their babies can have friends to play with
the more offspring the more likely the offspring will survive
the more offspring the less likely offspring will survive
the more offspring the less competition
a bird that can easily outcompete other birds for food and that can produce many eggs has a high
life expectancy
mutation rate
fitness
adaptability

Which of the following best describes natural selection?

What is an example of an adaptation in polar bears that helps them survive in cold environments?
Thick fur and a layer of fat for insulation
Sharp claws for climbing trees
Long legs for running fast
Brightly colored fur for camouflage
In an experiment, a population of insects is exposed to a pesticide. Over time, the population becomes resistant to the pesticide. What is this an example of?
