One evidence of evolution is that similar structure from related species were inherited from a common ancestor. What is the term called for this evidence?
Fossils
Genetic Variation
Homologous Structure
Natural Selection
The image shows different colors of fur in giraffes. What is the environmental pressure in this example?
Color of the environment
Climate change
Color of the prey
Color of the predator
The image shows different colors of fur in giraffes. Does different color of fur support or refute the theory of evolution?
It supports the theory of evolution because it demonstrates genetic variation within a species.
It refutes the theory of evolution because not all the species are the same fur color.
It refutes the theory of evolution because giraffes can't change the color of the fur.
It supports the theory of evolution because it was visible in their fossils.
A penguin can hold its breathe underwater for 22 minutes. The ability to do this is an example of what term?
Adaptation
Natural Selection
Genetic Variation
Limiting Factors
What is the term of factors that are living in an ecosystem?
Biotic
Abiotic
Limiting
Adaptation
Five hundred Bacteria of one species were sprayed with a new antibiotics. two days later all of them died. A few, however, survived. This outcome illustrates which one of
Darwin’s key ideas about natural selection and variation?
All living things come from preexisting living things
Animals adapt to new environments.
There is variation among individuals within a species.
New species develop from survivors.
The image demonstrates the evolution of horses. What is true above the theory of evolution regarding horses?
The evolution of horses happened quickly.
The evolution of horses happened over thousands of years.
The evolution of horses happened over long periods of time.
The evolution of horses did not happen.
Which type of butterfly will be less likely to become extinct in the environment shown in the picture?
Before the invention of the lightbulb, Americans burned oil in lamps for light. Whale oil was popular biofuel for these lamps. Ship crews would hunt whales for their oil. They searched for the largest whales they could find so that they could obtain as much whale oil as possible. How mighty decades of whale hunting possibly affect the natural selection of the species?
The whales lost their legs.
The whales became slower.
The whales became smaller.
The whales changed their calls
Why do scientists study fossils?
to learn how the planet was formed
to study how organisms changed over time
to observe how drought affected the landscape
to understand how weathering affected rock layers
Chameleons can change color to match the color of their surroundings. If a chameleon was born with a mutation that prevented it from being able to change color, why would it be unlikely to pass on this trait?
The gene would mutate again before it was passed on
The trait would be recessive, so it would not be passed on
The chameleon would be unlikely to survive long enough to reproduce and pass on the trait.
The chameleon would have to find another chameleon with the same trait to pass the trait on
What term describes what the butterfly is doing in the picture?
migrating
hibernating
mimicry
camoflauging
What is the change or ability an organism goes through to fit better with its environment?
Adaptation
Natural Selection
Environmental pressures
Fossils
What are activities or factors that cause the environment to change?
Adaptation
Environmental Pressures
Biotic Factors
Fossils
New species of organisms are descendants of species in the past. What does this support?
Theory of Plate Tectonics
Law of Superposition
Theory of Evolution
Law Conservation of Energy
