EduSmaert Variations and Natural Selection - Smart Notes Quiz

Summary:        Differences in organisms ​ (a)   can improve survival of a species. (paragraph 1)  

• variation
• camouflage
• bioluminescence
• korbuster bird

Match the following

• Behavioral adaptation

• Camouflage

• Something an organism DOES to stay alive

  -like hibernate

• Hibernate

• Change in the organisms body functions - like bioluminescence

• Behavioral adaptation

• Physical adaption

• Physiological adapation

• A physical adaptation that helps an organisms to survive - like ladybugs color

• Structural adaptation

Which of the following about variations in species or populations is TRUE? (paragraph 1)

• Behavior variations are the only traits that help species or populations survive.

• Variation help species and populations survive

• All organisms in a population have the same vaiations

• Physical variations are the only traits that help species or populations to move on

Which of the following is NOT a reason organisms migrate?

• To reproduce

• To get more food

• To avoid being eaten by predators

• To find a more suitable climate

 Which of the following is an example of natural selection?

• Hummingbirds drinking nectar from a plant.

• Whales and dolphins swimming to the water’s surface to breathe.

• Sloths making their homes high in trees to protect themselves from predators.

• Brown-colored lizards survive and reproduce because they are better able to camouflage themselves from predators.

 A gradual change over time in a species that enables the species to better survive in its environment is known as a(n) ​ (a)   .​

• adaptation
• Habitat
• Population
• Competition

Which of the following traits is a chemical process that happens in the body of some organisms to produce light?

• bioluminescence

• Hibernation

• Migration

• Luminary

Which statement BEST describes how hibernation enhances a ground squirrel’s chance of survival?

• During hibernation, the ground squirrel’s heart rate speeds up to warm its body.

• Hibernation causes the ground squirrel to die but come back to life when the weather gets warm again.

• During hibernation, the ground squirrel moves to a warmer climate and doesn’t return until it gets warm again.

• Hibernation slows the ground squirrel’s body processes down so it uses less energy during the cold months when food is scarce.

The Venn diagram compares and contrasts migration and hibernation. What can you conclude, based on the information in the diagram?

• Both are a response to change in environment

• Migration and hibernation require organisms to move.

• A lot of energy is required for migration and hibernation.

• The only response to a change in the environment is hibernation

What do you think would MOST LIKELY happen if a particular species only came in one size, and predators ate that one size?

• The predators would get sick.

• The species would become extinct.

• The species would reproduce quickly.

• Nothing would happen to the species.
