|
What do fish and amphibians have in common? (Hint: Include reproduction amongst other characteristics) |
Both amphibians and fish lay eggs in or near water however, fish develop the eggs inside the mom before laying them. The process of fertilization happens outside the body for amphibians while it is internal for fish. amphibians live a part of their life in the water but leave the water for their adult stage and the juveniles have gills just like fish. |

|
What do amphibians and reptiles have in common? (Hint: Include reproduction amongst other characteristics) |
Both reptiles and amphibians lay eggs, reptile fertilize the eggs internally while the fertilization for amphibians is external. Amphibian eggs have no shell around then while reptile eggs do have a shell around them. Both have a cloaca. |
|
|
Birds are classified in the reptile group. What characteristics cause biologists to put them into this class? (Hint: Include reproduction amongst other characteristics) |

What is ethology? |
The study of animal behavior under natural conditions. |
|
|
What are the two purposes of all animal behavior? |
The two purposes of animal behavior are to survive and to reproduce. |
|
|
What is the difference between proximate causes of behavior and ultimate causes of behavior? |
The difference between proximate and ultimate causes of behavior is, proximate= in the body (how/physically) ultimate= in the end/ what it leads to |
|
|
Give an example of a proximate cause question and ultimate cause question. |
How does the animal use its motor or sensory abilities to activate and modify its behavior? |
|
|
