Unit 1

Front 1

- How do you know if an organism is an animal?

~ What are the characteristics a scientist should look for??

Back 1

- is a multicellular organism

- capable of locomotion at some stage in its life

- is a heterotroph (feeds on other organism for energy)

- is responsive

- no cell wall

~ Scientists look for size, color, shape, & texture

Front 2

- What is the difference between an invertebrate and a vertebrate?

Back 2

- Invertebrates are animals without a backbone and vertebrates are animals with a backbone.

Front 3

~ Give an example of an animal that fits in each of these invertebrate categories: poriferans, cnidarians, mollusks, annelids, arthropods, platyhelminthes, & echinoderms.

Back 3

~ Poriferans: sponges

~ Cnidarians: jellies

~ Mollusks: squid

~ Annelids: earthworms

~ Arthropods: insects

~ Platyhelminthes: flat worms

~ Echinoderms: sea urchin

Front 4

- What is the difference between an endotherm and an ectotherm?

Back 4

- Endotherm: "cold-blooded" same temperature as outside environment

- Ectotherm: "warm-blooded" temperature on inside is always the same

Front 5

- What do fish and amphibians have in common?

(Hint: always include reproduction amongst other characteristics)

Back 5

- External fertilization

- Cloaka

- Gills

Front 6

What do amphibians and reptiles have in common?

(Hint: always include reproduction amongst other characteristics)

Back 6

- Lay eggs

- Cloaka

Front 7

Birds are classified in the reptile group.

- What characteristics cause biologists to put them in this class?

(Hint: always include reproduction amongst other characteristics)

Back 7

- They lay eggs with shells (amniotic eggs)

- Internal fertilization

Front 8

- What makes reptiles different from mammals?

(Hint: always include reproduction amongst other characteristics)

Back 8

- Reptiles have eggs with shells and a cloaka

- Mammals have hair and mammary glands

Front 9

- What is ethology?

Back 9

- The study of animal behavior under natural conditions.

Front 10

- What are two purposes of all animal behavior?

Back 10

- To survive

- Reproduce

Front 11

- What is the difference between proximate causes of behavior and ultimate causes of behavior?

Back 11

- Proximate causes: How; to explain

- Ultimate causes: Why; benefits

Front 12

- Give an example of a proximate cause question and an ultimate cause question.

Back 12

- Proximate cause:

How does an animal’s behavior change during its

growth and development, especially in response to experiences that it has while maturing?

- Ultimate cause:

How does an animal’s behavior compare with that of other closely related species, and what does this tell us about the origins of its behavior and the changes that have occurred during the history of the species?

Front 13

- What is an adaptation?

~ Can behavior be an adaptation?? Please give an example if so.

Back 13

- Changes in population that occur because of random mutations and sexual recombonation of genes.

~ Behavior can be an adaptation.

ex: elk bugling

Front 14

- What is fitness?

~ Give an example of an animal that is fit for its environment and why it is fit for that environment.

Back 14

- The ability of an organism to survive to reproductive age in a particular environment and produce viable offspring.

~ Frogs live in damp areas so that while reproducing externally, eggs will survive.

Front 15

- What are the principles of natural selection?

Back 15

- Struggle for existence

-More individuals born than there are resources

Front 16

- How do adaptations evolve?
~ Describe how whales evolved from a land ancestor.

Back 16

- Apart of the DNA mutates

~ Whale legs became fins
