What is the difference between a vertebrate and an invertebrate?
The difference between a vertebrate and an invertebrate is that a vertebrate has a skull and backbone and an invertebrate does not.
3. Give three examples of vertebrates: Monkey Elephant Fish Snakes Human Reptiles Birds All Mammals would be correct examples
4. Give three examples of invertebrates: Jellyfish Sponge Starfish Octopus Clam Worms Arthropods (Insects, spiders, ticks,
lobster, butterfly)
5. Usually reproduce by sexual reproduction: An egg cell is fertilized by a sperm cell
to make a new organism
5. Develop from embryos: Stems from fertilized cell An embryo is an organism in it’s earliest
stage of development
5. Have many specialized parts: Each animal has unique parts to it that
serve as different functions Tissues-collection of similar cells- Ex:
muscle tissue, nerve tissue Organs-Two or more tissues make an
organ. Ex: heart, lungs, brain
6. What is the difference between innate and learned behavior? Innate: behavior that you can do but no
one had to teach you
Learned: behavior that you had to be taught or learned by observation
7. Give two examples of innate behavior and two examples of learned behavior. Innate: a baby crying after birth, a dog
walking, ability for speech, whale swimming, breathing, blinking, eating
Learned: a person speaking English, a monkey cleaning its food, how to be polite, a human swimming
8. How do animals survive during their period of hibernating and estivating? Lower body temperature Lower heart rate Lower breathing rate Lives off of stored body fat
9. What is the difference between hibernation and estivation? Hibernation: during the winter
Estivation: during the summer
How do you restate the question to make a complete sentence?
The difference between hibernation and estivation is that hibernation is in the winter and estivation is in the summer.
10. What are reasons why animals hibernate and estivate?
Food shortages
Water shortages
Extreme temperatures (either too hot or too cold)
11. What is a biological clock? An internal cycle over a longer period of
time that tells animals when to migrate, hibernate, or estivate
12. What do animals do when their seasonal biological clock tells them the seasons are changing? Migrate Hibernate Estivate
13. What are signs in the environment that tell an animal their biological clock needs to kick in? Daylight-days getting shorter or longer Leaves changing Temperature changes
15. Give three different examples that show what a MONKEY’s circadian rhythm is telling it. Wake up 7:00am Hungry- eats breakfast 7:30am Daytime nap 8:00-3:00 Wake up from nap 3:00 Hungry-eats snack 3:15
16. Explain how animals navigate.
Landmarks Sun & Stars Magnetic Field
Animals use landmarks such as streams, rivers, mountains, coast lines, specific trees, etc. to find their way from one place to another.
Using the sun, moon and stars animals can see which direction they are traveling.
Some animals, such as migratory birds, have a magnet above their nostril in order to tell them which direction they are heading using the Earth’s magnetic pull.
Smell
They will mark their territory in order to find their way back to certain places
17. These are the four types of communication. Give an example of each type.
Smell Sound Vision Touch
Ants use pheromones to find their way home
Communicate to find food or warn others
Speak
Knocking on door
Crickets chirp
Humans use body
language to show
expression; courtship displays
Hugs to show you
care
Tap gets your
attention
Bees waggle dance
18. List the advantages and disadvantages of living in groups.
Advantages Disadvantages
• Defend territory• Help find food• Easier for mating• Safety in numbers
• Spread diseases• Fighting• Attract predators• Need more food
