Physical adaptation

Camouflage (use of color in a surrounding)

The chameleon can change its color to match its surroundings. Can you do that?

The Viceroy butterfly uses mimicry to look like the Monarch butterfly. Can you tell them apart?

Poisonous

Not poisonous

Physical adaptations Mimicry (looking or sounding like another living

organism)

I’m the Monarch!

I’m the Viceroy!

Chemical defenses (like venom, ink, sprays)

Physical adaptation

Body coverings & parts (claws, beaks, feet, armor plates, skulls, teeth)

Physical adaptations

The elephant’s trunk is a physical adaptation that helps it to clean itself, eat, drink, and to pick

things up.

Homeostasis

• Maintenance of constant internal conditions in the face of a varying external environment.

• Examples: – The thickening of fur in winter.– The seeking of shade in heat.– The production of more red blood

cells at high altitude.

Mr. Krabbs wants to make Bikini Bottoms a nicer place to live. He has created a new sauce that he thinks will reduce the production of body gas associated with eating crabby patties from the Krusty Krab. He recruits 100 customers with a history of gas problems. He has 50 of them (Group A) eat crabby patties with the new sauce. The other 50 (Group B) eat crabby patties with sauce that looks just like new sauce but is really just mixture of mayonnaise and food coloring.

Alex placed a small beaker of cold water on a hot plate and heated it for 10 minutes. He took the temperature of the water several times during those 10 minutes and recorded his data. Alex claims that the graph below shows the relationship between temperature and time when water is heated.

Which statement best explains why the temperature leveled off in section 2 of the graph?

A Alex turned off the hot plate so the water did not get any warmer. B The water reached the boiling point, so the temperature no longer increased.

C An experimental error caused the graph to level off, because the water temperature should keep increasing over time.

D Cold water heats faster than warm water, so once the cold water was room temperature, it took more than 10 minutes to make it hot. Click on screen to continue

Correct Final Jeopardy Response is

B The water reached the boiling point, so the temperature no longer

increased.
