b.	there is strength in numbers	
c.	herds can hide more easily than individuals	

 	7.	What is a benefit of thigmotropism in plants?
a.	the plant is able to support itself as it grows taller	
b.	roots of a germinating seed are able to grow down into the soil	
c.	the plant is able to find a source of water	

 	8.	What is a benefit of phototropism in plants?
a.	allows the fruit of the plant to ripen more quickly	
b.	gives the leaves the sunlight they need for photosynthesis	
c.	causes the roots to grow deeper into the soil	

 	9.	The Hawk Moth, shown above, has a special coloration pattern.  What is the purpose of this pattern?
a.	to blend in with its surroundings	c.	to scare away predators	
b.	to help it survive a harsh winter

 	10.	Many plants lose their leaves in the fall only to grow them back in the spring.  How is this adaptation helpful for the plant?
a.	it allows insects to pollinate the plant’s flowers and produce seeds	
b.	photosynthesis can happen more quickly when there are no leaves on the plant	
c.	the plant saves its resources by not trying to survive in harsh weather	

 	11.	Why do many fish have a bold stripe across their eyes?

a.	hibernation.	b.	estivation.	c.	migration.	

 	14.	Vines in the rainforest typically grow up the trunks of the tall trees by attaching to the bark or wrapping around branches.  This is an example of 
a.	phototropism.	b.	gravitropism.	c.	thigmotropism.			

 	15.	The adaptation shown by the owl in the image above is
a.	aposematic coloration.	c.	disruptive coloration.	
b.	cryptic coloration.			

 	16.	Many plants have colorful flowers and sweet nectar.  Why is this important for the plant?
a.	It kills the plant because the flower gets destroyed by the organisms that are attracted to it.	
b.	It allows the seeds of the plant to be distributed far away from the parents, which reduces competition.	
c.	It will attract pollinators, which are necessary for the plant to be able to get the pollen needed for reproduction.	

 	17.	The male peacock has very brightly colored feathers that it displays when fanning out its tail.  The feathers can be quite large and make it difficult for the male to move around.  Why does this trait exist if it makes life more difficult to the organism?
a.	it allows the male peacock to attract a mate and produce offspring	
b.	it helps the male peacock catch its prey	
c.	large feathers require less energy to make and maintain, so the male peacock won’t need to consume as much food	

 	18.	The display pattern and behavior of the male peacock is an example of
a.	warning coloration	b.	metamorphosis	c.	courtship			

 	19.	The life cycle of a beetle is shown to the right.  As the organism grows into adulthood, it goes through several different body forms.  This is called
a.	courtship.	b.	metamorphosis.	c.	tropism.
