AP Biology Check Unit 8: Behaviors

Which of the following is an example of an innate behavior in animals?

• A dog learning to sit on command

• A spider spinning a web

• A parrot mimicking human speech

• A cat using a litter box

Which behavior is considered learned rather than innate?

• A baby sea turtle moving towards the ocean

• A bird building a nest

• A chimpanzee using a stick as a tool to extract termites

• A moth flying towards light

Which of the following best explains a fixed action pattern?

• A behavior that is modified by experience

• A sequence of unlearned acts directly linked to a sign stimulus and carried out to completion

• A behavior that is learned through observation and based on a sign stimulus

• A behavior that is influenced by environmental factors and carried out to completion

Which of the following below correctly identifies the proximate cause of a bird singing in the morning?

• Increased light and temperature in the morning.
• Birds singing due to increased humidity.
• Birds singing to mark territory.
• Birds singing to attract mates.

Which type of taxis is demonstrated by a moth flying towards a light source?

• Geotaxis

• Chemotaxis

• Phototaxis

• Thermotaxis

Evaluate the effectiveness of innate behaviors in animals living in rapidly changing environments.

• Innate behaviors are highly adaptable and beneficial

• Innate behaviors may be less effective due to lack of flexibility

• Innate behaviors are always advantageous regardless of environment

• Innate behaviors are irrelevant in changing environments

Analyze the relationship between fixed action patterns and sign stimuli.

• Fixed action patterns are learned responses to sign stimuli

• Sign stimuli trigger fixed action patterns, which are innate

• Fixed action patterns are voluntary responses to sign stimuli

• Sign stimuli are irrelevant to fixed action patterns

Apply your understanding of taxis to determine which type of taxis a salmon uses to return to its birthplace.

• Phototaxis

• Geotaxis

• Chemotaxis

• Thermotaxis

Which of the following describes the difference between kinesis & taxis?

• Kinesis is a type of taxis; taxis is a type of kinesis.
• Kinesis involves movement towards a stimulus; taxis involves random movement.
• Kinesis is a response to light; taxis is a response to temperature.
• Kinesis is non-directional movement in response to a stimuli; taxis is directional movement towards or away from the stimuli.

Which example below shows a plant displaying photoperiodism?

• Ferns growing in shaded areas year-round.
• Cacti thriving in constant sunlight.
• Roses wilting in response to longer days.
• Chrysanthemums blooming in response to shorter days.
