$$Fitness = \text{Ability to produce surviving offspring}$$

Question 1

Which of the following best describes the concept of 'behavior' in animals?

Accepted Answer

A response to a stimulus that can be either innate or learned.

Question 2

Which scenario illustrates an innate behavior?

Accepted Answer

A spider spinning a web without prior experience.

Question 3

Why might learned behaviors be favored in unpredictable environments?

Accepted Answer

Because learning allows individuals to adapt to changing conditions.

Question 4

Which type of communication would most likely be used by animals active at night?

Accepted Answer

Acoustic or olfactory signals.

Question 5

The waggle dance of honeybees is an example of:

Accepted Answer

Visual communication that conveys information about food location.

Question 6

Which of the following is an example of taxis?

Accepted Answer

A moth flying toward a light source (phototaxis).

Question 7

True navigation in animals refers to:

Accepted Answer

The ability to locate a specific place on Earth's surface.

Question 8

Which of the following best explains why innate behaviors are adaptive in some situations?

Accepted Answer

Innate behaviors are favored when mistakes would be costly, such as predator avoidance.

Question 9

Kin selection is best defined as:

Accepted Answer

Natural selection that increases fitness by benefiting close relatives who share many of the same genes.

Question 10

Which equation best represents the concept of fitness in evolutionary biology?

Accepted Answer

$$Fitness = 	ext{Ability to produce surviving offspring}$$

Question 11

Which feeding strategy is most likely to increase an individual's ability to capture food in a group?

Accepted Answer

Cooperative feeding.

Question 12

A group of fish swimming together to confuse predators is an example of which evolutionary cause of behavior?

Accepted Answer

Avoiding predation by associating in groups.

Question 13

Which of the following is NOT considered social behavior?

Accepted Answer

Aggregation due to environmental factors without interaction.

Question 14

Which form of communication is most adaptive for ants and termites living underground?

Accepted Answer

Olfactory and tactile signals.

Question 15

Which of the following best describes imprinting?

Accepted Answer

A learned behavior that occurs during a rapid, irreversible critical period.

Question 16

Which scenario demonstrates classical conditioning?

Accepted Answer

A dog salivating when it hears a bell that has been repeatedly paired with food.

Question 17

Which of the following is a multi-step example of behavior increasing fitness?

Accepted Answer

A bird sings to attract a mate, then builds a nest to protect its offspring.

Question 18

Territoriality is adaptive because:

Accepted Answer

It allows individuals to defend resources necessary for survival.

Question 19

Which of the following is a plausible null hypothesis for an experiment testing tool use in crows?

Accepted Answer

Crows cannot use tools to obtain food.

Question 20

Which equation best represents the relationship between behavior and fitness?

Accepted Answer

$$Fitness = 	ext{Survival rate} + 	ext{Reproduction rate}$$
