Question 1

Which of the following best describes the function of a reflex arc in animal behavior?

Accepted Answer

It is a simple neural pathway that enables rapid, automatic responses to stimuli.

Question 2

In the experiment with wingless cockroaches, what type of behavior is being investigated when testing their response to light and humidity?

Accepted Answer

Innate behavior

Question 3

Which of the following is a likely adaptive value of fish schooling behavior?

Accepted Answer

It enhances protection from predators through group vigilance.

Question 4

A student performs a Chi-square test to analyze fish schooling behavior. If the calculated $$\$$chi^2$$ value is 5.2 and the critical value at p = 0.05$ is 3.84, what is the correct interpretation?

Accepted Answer

The null hypothesis is rejected; there is a significant difference.

Question 5

Which formula is used to calculate the Chi-square ($$\$$chi^2$$) statistic in behavioral experiments?

Accepted Answer

$$\$$chi^2$$ = \sum \frac{(O-E)^2$}{E}$$

Question 6

In the cockroach experiment, if most cockroaches are found on the dark and humid side, what can be inferred about their habitat preference?

Accepted Answer

Cockroaches prefer humid and dark environments.

Question 7

Which of the following is NOT a step in the reflex arc mechanism as described in the study materials?

Accepted Answer

Brain processes the impulse before any response occurs.

Question 8

During the fish schooling experiment, what is the purpose of using a positive stimulus in the beaker?

Accepted Answer

To test if fish are attracted to the stimulus and prefer to school near it.

Question 9

Which behavioral objective is achieved by observing the habituation of planaria?

Accepted Answer

Understanding how repeated exposure to a stimulus reduces response.

Question 10

If the observed frequency of fish on the side with stimulus is 15 and the expected frequency is 10, what is the $$\$$chi^2$$ value for this observation?

Accepted Answer

$$\$$chi^2$$ = \frac{(15-10)^2$}{10} = 2.5$$

Question 11

Which of the following best explains why habituation is considered an adaptive behavior?

Accepted Answer

It allows organisms to ignore irrelevant stimuli and focus on important changes.

Question 12

In the context of animal behavior, which statement about innate and learned behaviors is correct?

Accepted Answer

Innate behaviors are genetically programmed and do not require experience.

Question 13

Which experimental setup is used to test the effect of light on wingless cockroach movement?

Accepted Answer

A chamber divided into light and dark sections with cockroaches placed in the center.

Question 14

What is the main reason for using the Chi-square test in animal behavior experiments?

Accepted Answer

To determine if observed frequencies differ significantly from expected frequencies.

Question 15

Which of the following is a correct interpretation if the calculated $$\$$chi^2$$ value is less than the critical value at p = 0.05$?

Accepted Answer

There is no significant difference; the null hypothesis is accepted.

Question 16

In the planaria habituation experiment, what would you expect to observe after repeated exposure to the same stimulus?

Accepted Answer

A decrease in the behavioral response over time.

Question 17

Which of the following is a real-world application of understanding animal behavior in cockroaches?

Accepted Answer

Designing effective pest control strategies based on habitat preferences.

Question 18

In the fish schooling experiment, what is the expected outcome if the positive stimulus is effective?

Accepted Answer

Fish will spend more time on the side with the stimulus.

Question 19

Which of the following best describes the difference between 'superstimulated' and 'unsuperstimulated' planaria in the experiment?

Accepted Answer

Superstimulated planaria show a stronger behavioral response to the stimulus.

Question 20

Which of the following is NOT a behavioral objective listed in the study materials?

Accepted Answer

Measure the oxygen consumption of fish during schooling.
