1.
Behaviour can be so well adapted to an animal’s way of life that it simply knows what to do and when to do it.
Correct Answer
A. True
Explanation
Animals can exhibit behavior that is instinctual and well-adapted to their specific way of life. This means that they inherently know what actions to take and when to take them, without needing to learn or be taught. This innate knowledge allows them to survive and thrive in their environment. Therefore, the statement that behavior can be so well adapted to an animal's way of life that it simply knows what to do and when to do it is true.
2.
A concise definition of communication is the responding of one animal to the signals sent by another animal.
Correct Answer
A. True
Explanation
The given statement is true because communication involves the exchange of signals between animals. It is a process where one animal sends signals, such as vocalizations or body movements, and another animal responds to those signals. This exchange of signals allows animals to convey information, express emotions, establish social bonds, and coordinate their behaviors. Communication is an essential aspect of animal behavior and plays a crucial role in their survival and reproduction.
3.
The most common form of visual communication is through facial expression.
Correct Answer
B. False
Explanation
Facial expression is indeed a form of visual communication, but it is not the most common form. Other forms of visual communication, such as body language, gestures, and symbols, are also widely used. Therefore, the statement that the most common form of visual communication is through facial expression is false.
4.
Vocal communication is necessary for many tasks, including mating rituals, warning calls, conveying location of food sources, and social learning.
Correct Answer
A. True
Explanation
Vocal communication plays a crucial role in various tasks such as mating rituals, warning calls, conveying the location of food sources, and social learning. These tasks require animals to communicate with each other using vocalizations to attract mates, alert others of potential dangers, share information about food sources, and learn from others in their social group. Therefore, it is true that vocal communication is necessary for these tasks.
5.
Touch can be very important in certain social interactions, and grooming of one animal by another is perhaps the most obvious and widespread touch behaviour.
Correct Answer
A. True
Explanation
This statement suggests that touch is an important aspect of social interactions, and one common form of touch behavior is grooming between animals. This implies that touch plays a significant role in their social dynamics and relationships. Therefore, the statement is true.
6.
The importance and sensitivity of smell varies among different organisms; most birds have a good sense of smell, whereas most mammals do not.
Correct Answer
B. False
Explanation
Most mammals actually have a good sense of smell. This is because the olfactory system in mammals is highly developed, allowing them to detect and distinguish a wide range of scents. In contrast, birds rely more on their vision and hearing, and their sense of smell is generally not as well-developed. Therefore, the statement that most mammals do not have a good sense of smell is false.
7.
A common form of animal communication is electrocommunication.
Correct Answer
B. False
Explanation
Electrocommunication is not a common form of animal communication. While some species, such as electric fish, use electrical signals for communication, it is not a widespread form of communication among animals. Most animals rely on other forms of communication, such as vocalizations, visual displays, or chemical signals, to communicate with each other. Therefore, the statement that electrocommunication is a common form of animal communication is false.
8.
Visual communication includes morphological colour change, in which changes occur in relation to stage of development, or physiological colour change, in which colour change is triggered by mood, social context, or factors such as temperature.
Correct Answer
B. False
Explanation
The explanation for the correct answer, which is False, is that visual communication includes morphological color change and physiological color change. Morphological color change refers to changes in color that occur in relation to the stage of development, while physiological color change refers to changes triggered by factors such as mood, social context, or temperature. Therefore, visual communication does include both types of color change.
9.
Rutting season is the mating season of ruminant mammals.
Correct Answer
A. True
Explanation
Rutting season refers to the period when ruminant mammals engage in mating activities. This includes species such as deer, elk, and moose. During this season, male ruminants become more aggressive and territorial as they compete for mates. They also exhibit behaviors such as making loud vocalizations, marking their territory, and engaging in physical fights with other males. Therefore, it is true that rutting season is the mating season of ruminant mammals.
