What does the word "adapt" mean?
Correct Answer
B. Change
Explanation
The word "adapt" means to change or adjust. It refers to the ability to modify oneself or one's behavior in order to fit new circumstances or conditions. This can involve making alterations or modifications to better suit a particular situation.
2.
Which of the following is a physical adaptation?
Correct Answer
A. Sharks have fins to help them swim
Explanation
The correct answer is "sharks have fins to help them swim." This is a physical adaptation because fins are a physical feature that helps sharks navigate and move efficiently through water. Fins provide stability, balance, and propulsion, allowing sharks to swim and hunt effectively. This adaptation is specific to sharks and enables them to survive and thrive in their aquatic environment.
3.
What does instinct mean?
Correct Answer(s)
C. Behavior that an organism inherits
D. Behaviors learned from their friends
Explanation
Instinct refers to behavior that an organism inherits and behaviors learned from their friends. Instinctive behavior is innate and does not require any prior learning or experience. It is genetically programmed and is common across individuals of the same species. On the other hand, behaviors learned from friends are acquired through social interactions and observation of others. These behaviors are not innate but are acquired through social learning and can vary between individuals and groups.
4.
What are learned behaviors?
Correct Answer
D. Behaviors learned from their parents
Explanation
Learned behaviors refer to actions or responses that an organism acquires through experience or observation. These behaviors are not inherited but rather acquired from the parents or other individuals in the environment. This includes skills, knowledge, and habits that are passed down through generations or acquired through social interactions.
5.
What happens when animal do not "fit in" with their surroundings?
Correct Answer
A. They die
Explanation
When animals do not "fit in" with their surroundings, they are unable to adapt to their environment effectively. This lack of adaptation can lead to difficulties in finding food, shelter, or avoiding predators. As a result, these animals may not be able to survive and eventually die.
6.
What is one example of how animals adapt in their environment in order to survive?
Correct Answer
D. All of the above
Explanation
Animals adapt in various ways to survive in their environment. One example is hibernation, where animals enter a state of dormancy during harsh conditions to conserve energy and survive through the scarcity of resources. Migration is another adaptation, where animals move from one region to another in search of better resources or to avoid unfavorable conditions. Lastly, animals use camouflage to blend into their surroundings, which helps them hide from predators or ambush prey. All of these adaptations are examples of how animals adjust to their environment to increase their chances of survival.
7.
Why do animals eat a lot before hibernating?
Correct Answer
B. To build up a layer of fat
Explanation
Animals eat a lot before hibernating to build up a layer of fat. This fat serves as a source of energy during the long period of hibernation when the animals are not actively feeding. By consuming a large amount of food and storing it as fat, animals ensure that they have enough energy reserves to sustain themselves throughout the hibernation period when food is scarce.
8.
What is camouflage?
Correct Answer
A. The ability to blend in with your environment
Explanation
Camouflage refers to the ability of an organism to blend in with its surroundings. This adaptation allows the organism to go unnoticed by predators or prey, increasing its chances of survival. Camouflage can take various forms, such as coloration, patterns, or behaviors that mimic the environment. By blending in, the organism becomes harder to detect, making it easier to hunt or avoid being hunted. This adaptation is commonly observed in animals, but it can also be seen in plants and even military strategies.
9.
Which of the following is not a reason some animals use camouflage?
Correct Answer
B. To play hunting games with members of their own species
Explanation
Some animals use camouflage to get food by blending in with their surroundings and ambushing their prey. They also use camouflage to keep from becoming food themselves, as it helps them hide from predators. However, playing hunting games with members of their own species is not a reason for animals to use camouflage. Camouflage is primarily used for survival purposes, such as obtaining food or avoiding becoming prey.
10.
What is migration?
Correct Answer
A. The instinctive movement of a group of animals
Explanation
Migration refers to the instinctive movement of a group of animals from one place to another. This movement is usually seasonal and is driven by factors such as changes in weather, availability of food, or the need for breeding grounds. During migration, animals travel long distances to reach their destination, often following specific routes or landmarks. This behavior is essential for their survival and is observed in various species, including birds, mammals, and fish.
11.
What is symbosis?
Correct Answer
A. Life together
Explanation
Symbiosis refers to a close and long-term interaction between two different species, where both species benefit from the relationship. It involves living together in a mutually beneficial manner, such as through mutualism, where both species benefit, or through commensalism, where one species benefits while the other remains unaffected. This term encompasses various types of relationships, including mutual dependence, cooperation, and interdependence, highlighting the concept of "life together" between different organisms.
12.
What are the three types of symbiotic relationships?
Correct Answer
D. Mutualism, commensalism, and parasitism
Explanation
The correct answer is mutualism, commensalism, and parasitism. These three types of symbiotic relationships describe different interactions between two species. Mutualism is a relationship where both species benefit. Commensalism is a relationship where one species benefits while the other is unaffected. Parasitism is a relationship where one species benefits at the expense of the other. These three types of relationships are important in understanding the dynamics of ecosystems and the interactions between different organisms.
13.
What is commensalism?
Correct Answer
B. Good for me, doesn't bother you
Explanation
Commensalism is a type of symbiotic relationship where one organism benefits while the other is neither harmed nor benefited. In this case, the answer "good for me, doesn't bother you" accurately describes commensalism as it implies that one organism benefits without causing any harm or benefit to the other organism.
14.
What is parasitism?
Correct Answer
A. Good for me, bad for you
Explanation
Parasitism is a type of symbiotic relationship where one organism benefits (good for me) at the expense of another organism (bad for you). In this relationship, the parasite benefits by obtaining nutrients or shelter from the host, while the host is harmed or negatively affected.
15.
What is mutualism?
Correct Answer
C. Good for me, good for you
Explanation
Mutualism refers to a symbiotic relationship where both parties involved benefit from the interaction. In this case, the correct answer "good for me, good for you" indicates that both individuals involved in the mutualistic relationship experience positive outcomes. This type of relationship is characterized by cooperation and reciprocity, where both parties gain advantages or resources that contribute to their well-being.
16.
How does a crocodile benefit from a bird eating form its mouth?
Correct Answer
A. It gets clean teeth
Explanation
Crocodiles benefit from a bird eating from their mouth because it helps to clean their teeth. As the bird pecks at the crocodile's teeth, it removes food particles and debris, acting as a natural toothbrush. This cleaning action helps to maintain the crocodile's dental hygiene and prevent the buildup of bacteria and potential infections.
17.
Give an example of parasitism.
18.
What is natural selection?
Correct Answer
C. The survival of the fittest
Explanation
Natural selection is the process by which certain traits or characteristics become more or less common in a population over time. It is based on the idea that individuals with advantageous traits are more likely to survive and reproduce, passing on those traits to future generations. The phrase "the survival of the fittest" encapsulates this concept, as it refers to the idea that individuals who are best adapted to their environment are more likely to survive and pass on their genes.
19.
How does natural selection work?
Correct Answer
A. Those who are best adapted to their environment survive and reproduce
Explanation
Natural selection is the process by which individuals with advantageous traits that are well-suited to their environment are more likely to survive and reproduce. This leads to the passing on of these favorable traits to future generations. The concept of "survival of the fittest" is closely related to natural selection, as those organisms that are best adapted to their environment are more likely to survive and pass on their genes. The size or intelligence of an animal does not necessarily determine their ability to adapt to their environment, so the correct answer is that those who are best adapted to their environment survive and reproduce.
