Test: Variety of Organisms - 2 - JAMB MCQ

Structural adaptations in organisms are physical traits that enhance their survival in a particular habitat. These adaptations can include features like specialized body parts, protective coverings, or mechanisms for obtaining food. They are not related to changes in behavior, genetic variations, or metabolic modifications.

Functional adaptation refers to adaptations that involve the internal physiological processes or functions of an organism. Camouflage of chameleons to blend with their surroundings is an example of functional adaptation as it helps them hide from predators by changing their skin color. Migration, hibernation, and skin shedding are examples of other types of adaptations.

Adaptive coloration in organisms primarily serves the function of deterring predators through warning signals. For example, bright color patterns in certain animals indicate that they may be toxic or dangerous to predators. While attracting mates, efficient locomotion, and photosynthesis are important functions for organisms, they are not directly associated with adaptive coloration.

The formation of complex social hierarchies is a behavioral adaptation commonly observed in social animals. It involves the organization of individuals within a group or society based on dominance, roles, and interactions. Development of sharp claws, production of venom, and the ability to regenerate lost body parts are examples of other types of adaptations.

A lioness hunting in a group is an example of behavioral adaptation. Lions exhibit cooperative hunting behaviors, where individuals work together to increase their chances of capturing prey. This behavior enhances their hunting success and is a characteristic adaptation of social animals. Structural adaptation relates to physical traits, functional adaptation relates to internal processes, and physiological adaptation refers to adaptations at the cellular or molecular level.

The presence of spines on a cactus is an example of structural adaptation. The spines help protect the cactus from herbivores by deterring them from feeding on the plant. Structural adaptations are physical features or characteristics that organisms possess to survive and thrive in their environment. Functional adaptations, on the other hand, involve internal physiological processes, while behavioral adaptations are related to the actions and behaviors of organisms.

A polar bear's white fur in snowy regions is an example of adaptive coloration. The white fur helps the polar bear blend in with its snowy environment, providing camouflage and making it less visible to potential prey and predators. Adaptive coloration refers to the color patterns and pigmentation that help organisms survive in their specific habitats. The other options mentioned are not directly related to adaptive coloration.

Structural adaptations in organisms are primarily influenced by environmental factors. Organisms develop physical traits and features to adapt to their specific habitats and ecological conditions. While genetic factors play a role in the inheritance of these traits, environmental factors are the driving force behind the selection and development of structural adaptations. Behavioral and physiological factors are more related to other types of adaptations.

The presence of long ears for heat dissipation is a structural adaptation in animals living in hot deserts. The long ears help dissipate excess heat from the body, allowing the animal to cool down more effectively in the desert environment. Migration, development of a thick layer of blubber, and hibernation are adaptations observed in other habitats or conditions.

A chameleon changing its skin color to match its surroundings is an example of behavioral adaptation. This behavior helps the chameleon camouflage itself and blend into its environment, making it less visible to predators and allowing it to approach prey more effectively. Structural adaptations refer to physical traits, functional adaptations relate to internal processes, and physiological adaptations pertain to cellular or molecular adaptations.
