Characteristics And Diversity Among The Animals MDCAT Quiz; Characteristics and diversity among the animals are fundamental concepts in biology, emphasizing the wide variety of life forms within the animal kingdom. This topic is very important for MDCAT students since it deals with the classification, structure, and functions of animals in different species. Ace your exams with an MDCAT Quiz on animal characteristics and their diversity.
Key Characteristics of Animals
Animals share several common characteristics, such as multicellularity, heterotrophy—it means depending on other organisms for food—and mobility, at least during some stage of life. Mostly, animals have specialized tissues and organ systems with a highly developed sensory and nervous system that enables them to interact with their environment. This diversity in characteristic allows animals to adapt themselves in different ecological niches, from aquatic life forms to the terrestrial organisms. Knowledge of these basic features is very important for MDCAT students who want to master the classification and biological functions of animals.
