2. DNA and Genetic Material: Animals possess DNA (deoxyribonucleic acid) as their genetic material. DNA stores and transmits hereditary information, determining the characteristics passed from parents to offspring.
3. Metabolism: Animals exhibit metabolism, which refers to the chemical processes that occur within their bodies. These processes include the conversion of food into energy, the building and breakdown of molecules, and the removal of waste products.
4. Movement and Locomotion: Most animals have the ability to move and transport themselves from one place to another. They possess specialized structures, such as legs, wings, fins, or cilia, that facilitate their movement.
5. Reproduction: Animals reproduce to ensure the continuation of their species. Different animals have distinct reproductive strategies, including sexual reproduction (involving the union of gametes) and asexual reproduction (involving the production of offspring from a single parent).
6. Response to Stimuli: Animals have the capacity to sense and respond to various stimuli from their environment. These stimuli can range from light, sound, temperature changes, touch, and chemical signals. Their responses may involve movement, behavioral changes, or physiological adjustments.
7. Growth and Development: Animals undergo growth and development throughout their lives. They start as embryos or hatchlings and progress through various stages before reaching maturity. Growth involves an increase in size, while development refers to the differentiation and specialization of cells, tissues, and organs.
8. Adaptation: Animals have evolved and adapted to various habitats and environments over time. These adaptations can be structural, physiological, or behavioral, allowing animals to survive and thrive in different conditions.
9. Diversity: The animal kingdom exhibits tremendous diversity, encompassing a wide range of species with varying anatomical structures, life cycles, ecological roles, and behavioral patterns. This diversity is essential for the balance and functioning of ecosystems.
10. Evolution: The common characteristics shared by animals can be attributed to their evolutionary history. Animals have descended from common ancestors through processes like natural selection, where beneficial traits that enhance survival and reproduction become more prevalent over time.
