Genetic material is crucial in inheritance because it carries the instructions for an organism’s traits and characteristics. It ensures that these traits are passed from parents to offspring, maintaining continuity of species.

Living organisms use energy, primarily from food or sunlight, to fuel metabolic processes, maintain homeostasis, and support growth and reproduction. Energy is essential for performing various physiological functions and sustaining life.
Sexual reproduction involves two parents and the combination of genetic material, resulting in genetic diversity. Asexual reproduction involves one parent and produces genetically identical offspring, typically through methods like fission, budding, or vegetative propagation.
Living creatures respond to internal stimuli, like hunger or pain, and external stimuli, like temperature or light. Responses involve behavioral changes or physiological adjustments to maintain homeostasis and ensure survival.
The mantle is responsible for secreting the shell in snails. It produces calcium carbonate, which forms the shell’s layers, and continuously adds material to accommodate the snail’s growth and provide protection.
Living organisms adapt to environmental changes through behavioral adjustments, physiological changes, or evolutionary processes. These adaptations help them survive by optimizing their responses to new conditions and challenges.
Cellular differentiation is significant because it allows cells to develop specialized functions and structures. This process is crucial for forming tissues and organs, enabling complex organisms to perform diverse and specific functions.
Feedback systems regulate temperature by detecting deviations from the set point and initiating responses. For instance, sweating cools the body when it’s too hot, while shivering generates heat when it’s too cold.
Examples of asexual reproduction include binary fission in bacteria, budding in yeast and hydras, and vegetative propagation in plants like strawberries and potatoes. These methods allow organisms to reproduce without a mate.
Maintaining homeostasis is crucial for living creatures because it ensures that internal conditions remain stable and optimal for physiological processes. This stability is essential for survival, allowing organisms to function effectively despite external changes.
