Understanding light is crucial in optics and various scientific applications.
• Sound:- In physics, sound is a mechanical wave that propagates through a medium, typically air, by compressing and rarefying particles. It requires a source, a medium, and a receiver for transmission. Sound waves exhibit characteristics like frequency and amplitude, contributing to the perception of pitch and volume in auditory experiences.
• Magnetism:- Magnetism is a physical phenomenon characterized by attractive or repulsive forces between objects with magnetic properties. It arises from the alignment of atomic or molecular magnetic moments. Materials can be classified as ferromagnetic, paramagnetic, or diamagnetic based on their response to external magnetic fields.
• Static Electricity:- Static electricity is a phenomenon resulting from an imbalance of electric charges on the surface of an object. When certain materials rub against each other, electrons transfer, leading to a buildup of charge. This static charge can cause sparks, electric shocks, and attractions or repulsions between charged objects.
• Atomic Physics:- Atomic physics is a branch of physics that explores the behavior of atoms, the smallest units of matter. It involves studying atomic structure, interactions between electrons and nuclei, and phenomena like atomic transitions. Atomic physics plays a crucial role in understanding the properties and behavior of matter at the atomic level.
• Nuclear Physics:- Nuclear physics is a field of physics that investigates the properties and behavior of atomic nuclei. It explores nuclear reactions, radioactive decay, and the structure of atomic nuclei, providing insights into fundamental forces and the dynamics of nuclear processes. This discipline plays a key role in understanding the nature of matter.
• Astronomy and Space:- Astronomy in physics is the study of celestial objects and phenomena, employing principles of physics to understand their behavior. Space, a physical expanse beyond Earth’s atmosphere, is the backdrop for astronomical observations. Together, they form a multidisciplinary field exploring the vastness of the cosmos and its underlying physical laws.

• Study of Life:- The study of life in science refers to biology, a branch of science that investigates living organisms and their interactions. It encompasses the examination of cells, genetics, ecology, and evolution, providing insights into the complexities of life. Biology plays a pivotal role in understanding the diversity, functions, and interdependence of living systems.
• Cell — The Basic Unit Of Life:- In science, a cell is the basic unit of life, representing the smallest, functional unit of living organisms. Cells can be single-celled or part of multicellular organisms. They carry out essential life processes, such as metabolism and reproduction. The study of cells is central to the field of biology.
• Classification of Living Organisms:- Classification of living organisms involves sorting and categorizing them based on shared characteristics. This hierarchical system, known as taxonomy, organizes life into domains, kingdoms, phyla, classes, orders, families, genera, and species. This systematic approach enhances understanding of biodiversity and evolutionary relationships among different organisms.
• Organisation Of The Living Body:- A multicellular organism is not a heap of cells but a highly organised body, the complexity of which increases as we proceed from simple primitive forms to the more advanced. Cells, the structural and functional units of the living body, are organised into tissues which in turn are organised into organs and organ systems. The organisation is, in fact, for the division of labour as the number of cells increases because of the increase in body size. However, the organisation is different in plants and animals since their ways of life are different.
• Nutrition:- All living organisms from bacteria to man obtain their nourishment from the atmosphere to be able to perform their activities that distinguish them from the inanimate world. The plants obtain from the atmosphere only some mineral nutrients and a few simple inorganic compounds like carbon dioxide (CO₂,) and water (H₂,0). Making use of the solar energy, the plants fix CO₂, during the process of photosynthesis to synthesize simple sugars (carbo- hydrates) that are used as a source of energy and carbon to synthesize all other biomolecules like lipids, proteins, and nucleic acids. As such, plants are not dependent on the atmosphere for their organic food (comprising carbohydrates, fats, proteins, and vitamins) and are, therefore, referred to as autotrophs (photoautotrophs). Some bacteria can also synthesize their food making use of solar energy or chemical energy of some inorganic compounds and are referred to as photoautotrophs or chemoautotrophs respectively. The animals, fungi, and most bacteria, on the other hand, are incapable of synthesizing their own food and, therefore, must obtain it from the atmosphere. All such organisms are called heterotrophs.
• Respiration:- Respiration, in the biological context, refers to the process by which living organisms exchange gases with their environment, typically involving the intake of oxygen and the release of carbon dioxide. In cellular respiration, this occurs within cells to produce energy ATP(Adenosine triphosphate) through the breakdown of organic molecules. In larger organisms, respiratory systems facilitate gas exchange, ensuring the delivery of oxygen to cells and the removal of carbon dioxide. Respiratory processes are essential for sustaining life and supporting metabolic activities.
• Circulatory System:- In human beings the transport of material take place by a fluid medium. The Blood circulates throughout the body by circulatory system and keep each body cell into a living state. The circulatory system in human beings consists of heart and blood vessels. Arteries, veins and capillaries are the types of blood vessels.
• Blood:- The blood is a body tissue and liquid in form. It consists of cells floating in the liquid medium. Blood cells are called corpuscles and liquid medium is blood plasma.
• Excretory System:- Excretion is the removal from the body of the toxic waste products of metabolism. In human beings Skin, Lungs, Liver and Kidney are the organ involved in the excretory system.

Skeleton System:- The skeleton system of the body comprises the bones and it provides a solid and rigid shape to the body. These bone are called the organs of the skeleton system. Total number of bones in the human beings is 206. A new born baby has 300 bones, out of which 94 bones fuse together as it grows.

The skeleton system of the body has been classified into seven important categories likes Skull Bones, Facial Bones, Bones of the Trunk, Bones of the Hand, Bones of the Leg etc.

Nervous System:- The nerves, the brain and the spinal cord constitute the nervous system. Nervous system controls and regulates the activities of all the other systems the body likes Brain, Cerebrum, Medula Oblongata, Spinal Cord, Sense Organs.

Major Human Endocrine Glands

Hormones:- There are special chemicals that regulates the physiological processes in animals. These chemicals are known as hormones.

Endocrine Glands:- The organs by which hormones are secreted are called endocrine glands also ductless glands. The secretion of such gland are internal and pour their secretions into the blood or lymph.

Pancreas secretes pancreatic juice.
