علم الأحياء
the scientific study of living organisms; the science that studies living organisms
Biology is the study of living organisms, including their structure, function, growth, and interactions with their environment. It covers a wide range of topics, from the molecular mechanisms within cells to the behavior of entire ecosystems. Biology helps us understand the diversity of life on Earth, how organisms adapt to their surroundings, and the processes that sustain life, such as metabolism, reproduction, and evolution.

الأيض
the chemical processes through which food is changed into energy for the body to use
Metabolism refers to the complex set of biochemical processes that occur within cells to convert nutrients into energy and essential molecules for growth, repair, and maintenance. It encompasses both the breakdown of substances (catabolism) to release energy and the synthesis of molecules (anabolism) to build and maintain cellular structures. Metabolism influences the body's energy expenditure, regulation of body weight, hormone production, and overall physiological functioning. It is regulated by various factors, including genetics, age, diet, physical activity, and hormonal balance. Metabolism is a vital process that supports the body's basic functions and is closely linked to overall health and well-being.

(علم الكيمياء)
كيمياء
the branch of science that is concerned with studying the structure of substances and the way that they change or combine with each other
Chemistry is the scientific study of the composition, properties, and reactions of matter. Chemists explore how substances interact with one another, form new compounds, and undergo transformations. Chemistry is fundamental in fields like medicine, environmental science, and industry, as it helps create new materials, understand biological processes, and develop products from energy to pharmaceuticals.

(biochemistry) a chemical substance that carries the genetic information, which is present in every cell and some viruses
Deoxyribonucleic acid (DNA) is a molecule that contains the genetic instructions for the development, functioning, and reproduction of all living organisms. DNA is made of two long, twisted strands that form a spiral shape, and it carries the hereditary information used to build and maintain an organism. Each segment of DNA, called a gene, provides instructions for making specific proteins that influence traits and manage various bodily functions. DNA is found in the cells of all living things and is passed from parents to children, directing growth and development.

(genetics) a basic unit of heredity and a sequence of nucleotides in DNA that is located on a chromosome in a cell and controls a particular quality
A gene is a segment of DNA that provides the instructions for making proteins, which are essential for the body's growth, development, and overall functioning. Genes influence traits such as eye color, blood type, and the likelihood of developing certain diseases. They are passed from parents to children and can affect how the body responds to environmental factors and treatments.

(ليف)
ألياف
any strand of muscle or nervous tissues
In the nervous system, fiber refers to the long, thin extensions of neurons that transmit electrical impulses to other neurons or to muscles and glands. These fibers, also called axons, are covered in a protective sheath called myelin, which helps to speed up the transmission of impulses. The myelin sheath is produced by specialized cells called oligodendrocytes in the central nervous system and Schwann cells in the peripheral nervous system. Damage to the myelin sheath, such as in the case of multiple sclerosis, can cause disruptions in nerve impulse transmission and lead to a range of neurological symptoms, including muscle weakness, numbness, and vision problems.
