The smallest unit of an element that retains its chemical properties.

The smallest unit of an element that retains its chemical properties is an atom. Each element is made up of one type of atom, which contains a unique number of protons in its nucleus, determining its chemical properties. Atoms combine to form molecules through chemical bonding, but the individual characteristics of an element are defined by its atoms.

The central part of an atom, composed of protons and neutrons.

The central part of an atom is called the nucleus, and it consists of protons and neutrons.

A substance that cannot be broken down into simpler substances by chemical means.

An element is a substance that cannot be broken down into simpler substances by chemical means, as it consists of only one type of atom with a unique number of protons in its nucleus. Elements form the foundation of all matter and are depicted on the periodic table, each with its own distinct properties and characteristics.

A substance made up of two or more elements chemically combined.

A compound is a substance composed of two or more elements that are chemically bonded together in fixed proportions.

The force that attracts two objects towards each other.

The force that attracts two objects towards each other is called gravitational force. This force is proportional to the mass of the objects and inversely proportional to the square of the distance between them, as described by Newton's law of universal gravitation.

The process by which an organism produces its offspring.

Reproduction is the process by which an organism produces its offspring through sexual or asexual means. During reproduction, genetic material is passed on from parent to offspring, ensuring the continuation of the species. This vital process is essential for the survival and evolution of living organisms.

The process of converting light energy into chemical energy in plants.

The process of converting light energy into chemical energy in plants is called photosynthesis. During this process, plants use light, carbon dioxide, and water to produce glucose (sugar) and oxygen. Photosynthesis is a crucial biological process that provides energy for plants to grow and carry out their functions, while also releasing oxygen into the atmosphere as a byproduct.

The study of living organisms and their interactions with each other and their environment.

The study of living organisms and their interactions with each other and their environment is known as ecology.

A change in the frequency of a wave due to the motion of the source or observer.

A unit of measurement for electric current.

An ampere, often denoted as amp, is a unit of measurement for electric current. It is the rate of flow of electric charge in a circuit and is used to quantify the amount of electric current passing through a point in the circuit at a specific time.
