Neurons :
(also called neurones or nerve cells) are the fundamental units of the brain and nervous system, the cells responsible for receiving sensory input from the external world, for sending motor commands to our muscles, and for transforming and relaying the electrical signals at every step in between.
structure:
They have three distinct parts, including a cell body,axon, and dendrites. These parts help them to send and receive chemical and electrical signals
function:
neurons transmit signals throughout the body. Neurons have long extensions that extend out from the cell body called dendrites and axons. Dendrites are extensions of neuron's cell body or soma that receive signals and conduct them toward the cell body.

OXYGEN CYCLE;
The oxygen cycle describes the various forms in which oxygen is found and how it moves through different reservoirs on Earth. It is one of the biogeochemical cycles. There are three major reservoirs of oxygen: the atmosphere, biosphere, and lithosphere.
How the Oxygen Cycle takes place
Photosynthesis :– During the day, plants take energy from the sun, carbon di oxide from the air, and water from the soil to make their food. ...
Respiration :– The oxygen that is released by plants is used by humans, animals, and other organisms for respiration, i.e. breathing. ...
