Magical Realism: Characteristics, Themes, and Key Figures
Magical Realism: A Literary Analysis
Magical realism, a literary and metalinguistic product of the discrepancies between two visions that coexisted in Latin America – the culture of technology and the culture of superstition – is defined by its stylistic concern and interest in portraying the unreal or strange as something common and everyday. It is an attitude toward reality that shares with epic realism features like an internally credible claim to the fantastic and unreal, unlike the nihilistic

The Cell
The cell is classified as the driving, morphological, physiological, and reproductive element of living beings. It is classified as eukaryotic. In prokaryotes, it exists in all living organisms with a defined nucleus, mitochondria, and Golgi apparatus.
Plasma Membrane
The plasma membrane is made up of lipids, phospholipids, and membrane proteins distributed in layers. Certain proteins are enzymes; others are receptors for hormones or other substances.
Fundamental Parts of the Cell
The fundamental

Nervous System
A complex network of nerves and cells that transmit signals between different parts of the body, responsible for controlling and coordinating bodily functions.
Neuron: A nerve cell that carries electrical signals in the nervous system.
Neurotransmitter: Chemical substances that transmit signals across a synapse from one neuron to another or to a target cell (e.g., dopamine, serotonin).
Synapse: The junction between two neurons, or between a neuron and a target cell (e.g., muscle, gland)

Evolution and Natural Selection
Evolution is the gradual and continuous accumulation of heritable changes in populations that give rise to new species.
Fixism
This theory holds that species remain fixed and immutable from the beginning to the present day. Fixist theories are strongly influenced by myths and religious beliefs.
Main Fixists
- Linnaeus grouped organisms according to their degree of similarity.
- Cuvier, a French anatomist, was a defender of fixist theories. To explain the existence of fossils,
Skeletal Muscle Structure, Function, and Nervous System Integration
Functions of the Skeletal System
- Move the body
- Maintain posture
- Protect and support
- Regulate elimination of materials
- Produce heat
Characteristics of Skeletal Muscle
- Excitability: Ability to respond to a stimulus by changing electrical membrane potential
- Conductivity: Sending an electrical change down the length of the cell membrane
- Contractility: Enables movement when filaments slide past one another
- Extensibility: Ability to stretch
- Elasticity: Ability to return to original length after shortening or lengthening
Muscle

What is Nutrition?
Nutrition is the process by which cells incorporate elements and perform nutritional functions. Cells are grouped in the following way: cells associate to form organs, organs coordinate to form systems, and systems cooperate to allow your body to function, think, work, and play.
Metabolism: A Series of Chemical Reactions
Metabolism includes anabolism (building tissues like muscle, bone, and blood) and catabolism (breaking down substances and tissues).
Food provides fuel for these
