Eutrophication
Eutrophication is the ecosystem response to the addition of such substances to an aquatic system and includes:

- Increased biochemical oxygen demand (BOD) by saprotrophic bacteria, leading to deoxygenation (reduced dissolved

The Nervous System
The nervous system is responsible for perceiving, interpreting, and emitting responses in the face of internal and external stimuli. It has two parts:
- Central Nervous System (CNS): Consists of the brain and spinal cord. It receives information from outside and inside the body, integrates it, and decides the response to be given. It is protected by three protective membranes called meninges: the dura mater, arachnoid, and pia mater.
- Peripheral Nervous System: Formed by motor nerves

Kidney Function
Kidneys are localized in the retroperitoneal space, one on each side of the spine at the level of vertebrae T12 to L3. The right kidney is slightly lower due to the right lobe of the liver. Kidneys regulate the internal chemical composition through several processes: filtration, absorption, and secretion. Filtration begins in the glomerulus (podocyte), where a filtrate of plasma is formed. This filtrate passes into Bowman’s capsule through hydrostatic pressure. It then passes through

19th Century Spanish Nationalism: Catalonia and Basque Country
**Carlism**
One of the most important developments of the 19th century was the emergence of nationalist political movements on the periphery of the Iberian Peninsula. Until the Restoration, nationalist claims were channeled through federal republicanism and Carlism. With both of these movements weakened, new movements emerged, claiming historical rights for Catalonia, the Basque Country, Valencia, Galicia, and Andalusia.
