What was the social structure of cities? As during all the Middle Ages, there were big differences among the population.

The Upper Classes

The upper classes were formed by two groups.

• The upper nobility continued having their privileges, and some moved to the cities and lived in palaces.

The Lower Classes

The lower classes were formed by the rest of the population.

• The commoners formed the majority. There were small craftsmen, merchants and servants. They lived modestly.

The Nephron

The nephron is the functional unit of the kidneys, responsible for filtering blood and producing urine. Each kidney contains over one million nephrons.

Parts of the Nephron

• Bowman's Capsule: Surrounds a tiny network of capillaries.
• Tubule: Shaped like a handle, the tubule of several nephrons empties into a larger tube called a collecting duct.
• Collecting Ducts: Move urine into the renal pelvis.

Kidney Function

1. Filtration: Molecules exit the bloodstream and enter the Bowman's capsule, forming filtrate.
2. Reabsorption: As filtrate travels through the tubule, some molecules are reabsorbed by the capillaries. Glucose, 99% of water, a small amount of urea, and salts return to the blood.
3. Excretion: The remaining filtrate forms urine, which is excreted

Ethical Considerations in Psychological Research

One ethical consideration in psychological research is the use of deception. Deception occurs when a participant is not made fully aware of the purpose of a study or is intentionally misinformed. Researchers often use deception to hide the true aim of an experiment. If participants knew the aim, they might demonstrate demand characteristics, either trying to give the researchers what they want or behaving in a way that makes them look their best, a phenomenon known as the social desirability effect.

Deception is problematic because it undermines the concept of informed consent. It violates the trust between a researcher and a participant. Additionally, it increases the chance that a participant... Continue reading "Ethical Deception in Research & Multi-Store Memory Model" »

The Renaissance was an artistic-cultural movement that, from Italy, spread throughout Western Europe from the 15th century. It was the cultural manifestation of a change in the European mentality that went from a theocentric world view, typical of the medieval period, to an anthropocentric one. This change, manifested in the humanist philosophical current, is considered the beginning of the Modern Age.

Principles:

• Anthropocentrism: They rejected theocentric mentality which revolved around God. They believed humans were the centre of the universe.
• Classical antiquity: They studied Greek and Latin texts and were inspired by the philosophers of antiquity.
• Scientific curiosity: They were interested in science and technological progress.

Origin:
