Symbolic Interaction and Inequality
Ideology often justifies inequality, leading us to accept it.
Consequences of Inequality
- Economic Differences
- Life Chances: Opportunity to succeed
- Health: Wealthier individuals tend to be healthier
- Education: Wealthier individuals often have access to better education
- Work Life: Disparities exist between the working conditions of the poor (e.g., factories) and the rich (e.g., offices)

Earth’s Resources and Pollution: A Comprehensive View
Natural Resources
Natural resources are materials found in the environment that are useful to humans. There are two main types:
- Non-renewable resources: These resources have geological origins and take thousands of years to regenerate, making them limited. Examples include land, fossil fuels, and minerals.
- Renewable resources: These resources are generated continuously and are not limited. Examples include solar energy, wind energy, and resources obtained from animals and plants.

The Disaster of 98 and Its Consequences
Only the Socialists, through their minority media outlets, and the Federalists of Pi y Margall had raised their voices in Spain advising the emancipation of the Caribbean island in prevention of fatal consequences and a useless sacrifice of human lives. The Catalan political advocated independence if it were determined in a free plebiscite by most Cubans. Even Admiral Cervera, convinced of the inferiority of the Spanish fleet, deemed it wiser to use it in defending

Nucleotides
The nucleotides are formed by the union of one molecule of phosphoric acid and a nucleoside via the hydroxyl group of the fifth carbon (carbon 5′) of the pentose. It is, therefore, a phosphoric ester of nucleoside. The nucleotides are strongly acidic due to the phosphate group that is ionized. Nucleotides are named by adding the term 5′-monophosphate to the name of the nucleoside. Thus, the RNA nucleotides are adenosine-5′-monophosphate (AMP), guanosine-5′-monophosphate (GMP), cytidine-

Beckett’s Tragicomedy in ‘Waiting for Godot’
Beckett classified his play as a “tragicomedy.” Is this an accurate classification? If not, how else might the play be classified? Does the play lean more towards tragedy or comedy?
The play is often considered a tragicomedy because it conveys tragic themes through comedic elements. What makes it tragic? For instance, the characters desire to find meaning in human existence and to be completely independent. However, Estragon and Vladimir cannot separate

Book Review: “Al final del camino”
Last summer, I read a really nice and interesting book titled “Al final del camino” by the Spanish writer Lucía Gabildo.
The book tells the story of four different people: Gloria, a young woman who paints fantastically and works cleaning in an office by night; her neighbor Pablo, a real gentleman who lives in a big apartment and sells postcards in a museum; Fran, Pablo’s tenant and an excellent cook; and Fran’s grandmother, Paula, who lives in an old people’s home.

River Deltas: Formation and Characteristics
DELTA: A delta is a triangular landform created at the mouth of a river by the deposition of sediments as the river flows into a larger body of water. The river often splits into multiple channels, forming islands of deposited sediment. Deltas and estuaries are the primary types of river mouths found in seas, lakes, oceans, or other major rivers. Their formation is influenced by the tidal range.
