Human Body Anatomy: Head to Toe

Inside the head is the brain, which is responsible for thinking. The top of a person's scalp is covered with hair. Beneath the hairline at the front of the face is the forehead.

Underneath the forehead are the eyes for seeing, the nose for smelling, and the mouth for eating. On the outside of the mouth are the lips, and on the inside of the mouth are the teeth for biting and chewing food, and the tongue for tasting. Food is swallowed down the throat.

At the sides of the face are the cheeks, and at the sides of the head are the ears for hearing. At the bottom of a person's face is the chin. The jaw is located on the inside of the cheeks and chin. The neck is what attaches the head to the upper body.

What Is the Economy?

Often, when you are in high school, you feel that many subjects will not help you in your future life. It is common to hear students complaining about various subjects because they do not see a direct application to their everyday life—asking, "When am I going to use this?" Luckily, this does not happen with economics, a subject that will allow you to solve many of your real-world problems.

But what is economics? The late José Luis Sampedro would tell you that you are the economy. However, you likely want a more elaborate answer. Let us begin.

The Necessity of Choice

Because our resources (such as money and time) are scarce, but our needs are unlimited, we must choose how to use these resources and which needs to cover.

Direct Speech (El Estilo Directo)

When we want to report exactly what another person has said, we use direct speech. With this style, what the person said is placed between quotation marks (“...”) and must be word for word.

Examples of Direct Speech

• “I am going to London next week,” she said. (“Voy a Londres la semana que viene,” ella dijo.)
• “Do you have a pen I could borrow?” he asked. (“¿Tienes un bolígrafo que puedas prestarme?” él preguntó.)
• Alice said, “I love to dance.” (Alice dijo, “Me encanta bailar.”)
• Chris asked, “Would you like to have dinner with me tomorrow night?” (Chris preguntó, “¿Te gustaría cenar conmigo mañana por la noche?”)

Weight Management Concepts

2. Distinguishing Hunger and Appetite

• Hunger: The body’s response to the need for food.
• Appetite: A desire, rather than a need, to eat certain types of food.

3. Distinguishing Overweight and Obese

• Overweight: Used to describe a person who is heavy for his/her height.
• Obese: A person has a significant amount of excess body fat.

4. Importance of Energy Balance in Weight Management

Energy balance is crucial for maintaining weight:

• Eating extra food energy increases the body’s fat stores and causes weight gain.
• Eating less food than you need decreases the body’s fat stores and causes weight loss.

5. Reasons for Food Choices

People choose certain foods based on several factors:

• The smell and taste of the food
• Mood
• Family tradition

Literary Movements

Període de desorientació i silenci. A partir dels anys 50 amb la creació de col·leccions com 'El club dels novellistes' comencen a publicar les seues obres. Són molt allunyades dels corrents novel·lístics a Europa. Intenten explicar la realitat a través del simbolisme i el mite.

Pedrolo, Pere Calders: començà a publicar abans de la guerra. Cròniques de la veritat oculta: un recull de narracions on entren en conflicte la realitat i la irrealitat, l'absurd.

If a person were to eat a diet that provided carbohydrates, fat, and micronutrients, but very little protein, for example, if he or she ate only whole-wheat pita bread with olive oil, the body would break down muscle tissue to provide amino acids to make essential proteins.

Protein Intake and Recommended Dietary Allowance

If a man weighs 190 lb and eats 150 g protein per day, his protein intake is greater than 200% of the Recommended Dietary Allowance (RDA).

Protein Structure

Some proteins contain an alpha helix, which is part of their secondary structure.

Amino Acids

The most accurate statement about amino acids is that essential amino acids cannot be manufactured by body cells. Nonessential amino acids can be made by the liver from other amino

The Unpredictable Fury of Nature

In December 2004, Pat Ralston was enjoying a luxurious stay at a Thai hotel. As he relaxed on the balcony, engrossed in a book, the beach below buzzed with volleyball players. The sun painted a picture of paradise. Suddenly, the idyllic scene dissolved into chaos as a tsunami roared ashore, engulfing the beach and hotel in its watery grip. Pat miraculously survived, but the immense wave left a trail of devastation across Southeast Asia, claiming thousands of lives and reducing buildings and villages to rubble.

Even the seemingly safe haven of a ship offers no guarantee against nature's wrath. In April 2005, the cruise ship Norwegian Dawn encountered a monstrous 21-meter wave near the Bahamas after battling two...
