Digestive System

Main Function

The main function of the digestive system is the digestion and absorption of nutrients.

Layers of the Digestive Tract

• Mucosa: Formed by different types of epithelium depending on the zone.
• Muscularis Mucosa: Smooth muscle tissue, predominantly circular.
• Submucosa: Formed by connective tissue, blood vessels, and nerves.
• Muscularis: Formed by 2 or 3 layers of muscle tissue.
• Adventitia/Serosa: Consists of loose connective tissue or peritoneum depending on the zone.

Parts of a Tooth

• Root: Within the alveolar bone cavity.
• Crown: External, visible part of the tooth.
• Neck: Separates the root from the crown.
• Pulp Chamber: Formed by pulp, connective tissue, blood vessels, and nerves.
• Dentin: Hard tissue surrounding the pulp, covered

**Chlorophyll Function**

Chlorophyll function: The process by which plants absorb CO2 for subsequent decomposition; oxygen is released by this means.

**Starch**

Starch: A polysaccharide like starch that is in seeds, tubers, and roots used by plants. It is used primarily in the food industry in the elaboration of flour.

**Taro**

Taro: A tropical plant used as a vegetable for its corm. It is also edible as a vegetable, but it is indigestible when raw due to substances in the ergastic cells of the plant. It grows where there is a lot of water.

**Corm**

Corm: A thickened underground stem with a swollen base and vertical growth. It contains nodes and bulges where the buds come out, and it is covered by layers of leaves.

**Cassava**

A perennial shrub, Cassava,... Continue reading "Understanding Essential Plant Processes and Food Crops" »

Skeletal Striated Muscle Cells

Skeletal striated muscle cells are elongated and have hundreds of peripheral nuclei. The cytoplasmic membrane (sarcolemma) encloses the cytoplasm (sarcoplasm), which is packed with:

• Myofibrils
• Sarcoplasmic reticulum
• T tubules
• Mitochondria

Myofibrils are composed of sarcomeres arranged in series. Each myofibril consists of thin (actin) and thick (myosin) myofilaments.

Sarcomere Structure

The sarcomere (from Greek sarco meaning "flesh" or "meat" and meres meaning "part") features:

• A central, dark A band (anisotropic)
• Two peripheral, light I bands (isotropic)

The sarcomere contains globular proteins such as troponin and tropomyosin. The sliding of thin filaments between thick filaments causes muscle contraction. During contraction,... Continue reading "Striated Muscle Cells: Skeletal vs. Cardiac" »

Atmosphere: Layers and Properties

The atmosphere is a gaseous and tiered layer with vertical physical properties surrounding our planet. It extends super above 1000km.

Troposphere

The troposphere extends up to 13km and contains 75% of the total mass of the atmosphere. Most atmospheric phenomena occur here, with abundant vertical flows. The lower troposphere is followed by the tropopause, a transition layer where jet streams flow, influencing weather patterns. The location and intensity of these systems change with time and latitude.

Stratosphere

The stratosphere spans from 13 to 50km. In Caracas, the isotherm is practically at its lowest point, around -40°C. This layer contains ozone (O3), which absorbs UV radiation and heats the air.

Mesosphere

The... Continue reading "Atmospheric Layers: Properties, Pressure, and Weather Variables" »

ITEM 7: Types of Dismissal

Collective Dismissal

Concurrent economic, technical, organizational, or production reasons.

• Companies with fewer than 100 employees: Minimum of 10 dismissals.
• Companies with 100 to 300 employees: Minimum of 10% of the workforce.
• Companies with 300 or more employees: Minimum of 30 dismissals.

Objective Dismissal

• Worker's inability to perform their duties.
• Lack of worker adjustment to job requirements.
• Amortization of jobs.
• Truancy.
• Lack of budget.

Disciplinary Dismissal

• Repeated and unjustified absences or lateness.
• Insubordination or disobedience.
• Verbal or physical abuse towards the employer.
• Violation of contractual good faith.
• Continued decrease in work productivity.
• Habitual drunkenness.
• Harassment based on race or other protected

Key Business Concepts

Economic Factors

Differentiating factor: Price can be a decisive factor for a product. For example, a cafeteria can be oriented based on price, class, or other demographics.

Practical Factors

Practical factors, such as comfort and confidence, can influence purchase decisions. An example of this is home delivery.

Aesthetic Factors

Aesthetic factors, like an attractive package, color, and size, can appeal to customers.

Technical Factors

Consider what unique features your product offers compared to others.

Psychological Factors

Psychological factors relate to social status and fashion.

Product

A product is anything offered for consumption in the market.

Product Levels

• Basic: The core need the consumer expects to satisfy.
• Formal: Something

This document presents a Java class named Student, demonstrating object-oriented programming principles. It includes attributes, constructors, getters, setters, and methods to calculate average grades and determine student status.

Test Class

import java.io.*;
public class Test {
    public static void main(String[] args) throws IOException {
        Student student = new Student("John", true, 3, 2, 5, 43);
        student.show();
    }
}

Student Class

import java.io.*;
public class Student {
    private int note1, note2, note3;
    private String name;
    private int age;
    private boolean sex; // attributes

    public Student() {

The Role of Memory in Intellectual Development

Memory is an important factor in intellectual development, influencing thought processes and information processing. Vygotsky considered the relationship between thought and memory, stating that for a young child, "to think means to remember." Current studies focus on the theoretical and evolutionary aspects of storage, coding, and retrieval. These are important from an educational point of view as they allow us to understand different memory strategies in children's short-term memory.

Short-term memory allows us to retain data briefly. For example, a child may remember the mobile toy immediately after seeing it. However, if strategies are not used to retain the information, it will be forgotten.... Continue reading "Memory, Cognition, and Psychomotor Development in Early Childhood" »
