Determine various social,moral and economic issues in the texts listened toMeriam Gudes - Cempron
Here are three issues derived from the story and suggestions on how to avoid them:
1. Moral issue - Lay Choo working as a social escort, which her father disapproved of strongly. To avoid this, parents must guide their children to avoid risky jobs and activities that can compromise their morals. Proper parenting and open communication within the family is important.
2. Social issue - The generation gap between the taximan and the young social escorts he drives around. Young people are immature and do not respect elders. To bridge this gap, both young and old must make efforts to understand each other's perspectives through respectful dialogue.
3. Economic issue - Some people, like social escorts, engage in
Name-calling is a propaganda technique that directly or indirectly attacks an opponent through labels, stereotypes, or sarcasm. Examples include political ads that make allegations against candidates without proof. Glittering generalities use vague positive terms like "freedom" and "family values" to favorably connect with audiences. Transfer associates approval of respected entities with something being promoted. Testimonials feature endorsements from famous people to influence audiences. Plain folks creates a sense of commonality between a speaker and audience to build belief. Card stacking only uses facts that support an argument, omitting important details, while bandwagon encourages following what "everyone else" is doing.

The document discusses the history and key discoveries related to cells. It begins with Robert Hooke observing cork cells under a microscope in 1665. Later scientists like Anton van Leeuwenhoek discovered protozoa and red blood cells. The cell theory was developed based on the combined work of Schleiden, Schwann, and Virchow, stating that all living things are composed of cells, cells are the basic unit of life, and cells only come from preexisting cells. The document also describes cell diversity in size, shape, and internal structures between prokaryotic and eukaryotic cells, and provides examples of organelles like the nucleus, mitochondria, chloroplasts and their functions.
Cell biology studies the structure and function of cells. A cell is the basic unit of life and contains organelles that allow it to carry out essential functions like metabolism, energy production, waste removal, response to stimuli, and reproduction. There are two main types of cells - prokaryotic cells which lack organelles and eukaryotic cells which contain organelles within membranes. Organisms are classified into five kingdoms - Monera, Protista, Fungi, Plantae, and Animalia - based on characteristics like cell structure, nutrition, and complexity. The cytosol is the gel-like fluid found inside cells that allows for transport and chemical reactions and contains dissolved molecules, ions, and enzymes.
Evolution of prokaryotic and eukaryotic cellsE Jei Torres
Cells can be divided into two main types: prokaryotic and eukaryotic. Prokaryotic cells lack a nucleus and other organelles, while eukaryotic cells have a nucleus enclosed within membranes. It is believed that eukaryotic cells evolved from prokaryotic cells when ancient bacteria were engulfed but not destroyed by their hosts, eventually evolving into the mitochondria and chloroplasts found in modern eukaryotic cells. This endosymbiotic theory explains the origin of the more complex eukaryotic cell structure.
This document provides an overview of electrolytes and discusses sodium and potassium in detail. It begins by listing the learning objectives which are to list the roles of six important electrolytes, name disorders of abnormal levels, identify the predominant extracellular anion, and describe aldosterone's role in water balance. It then discusses sodium and potassium individually, outlining their normal levels, functions, dietary sources, and related imbalances.
The document discusses the interdependence between the nucleus and cytoplasm in a cell. It provides several examples of experiments that demonstrate how the nucleus controls cytoplasmic activities but also how the cytoplasmic state can influence nuclear behavior and gene expression. Specifically, it notes that enucleated cells can perform some functions but ultimately die without the nucleus, while transferring nuclei between cells shows the nucleus determines traits like cap morphology. The cytoplasmic environment can also reactivate dormant nuclei, as seen when red blood cell nuclei are fused with other cell types. In conclusion, both the nucleus and cytoplasm are necessary as the nucleus directs processes but relies on the cytoplasm as an energy source.
The document discusses the history and key concepts of cell biology. It describes how Robert Hooke first observed cells in 1665 using a microscope. The cell theory developed in 1838, stating that all living things are made of cells, cells only come from pre-existing cells, and the cell is the basic unit of structure and function. There are two main types of cells - prokaryotic cells which lack nuclei, and eukaryotic cells which have membrane-bound nuclei and organelles. Cellular reproduction occurs through binary fission in prokaryotes and mitosis and meiosis in eukaryotes to produce new cells.
Cell biology for the under graduate courseshashi4d
The document summarizes the origin and evolution of cells. It describes how cells evolved from simple organic molecules into prokaryotic and eventually eukaryotic cells over billions of years. Prokaryotic cells were the first to emerge lacking organelles and nuclei. Eukaryotic cells later developed through endosymbiotic events incorporating organelles. Key events included the development of lipid membranes to enclose genetic material and metabolic pathways like glycolysis and photosynthesis that generated energy and changed Earth's atmosphere.
The basic unit of life is the cell. All living things are composed of cells, which are the basic units of structure and function. Cells come in two main types - prokaryotic cells, which lack a nucleus and membrane-bound organelles, and eukaryotic cells, which have a nucleus enclosed within membranes and other membrane-bound structures. Cells vary greatly in their size, shape, and internal structures, depending on their function in different living things.
Describe The Relationship Between Organelles And EukaryotesPaula Smith
The document discusses the relationship between organelles and eukaryotic cells. It states that the cytoskeleton and Golgi apparatus are organelles found only in eukaryotic cells, not prokaryotes. The cytoskeleton provides shape and support to cells, while the Golgi apparatus modifies and packages macromolecules. Mitochondria and plastids can also be found in eukaryotic cells and were originally prokaryotes that developed into organelles through endosymbiosis.
Eukaryotic cells contain membrane-bound organelles, including a nucleus. Eukaryotes can be single-celled or multi-celled, such as you, me, plants, fungi, and insects. Bacteria are an example of prokaryotes. Prokaryotic cells do not contain a nucleus or any other membrane-bound organelle.
- The cell is the fundamental structural and functional unit of all living organisms. Robert Hooke first observed cells in 1665 from a slice of cork under a microscope.
- Cells may be unicellular, consisting of a single cell, or multicellular, consisting of many cells. All cells contain a nucleus and membrane-bound organelles and have the ability to reproduce.
- Key characteristics of cells include providing structure and support, containing genetic material in the nucleus, and using mitochondria and other organelles to carry out essential functions like energy production and waste digestion.
This document summarizes key aspects of protists, including their taxonomy, characteristics, Lynn Margulis' endosymbiont hypothesis of their evolution from prokaryotes, and descriptions of major protist phyla including animal-like protists (Ciliophora, Ameba) and plant-like protists (Euglenophyta, Pyrrophyta, slime molds). It notes the challenges of classifying unicellular eukaryotes before the kingdom Protista was established.
The cell is the basic unit of structure and function of all living organisms. Cells consist of a membrane that encloses cytoplasm and organelles like the nucleus, mitochondria, and chloroplasts. Organisms are either unicellular, made of a single cell, or multicellular, made of many cells. The cell was discovered in 1665 and contains the genetic instructions to direct its functions. Key parts of the animal and plant cell include the cell membrane, nucleus, cytoplasm, mitochondria and in plant cells, chloroplasts and a cell wall. The organelles each have specific functions like producing energy, transporting materials, and carrying out genetic instructions.
This document provides an introduction to cell biology. It discusses key topics like what is a cell, the cell theory, differences between prokaryotic and eukaryotic cells, cell size and structure, and early discoveries of cells by scientists like Hooke, Leeuwenhoek, Schleiden, and Schwann. It also outlines course policies and provides an overview of topics to be covered, including cell organelles, cell types, microscopy, and cell evolution.
1. Robert Hooke first observed cells in 1665 when examining a thin slice of cork under a microscope. He saw that the cork resembled a honeycomb structure made up of many small compartments, which he called cells.
2. The cell theory, developed by Schleiden and Schwann in 1838-1839, states that all living things are composed of cells, and the cell is the basic unit of life.
3. Cells can be unicellular, with a single cell constituting the whole organism, or multicellular, with many cells grouped together to form organisms like plants and animals.

Life is distinguished from non-living things by biological processes like metabolism, homeostasis, reproduction, and response to stimuli. It first appeared on Earth over 3.8 billion years ago in the form of microorganisms. While there is no consensus on a definition, life is generally characterized as open systems that maintain homeostasis, are made of cells, undergo metabolism and reproduction, and evolve over time. Biology studies the diverse forms of life including plants, animals, fungi, and microorganisms.
