Mitosis
Cells divide through the process of mitosis in order to grow, repair, and replace old or damaged cells. Mitosis produces two identical daughter cells from one parent cell through four stages: prophase, metaphase, anaphase, and telophase. Each daughter cell has the same number and type of chromosomes as the original parent cell to ensure genetic identicalness. Cell division through mitosis allows for the growth, maintenance, and asexual reproduction of many organisms.

Elements and Compounds
This document defines key chemistry concepts such as elements, compounds, and mixtures. It notes that elements are pure substances that cannot be broken down further, while compounds contain two or more elements chemically bonded together. The document also discusses trace elements essential for life like boron, copper, iodine, selenium, zinc, and iron, and some of their functions and dietary sources. It introduces the periodic table and explains that compounds have properties that may differ from their constituent elements.
Mitosis in detail
Cells divide through the process of mitosis in order to grow, repair, and replace old or damaged cells. Mitosis involves the equal distribution of a mother cell's chromosomes between two daughter cells to ensure each cell has the full complement of DNA. It occurs in four stages - prophase, metaphase, anaphase, and telophase - followed by cytokinesis where the cytoplasm is divided. This process guarantees that the two daughter cells are genetically identical to the original mother cell and to each other.

Lipids
Lipids include fats and steroids. Fats are commonly known as triglycerides, which are composed of a glycerol molecule bonded to three fatty acid chains. Lipids serve several important functions in the body - they act as boundaries in cell membranes, store and transport energy, cushion and insulate tissues, and act as chemical signals or hormones. Lipids can be saturated or unsaturated depending on whether the fatty acid chains contain single or double carbon bonds. Steroids also contain carbon skeletons and serve structural or signaling roles like cholesterol in cell membranes and hormones like estrogen and testosterone.

Meiosis and genetic variation (first ppt)
Homologous chromosomes are pairs of chromosomes, one inherited from each parent, that pair up during meiosis. Sister chromatids are identical copies of the same replicated chromosome. During meiosis I, homologous chromosomes separate, reducing the number of chromosome sets from diploid to haploid. Meiosis II then separates the sister chromatids, completing meiotic cell division with four haploid daughter cells each containing one representative from each homologous pair of the original cell.
Organic Molecules summary
The document discusses the basic building blocks and polymers of organic biomolecules. It explains that carbohydrates are made of monosaccharides that polymerize to form polysaccharides, lipids are made of fatty acids and glycerol that form fats or contain steroid rings, and proteins are composed of amino acids that join to form polypeptides and proteins. Nucleic acids are also mentioned as being made of nucleotides that make up chromosomes.
Chloroplast and Mitochondria
This document discusses the organelles mitochondria and chloroplasts and their roles in cell processes. Mitochondria are described as the "powerhouses" of cells that break down sugars and oxygen to produce ATP through cellular respiration, providing energy. Chloroplasts are structures in plant cells that capture solar energy through photosynthesis to produce ATP and sugars from carbon dioxide and water. Both organelles play essential roles in energy production for cells, with mitochondria generating ATP through respiration and chloroplasts generating ATP and sugars through photosynthesis using sunlight.
Molecules of life 9th grade
This document discusses the four main types of organic molecules that make up living cells: carbohydrates, lipids, proteins, and nucleic acids. It explains that carbohydrates like sugars are a major source of fuel for cells and are made up of monomers like glucose. Lipids including fats and steroids function in energy storage, insulation, and as chemical messengers. Proteins are made through linking amino acid monomers and perform most functions in cells, such as structure, storage, defense. Enzymes, a type of protein, act as catalysts to speed up chemical reactions by lowering their activation energy. The document provides details on the structures, functions, and reactions of these essential biomolecules that make up living organisms.
Form gene to protein and bingo
General concepts and ideas about the flow of information form gene to protein, and the instructions to play "codon bingo"
Protein structure and shape, Denaturation and Enzymes
This document discusses protein structure and enzymes. It explains that proteins are composed of polymers of amino acids linked by peptide bonds. The specific sequence and interactions between amino acid side chains cause proteins to fold into precise three-dimensional shapes that determine their functions. Enzymes are proteins that act as catalysts to speed up biochemical reactions, binding specifically to substrate molecules in a "lock and key" fashion. Proteins can be denatured by factors like heat, acids, bases, salts, or agitation, disrupting their normal shape and impairing their functions.

1) Helicase enzyme breaks the hydrogen bonds between the DNA strands, unwinding the double helix.
2) DNA primase binds to the unwound strands and adds RNA primers that will serve as starting points for DNA replication.
3) DNA polymerase then uses the parent strands as templates to build new complementary strands in a 5' to 3' direction by adding nucleotides, forming the leading strand continuously and the lagging strand in fragments called Okazaki fragments
ADN y el lenguaje de la vida
Este documento resume conceptos clave sobre ADN y el lenguaje de la vida, incluyendo que un gen es una porción del ADN que contiene instrucciones para hacer proteínas, las proteínas son cadenas de aminoácidos que llevan a cabo muchas funciones en el cuerpo, y los genes se empaquetan en cromosomas que determinan características físicas.
Generalidades de la célula
Este documento resume las características generales de las células. Todas las células están compuestas de una membrana, citoplasma y ADN. Existen dos tipos principales de células: procariotas y eucariotas. Las células animales y vegetales comparten organelos como las mitocondrias y ribosomas, pero difieren en aspectos como la presencia de cloroplastos y vacuolas en las células vegetales. Las células madre indiferenciadas pueden producir otras células especializadas que formarán los te

A Strategic Approach: GenAI in Education
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
