The periodic table organizes the chemical elements. Over time, scientists like Dobereiner, Newlands, and Mendeleev contributed to recognizing patterns in elements' properties that allowed organizing them into the periodic table. Mendeleev was the first to organize elements into a periodic table based on atomic mass. Later, Moseley determined elements should be organized by atomic number of protons. Today's periodic table arranges elements by atomic number, providing order and enabling prediction of undiscovered elements.
This document discusses substance abuse and drug addiction. It defines substance abuse as using drugs in harmful amounts or methods. Common effects of drug abuse include criminal behavior, health issues, lost opportunities, and risky behaviors. The types of drugs discussed and their effects are cocaine (paranoia and compulsive behaviors), stimulants (anxiety and sleep issues), LSD and ecstasy (hallucinations), and alcohol, sedatives, and narcotics (depression and mood issues). The document also discusses genes, environment, development, and stress as factors that can influence drug abuse. It provides prevention strategies like avoiding peer pressure, connecting with supportive friends, and enjoying life through constructive activities rather than using drugs.
The document discusses cells and their structure. It explains that cells are the basic unit of life and come in different shapes and sizes depending on their function. Both plant and animal cells have a cell membrane, cytoplasm, and nucleus, but plant cells also contain additional structures. The document compares typical animal and plant cells and their organelles. It describes how cells are specialized to perform different jobs and how multicellular organisms are made up of organized systems of tissues and organs composed of groups of similar cells.

It also discusses self-esteem, body esteem, and what influences these. The document outlines causes of stress and strategies for coping, including recognizing stress, identifying support systems, and maintaining well-being. Statistics on mental health issues among youth are also presented.
There are two transport systems in plants - xylem and phloem. Xylem vessels transport water and minerals up from the roots through hollow tubes made of lignin. Phloem vessels transport sugars and amino acids throughout the plant through living cells connected by pores. Water moves up xylem vessels through capillary action and transpiration. Transpiration is the loss of water vapor from leaves through stomata and is affected by temperature, wind, humidity, and light intensity. Plants have adaptations like waxy cuticles, sunken stomata, and water storage to reduce water loss in dry climates.
Chapter 6 Nutrition in Humans Lesson 2 - Absorption and Assimiliationj3di79
The document summarizes absorption and assimilation of nutrients in the small and large intestines. It describes how the small intestine absorbs simple sugars, amino acids, fatty acids, and glycerol through microvilli in the jejunum and ileum. The large intestine absorbs water and mineral salts from undigested materials. Absorbed nutrients are transported to the liver via the bloodstream. The liver plays a key role in regulating blood glucose, storing iron, synthesizing proteins, detoxifying harmful substances, and producing bile.

The document presents information about photosynthesis. It defines photosynthesis as the process by which plants use sunlight, carbon dioxide, and water to produce food (glucose) and oxygen. The key requirements for photosynthesis are explained as water, carbon dioxide, light energy from the sun, and chlorophyll. The document also notes that photosynthesis occurs within chloroplasts in the leaves of plants and describes the basic photosynthesis equation and products.
This document discusses drug addiction among teenagers in the Philippines. It outlines the top 5 drugs used - methamphetamine, cocaine, inhalants, heroin, and marijuana - and describes their common signs and effects. It also provides tips for recognizing drug abuse in teenagers through issues at school, health problems, neglected appearance, behavioral changes, and frequent requests for money. Finally, it discusses solutions for drug addiction through 12-step programs that help recovering addicts forge relationships, acknowledge their powerlessness over addiction, and develop alternative coping strategies.
Metabolism is the sum of all chemical reactions within an organism. Metabolic pathways consist of enzyme-catalyzed reactions organized into linear chains or cyclic pathways. Enzymes lower the activation energy of reactions by binding to substrates and altering their structure. Enzyme inhibitors can competitively or non-competitively bind to enzymes and reduce their activity. Metabolic pathways are regulated by end-product inhibition, which stops pathways once their product reaches a certain concentration. Databases can be used to screen chemicals and identify potential new drugs, like anti-malarial treatments. Rates of enzymatic reactions can be calculated from experimental data and plotted on graphs to determine inhibition type.
Homeostasis refers to the concept of maintaining stable internal conditions in living organisms. The document provides examples of how homeostasis regulates important internal factors like body temperature, water levels, glucose levels, and blood pressure. It explains that receptors detect changes in these conditions and negative feedback mechanisms kick in to return the levels back to normal. For instance, if body temperature rises, the hypothalamus triggers sweating and increased blood flow to the skin to cool down. Overall, homeostasis is how the body automatically counteracts disturbances to keep its internal environment in a stable state.
Chapter 3 Movement of Substances Lesson 2 - Effects of isotonic, hypotonic & ...j3di79
The document discusses isotonic, hypotonic, and hypertonic solutions and their effects on cells.
An isotonic solution has an equal concentration to a cell, so there is no net movement of water into or out of the cell. A hypotonic solution has a lower concentration than a cell, so water will move into the cell by osmosis, causing it to swell. A hypertonic solution has a higher concentration than a cell, so water will move out of the cell by osmosis, causing it to shrink or crenate.
Alcohol is created through fermentation and affects the central nervous system as a depressant. While some teens drink out of curiosity or to fit in, drinking has significant health and legal risks for teens. Long term heavy drinking can lead to health issues like alcoholism, alcohol poisoning, and cirrhosis of the liver.
This document provides information about cell division through mitosis and cytokinesis. It begins with definitions of key terms like interphase, prophase, metaphase, anaphase, telophase, and cytokinesis. Images and descriptions are provided of each stage of mitosis in animal and plant cells. The roles of the centrioles, spindle fibers, chromatids, and chromosomes are explained. The final stages of cytokinesis are described, with plants noted to form a cell plate rather than dividing through inward movement. Review questions are included to test understanding of mitosis.
Heredity is the passing on of characteristics from one generation to the next. It is the reason why offspring look like their parents. It also explains why cats always give birth to kittens and never puppies. The process of heredity occurs among all living things including animals, plants, bacteria, protists and fungi. The study of heredity is called genetics and scientists that study heredity are called geneticists.
Through heredity, living things inherit traits from their parents. Traits are physical characteristics. You resemble your parents because you inherited your hair and skin color, nose shape, height, and other traits from them.
Cells are the basic unit of structure and function of all living things. Tiny biochemical structures inside each cell called genes carry traits from one generation to the next. Genes are made of a chemical called DNA (deoxyribonucleic acid). Genes are strung together to form long chains of DNA in structures known as chromosomes. Genes are like blueprints for building a house, except that they carry the plans for building cells, tissues, organs, and bodies. They have the instructions for making the thousands of chemical building blocks in the body. These building blocks are called proteins. Proteins are made of smaller units called amino acids. Differences in genes cause the building of different amino acids and proteins. These differences cause individuals to have different traits such as hair color or blood types.
A gene gives only the potential for the development of a trait. How this potential is achieved depends partly on the interaction of the gene with other genes. But it also depends partly on the environment. For example, a person may have a genetic tendency toward being overweight. But the person's actual weight will depend on such environmental factors as how what kinds of food the person eats and how much exercise that person does.
Traits are characteristics about an individual. Inherited traits are received from biological parents through genes and include eye color, hair color, and blood type. Acquired traits develop during life through learning and experience, like skills learned or injuries received, and are not passed to offspring. Some traits have both inherited and acquired aspects, like skin color being determined partly by genes and partly by sun exposure.
The endocrine system is made up of glands that produce hormones which regulate various bodily functions like metabolism, growth, mood, and reproduction. The main glands are the pituitary gland, thyroid gland, parathyroid glands, adrenal glands, pancreas, ovaries, and testicles. Hormones are chemicals that control tissues and organs and are involved in processes like reproduction, growth, and immune function. They work slowly compared to the nervous system. Hormonal changes can impact mood, weight, and other factors. The document then discusses various hormones like cortisol, oxytocin, thyroid hormones, estrogen, and testosterone in more detail. It also covers the nature vs nurture debate about how much our

On 24th of February 2022, Russia attacked Ukraine. That is simply wrong. President Putin, who is pretending to be orthodox, is attacking other orthodox people in Ukraine. In this kind of situations, solidarity is needed even if that solidarity does not come from religion.
On slide #8, I used the word "usually" / "useimmiten", though the more correct word might be "sometimes" / "joskus". When reading my slides in general, do not pay too much attention on single words when not necessary. Please pay attention on mathematical formulas and relevant ideas instead.
