The document discusses several biological processes related to homeostasis, including thermoregulation, osmoregulation, excretion, and feedback mechanisms. Thermoregulation involves various systems working to maintain steady body temperature through processes like evaporative cooling and heat shock proteins in plants. Osmoregulation requires adaptations for water balance in land animals like waxy skins and drinking moist foods, while plants employ strategies like thick, waxy leaves and positioning stomata. Excretion eliminates waste through various routes in both plants like shedding leaves and animals like sweating, breathing, and urinating. Feedback mechanisms can be negative, counteracting changes, or positive, increasing changes away from set points to enable rapid responses.

Cell injury cell swelling necrosis fatty change
Cell injury can be reversible or irreversible. Reversible cell injury involves cell swelling and changes to organelles. Irreversible injury leads to cytoplasmic and nuclear changes, as well as damage to mitochondria and plasma membranes. Failure of ATP production in mitochondria during ischemia or hypoxia can cause failure of the sodium-potassium pump, leading to intracellular sodium and calcium accumulation and cellular swelling. There are several types of cell necrosis characterized by different morphological features, including coagulative, liquefactive, caseous, fat and fibrinoid necrosis.

Human physiology
Human physiology explains the biological and chemical factors responsible for life through the study of the structure and function of the human body. The human body is made up of cells that come together to form tissues, organs and body systems. These systems work interdependently to maintain homeostasis, or internal stability, which is essential for survival. The major body systems include the circulatory, respiratory, digestive, urinary, integumentary, nervous, endocrine, immune, skeletal, and reproductive systems.
Homeostasis
Homeostasis refers to the body's ability to maintain stable internal conditions such as temperature and glucose levels. It is regulated by negative feedback mechanisms. For example, temperature receptors in the skin sense changes and send signals to the hypothalamus in the brain. If body temperature rises, the hypothalamus activates sweating and blood vessel dilation to cool the body through evaporation. Conversely, it triggers shivering and vessel constriction when temperatures fall to conserve heat. Various organs also help regulate variables through hormones, like the liver controlling glucose with insulin secretion. The skin plays an important role in homeostasis through insulation, sweating, and temperature reception.

The Cell
Cells are the basis of life—the basic structural unit of living things. Molecules such as water and amino acids are not alive but cells are! All life is comprised of cells of one type or another.
One of the hallmarks of living systems is the ability to maintain homeostasis, or a relatively constant internal state. The cell is the first level of complexity able to maintain homeostasis, and it is the unique structure of the cell that enables this critical function.
In this section of the course, you will learn about the cell and all the parts that make it functional. You will also focus on the cell membrane, which is the structure that surrounds the cell and separates its internal environment from the external environment. It is a critical component because it controls what can enter and exit the cell. This section will also describe how cells reproduce to maintain homeostasis.Cells are the basis of life—the basic structural unit of living things.

Physiology definition
This document provides an introduction to the field of physiology. Physiology is the study of how the body functions at various levels of organization and the goal is to explain the physical and chemical factors responsible for life. The human body functions through homeostasis, which is the dynamic self-regulation of internal conditions. Homeostasis is maintained through various feedback systems including the nervous, endocrine, and immune systems. Regulation occurs through chemical, nervous, and autoregulation. Both negative and positive feedback loops help control important variables like blood pressure and temperature. The field of physiology seeks to understand normal human body function and how systems fail in disease in order to alleviate health conditions.
Homeostasis
The document discusses the integumentary system and its role in homeostasis. It describes the layers of the skin, including the dermis and epidermis. The skin acts as a barrier against microbes and regulates body temperature through sweating and blood flow. It also synthesizes vitamins and contains sensory receptors to detect stimuli like touch and temperature.
Unit 1 introduction to physiology
This document provides an overview of human physiology. It defines physiology as the study of functional activities and mechanisms in the biological body. It discusses the history of physiology from Aristotle to Claude Bernard, who established physiology as the scientific basis of medicine. The document outlines the major fields and levels of organization in physiology from viral to human. It also covers organ systems, body fluids, transport mechanisms, homeostasis, and feedback loops. Key concepts covered include the roles and interactions of organ systems in maintaining homeostasis as well as passive and active transport processes and negative and positive feedback regulation.
Introduction to physiology
Physiology is the study of normal cell, tissue, organ, and system function. The document outlines several key topics in physiology including:
1) Cell physiology focuses on cell function and interactions, while molecular physiology examines subcellular processes. Other specialties study specific organs or systems.
2) Cells are the basic functional units of the body and fulfill the criteria of living organisms through processes like nutrition, respiration, and growth.
3) The human body contains over 200 cell types organized into tissues, organs, and organ systems like the nervous and circulatory systems.
4) Body fluids are distributed into intracellular and extracellular compartments, which are maintained within tight concentration ranges through diffusion and buffering processes.
Digestive system
The digestive system consists of the gastrointestinal tract and glands. It ingests, digests, absorbs and excretes food and waste. The major parts include the mouth, esophagus, stomach, small intestine, large intestine, liver, gallbladder and pancreas. The mouth contains teeth for chewing and salivary glands for digestion. The stomach contains cells that secrete acid and enzymes to digest food into a liquid. The small intestine further digests this liquid and absorbs nutrients with help from the pancreas and liver. The large intestine absorbs water and excretes waste.
Powerpoint homeostasis
Homeostasis refers to the maintenance of stable internal conditions in the body despite changes in the external environment. Key organs like the skin, kidneys, liver, and endocrine and nervous systems work together to regulate factors such as temperature, pH, water concentration, and glucose levels through negative feedback loops. When detected variations in these conditions occur, systems respond to counteract the change and restore homeostasis.
Basic principles of cell injury
Cell injury can occur through various acquired and genetic causes and results in cellular adaptations or cell death. Reversible cell injury causes cellular swelling and fatty change, while irreversible injury leads to necrosis, apoptosis, or autolysis/heterolysis. Necrosis is characterized by loss of membrane integrity and cellular contents, resulting in nuclear changes like pyknosis, karyorrhexis, and karyolysis. In contrast, apoptosis is a programmed form of cell death where the cell activates enzymes to degrade its own DNA and proteins while keeping the plasma membrane intact.
Pathogenesis of cell injury
1. The presentation discusses the pathogenesis of cell injury, outlining factors like the type, duration, and severity of injurious stimuli and the target cell's adaptability.
2. Common mechanisms of cell injury are discussed, including ATP depletion, mitochondrial damage, calcium influx, oxidative stress, and membrane permeability defects.
3. Specific causes of injury like ischemia and hypoxia can lead to ATP loss, pH changes, impaired sodium pumping, and decreased protein synthesis, ultimately causing reversible or irreversible cell injury.
14. Sense Organs
This document summarizes the key structures and functions of the human sense organs. It describes the four main types of stimuli that can trigger sensory responses, then details each of the main senses - touch, temperature, pain, proprioception, taste, smell, hearing, equilibrium, and vision. For each sense, it outlines the receptors, sensory pathways, and role in perceiving stimuli from the external and internal environments.
Human biology-edexcel-igcse
The document provides information on human biology covering topics such as cells and tissues, DNA, mitosis, the organization of cells into tissues and organs, biological molecules, enzymes, cell transport, the skeletal and muscular systems, coordination via the nervous and endocrine systems, the eye, ear, nutrition, and the digestive system. Key points include that animal cells contain organelles like mitochondria and ribosomes while plant cells contain chloroplasts and a cell wall. DNA contains nitrogen bases that pair together in a double helix structure. Cells specialize into tissues which further organize into organs and organ systems. The movement of substances into and out of cells occurs through diffusion, osmosis, and active transport. Coordination is achieved through the nervous
Digestion in Humans
The document summarizes digestion in human beings. It discusses the nutrients found in food and the three main types: carbohydrates, proteins, and fats. It explains that food must be digested into smaller molecules to pass through cell membranes and enter the bloodstream. Digestion is carried out by enzymes in the digestive system. The digestive system breaks down large food molecules through mechanical and chemical digestion. Mechanical digestion involves chewing and peristalsis, while chemical digestion uses enzymes to break nutrients into absorbable molecules.
Homeostasis
Homeostasis refers to the condition in which the internal environment of the body remains relatively constant despite changes in the external environment. Examples of homeostasis include maintenance of body temperature and blood glucose levels. Homeostasis is achieved through negative or positive feedback mechanisms. Negative feedback mechanisms shut off or decrease the original stimulus to reduce its intensity and reestablish homeostasis, like a thermostat. Positive feedback increases the original stimulus, such as in blood clotting. Homeostatic mechanisms involve sensors that detect changes, control centers that receive information and send messages, and effectors that receive messages and produce responses to reestablish homeostasis.
Food tests
The document describes procedures for testing foods for the presence of starch, glucose, proteins, and oils/fats. For each test, it provides the steps to perform the test along with the expected color change results for a positive or negative indication of the substance being tested. The tests involve adding reagents like iodine, Benedict's solution, Biuret reagent, or water and observing any color changes that confirm or rule out the presence of starch, glucose, proteins, or oils/fats.

Grade 12 lesson 3 homeostasis
Homeostasis refers to maintaining stable internal conditions despite external changes. The body uses control systems involving sensors, control centers, communication systems, and targets to regulate conditions like temperature, blood glucose, and blood pressure through negative and positive feedback loops. Most functions use negative feedback loops, which reverse changes to return the body to its set points. Positive feedback increases the rate of change away from set points when a rapid response is needed, such as during blood clotting or puberty.
Homeostasis
Homeostasis refers to the maintenance of stable internal conditions in the body despite changes in the external environment. It allows cells to function properly through regulatory processes like negative feedback. The skin, kidneys, liver, endocrine and nervous systems all work to keep conditions like temperature, pH, water concentration, and glucose levels within narrow limits. When deviations occur, feedback mechanisms activate processes like sweating or vasoconstriction to return the internal environment to its optimal range for cellular activity.

Homeostasis refers to maintaining stable internal conditions despite external changes. The body uses control systems involving sensors, control centers, communication systems, and targets to regulate conditions like temperature, blood glucose, and blood pressure through negative and positive feedback loops. Most functions use negative feedback loops, which reverse changes to return the body to its set points. Positive feedback increases the rate of change away from set points when a rapid response is needed, such as during blood clotting or puberty.
Homeostasis
Homeostasis refers to the maintenance of stable internal conditions in the body despite changes in the external environment. It allows cells to function properly through regulatory processes like negative feedback. The skin, kidneys, liver, endocrine and nervous systems all work to keep conditions like temperature, pH, water concentration, and glucose levels within narrow limits. When deviations occur, feedback mechanisms activate processes like sweating or vasoconstriction to return the internal environment to its optimal range for cellular activity.
Homeostasis
Homeostasis refers to the maintenance of a constant internal environment in the body through control systems. Negative feedback mechanisms work to keep physiological factors like body temperature, blood pH, and blood glucose levels within set limits. For example, the liver and pancreas work together to control blood glucose levels - the pancreas releases insulin to lower glucose and glucagon to raise it. Type 1 diabetes results from the destruction of pancreatic beta cells needed to produce insulin, leading to hyperglycemia if not treated with insulin therapy. The body also maintains a constant core temperature through vasodilation, vasoconstriction, shivering, sweating and other responses regulated by the hypothalamus.
73 Surah Al Muzzammil (The Enshrouded One)
The document is a summary of Surah al-Muzzammil, a chapter in the Quran. It discusses how Allah commands believers to spend part of the night in prayer, reciting the Quran. It mentions the rewards of obeying this command and following Allah's teachings, as well as the punishments that will befall those who reject the message. It emphasizes that Allah knows people's limitations and will reward even small acts of worship.
Chapter 4
- The document discusses the structure and function of cells, including both eukaryotic and prokaryotic cells. It describes the key components of the cell and their functions.
- The main parts of eukaryotic cells are the cell membrane, cytoplasm, organelles like mitochondria and the nucleus. Plant cells additionally contain chloroplasts and a cell wall.
- The structures and organelles work together to carry out essential functions like respiration, protein production, transport and waste removal that allow the cell to survive.
More about parts of cell sample lesson
The document compares and contrasts plant and animal cells. Plant cells have a cell wall, chloroplasts, and cytoplasm containing chlorophyll for photosynthesis. Animal cells lack a cell wall and chloroplasts. Both plant and animal cells have a cell membrane that controls what enters and exits the cell and a nucleus that stores genetic information for cell functions.

Cell reproduction
DNA is found in the nucleus of cells and makes up chromosomes. Chromosomes are composed of a single tightly coiled strand of DNA that contains the genetic instructions for building proteins. DNA is made up of nucleotides containing deoxyribose, phosphate, and nitrogen base building blocks. Genes are segments of DNA that code for specific traits. Chromosomes appear as loosely or tightly coiled structures depending on the cell's stage. Humans have 23 chromosomes in sex cells and 46 in body cells, containing a full set from each parent. Chromosomes can replicate their DNA to make copies.
Surat Al-Maun
The document criticizes those who commit various religious and social crimes. It highlights lying against the religion, neglecting orphans and the poor, lacking focus in prayer, and refusing to give charity as major offenses. It emphasizes that how one treats others and performs rituals like prayer and charity are reflections of the spiritual state of one's heart, and that denying accountability in the afterlife hardens the heart against human compassion. The overall message is that religious and social duties in Islam are interlinked.
Scientific biological reasons (support and locomotion)
The document contains 17 questions and answers about biological concepts related to support and locomotion. It discusses why wilting occurs, how earthworms move, how exoskeletons provide support and protection, how cardiac muscles are unique, and how locomotion can be caused by water. The questions and answers cover a range of topics including plant responses, cell structure, skeletal systems, muscle function, and locomotion in different organisms. The document serves as a reference for biology textbooks on these concepts.

Know Biology With Scientific Reasons (homeostasis)
This document discusses homeostasis and the key physiological processes that contribute to homeostasis: osmoregulation, excretion, and thermoregulation. It presents these three processes as working together in an interconnected system to maintain homeostasis. Osmoregulation involves regulating water and solute concentrations, excretion eliminates nitrogenous wastes, and thermoregulation controls body temperature. The integrated functions of osmoregulation, excretion, and thermoregulation work to establish and preserve homeostasis in the body.
IMPACT OF CLIMATIC PARAMETERS ON PATHOGEN, INSECT PESTS AND CROP PRODUCTIVITY
Plant diseases occur in all parts of the world where plants grow. For a disease to occur and to develop optimally, a combination of three factors must be present. susceptible plant, infective pathogen and favorable environment.

Homeostasis In Mammals Ar
Homeostasis is the process by which organisms regulate their internal environment to maintain a stable and constant condition. It involves negative feedback mechanisms to correct changes and keep conditions within a narrow range. Key homeostatic processes in mammals include thermoregulation to maintain body temperature, osmoregulation of water and mineral levels by the kidneys, and regulation of blood glucose levels by the liver and pancreas.
Homeostasis its control mechanism
Homeostasis refers to the tendency of organisms to maintain stable internal conditions. In plants, homeostasis is achieved through processes like osmoregulation, thermoregulation, and excretion. Osmoregulation allows plants to regulate water levels through the opening and closing of stomata controlled by guard cells. Thermoregulation enables plants to adapt to low and high temperatures through changes to cell membranes and metabolic processes. Excretion removes excess water, oxygen, carbon dioxide, and ions from plants. Together these mechanisms maintain stable conditions internally to support plant health.
Additional biology revision guide
- Cells in both plants and animals contain organelles like the nucleus, cytoplasm, mitochondria, and ribosomes that allow the cell to carry out essential functions. Plants cells also contain chloroplasts for photosynthesis and a cell wall and vacuole.
- Photosynthesis uses carbon dioxide, water, and light energy to produce glucose and oxygen. Excess glucose is stored as starch. The rate depends on temperature, carbon dioxide levels, and sunlight.
- Energy flows through ecosystems as organisms consume biomass. Less energy is available at each trophic level due to the need for movement, maintaining body temperature, and other processes.
Homeostasis
Homeostasis refers to the maintenance of a constant internal environment in the body, keeping factors such as temperature, water concentration, and glucose levels stable despite changes in the external environment. This allows cells to function efficiently and prevents damage. Endothermic animals like mammals and birds internally regulate their body temperature, while ectothermic animals like reptiles rely on external temperatures. The skin plays an important role in homeostasis through its structure - the epidermis contains cells that protect the body and produce melanin and keratin, while the dermis contains sweat glands, blood vessels, and nerves that help regulate temperature.
Peter Shepherd Thermoregulation
The document discusses mechanisms for regulating body temperature in organisms. It explains that most cells function best between 30-40°C and that organisms have evolved various mechanisms to maintain an optimal internal temperature. These include insulation, vasoregulation of blood flow, sweating, shivering and behavioral adaptations. The hypothalamus plays a key role in sensing temperature changes and initiating responses. Mitochondria couple ATP production with heat generation. Brown fat contains uncoupling proteins that allow heat production without ATP generation.

Homeostasis
This document summarizes homeostasis and thermoregulation in animals. It discusses how regulators like mammals modify their internal environment through homeostasis, while conformers' internal environment changes with the external environment. Both regulation and conforming require energy, but regulation is more energy exhaustive. The document also describes temperature regulation in different groups of animals from ectotherms to endotherms. It explains the four processes of heat transfer and how different animals employ insulation, evaporative cooling, and behavioral adaptations to regulate their body temperature.
Overview of homeostasis & excretion
Homeostasis and excretion are related processes where homeostasis refers to maintaining a constant internal environment and excretion refers to removing metabolic waste products. The skin, lungs, liver, and kidneys are organs that help maintain homeostasis by regulating processes like temperature, water balance, and removal of toxins. The skin specifically regulates temperature through blood flow, sweat glands, and erector muscles in the dermis and helps remove some waste through sweat.
How do organisms maintain body temperature
There are four main means of heat transfer relevant to organisms: conduction, convection, radiation, and evaporation. Organisms regulate their body temperature using various strategies that depend on whether they are ectothermic or endothermic. Ectotherms rely on external factors to regulate temperature while endotherms generate their own body heat through high metabolism. Behavioral adaptations also allow some organisms to effectively control their body temperature.
1. animal form and function. animal form and function. animal form and function
This document discusses animal form and function at different levels of biological organization. It covers topics like anatomy, physiology, bioenergetics, homeostasis, thermoregulation, and adaptations like torpor and acclimatization. The key points are:
1) Animal form is shaped by natural selection to fit its function and environment over many generations. Its structure at different levels from cells to organ systems allows it to interact with its environment.
2) Bioenergetics examines how animals obtain and use energy from food. Having the right surface area to volume ratio and internal structures allows efficient exchange of materials in multicellular organisms.
3) Homeostasis and thermoregulation allow animals to maintain stable internal conditions
Adaptation_to_hot_climate_-_Copy.pptx
There are several physiological and behavioral adaptations that allow animals to survive in hot climates. Physiologically, animals can increase blood flow to the skin to dissipate heat through sweating or panting. They also tend to have shorter limbs and smaller bodies to reduce surface area and heat loss. Behaviorally, many animals are only active at night or bury underground to avoid heat during the day. Some animals can also enter a state of estivation like hibernation to lower their metabolism and tolerate higher temperatures.

This document discusses the basic principles of animal form and function. It covers several topics:
- How animals exchange materials with their environment through surfaces like skin or gills, and how body shape affects this.
- The four main types of tissues - epithelial, connective, muscle and nervous tissue.
- Homeostasis and how animals regulate internal conditions through feedback mechanisms even when the external environment changes.
- Thermoregulation as an example, how endothermic and ectothermic animals regulate their body temperatures using various physical and behavioral adaptations.
- How an animal's size, activity level and environment influence its energy requirements and metabolic rate. Smaller animals generally have higher metabolism per gram.
Excretory system --CynthiaC.
This document provides an overview of excretory systems and homeostasis in animals. It discusses the key components and functions of excretory systems, including osmoregulation, thermoregulation, and adaptations for living in different environments like marine, freshwater, and terrestrial settings. Key concepts covered include open vs closed circulatory systems, ectotherms vs endotherms, the roles of the kidney and nephrons, and how different animals regulate water balance and osmolarity.
Homeostasis
Homeostasis refers to the process by which organisms regulate internal conditions to maintain a stable and constant environment. Negative feedback loops play an important role in homeostasis, as the response works to remove or reduce the stimulus to bring the regulated factor back to its normal range. Thermoregulation, the ability to maintain a stable body temperature, is an important example of homeostasis that allows for optimal biological functioning across different temperatures. Both behavioral and physiological mechanisms enable endothermic and ectothermic organisms to regulate their body temperatures.
Cryopreservation
Germplasm refers to the genetic material of an organism. This document outlines methods for conserving plant germplasm, specifically cryopreservation which involves freezing plant tissues in liquid nitrogen. The key steps in cryopreservation include selecting suitable plant material, pre-freezing treatments using techniques like preculture or desiccation, freezing the material, storing it in liquid nitrogen, thawing it, and assessing viability. Cryopreservation allows for long-term storage of plant genetic resources and clonal propagation of plant varieties.
thermoregulatory machanism
The human body maintains a constant internal temperature of around 37°C through thermoregulation. The hypothalamus acts as the thermostat, monitoring internal temperature and triggering physiological responses like sweating or shivering to increase or decrease heat loss from the skin. When body heat production exceeds heat loss to the environment through conduction, convection, evaporation and radiation, core temperature rises, while imbalance in the other direction causes core temperature to fall. Strenuous exercise can challenge this system by greatly increasing heat production, requiring enhanced cooling to prevent overheating.
Body design
This chapter discusses how physical laws and the environment constrain animal size and shape. It introduces key concepts around form and function relationships in animals. These include how different tissues (epithelial, connective, muscle, and nervous) relate to an animal's functions. The chapter also covers bioenergetics and how animals obtain and use energy. A major topic is homeostasis, how animals regulate internal conditions, comparing endothermic and ectothermic strategies. Thermoregulation mechanisms like insulation, circulation and behavior are examined.
Skin and temperature
The document discusses the structure and functions of the skin and its layers. The skin consists of three main layers - the epidermis, dermis and subcutaneous layer. The epidermis is the outermost layer and provides protection against water loss and microorganisms. Below the epidermis lies the dermis, which contains hair follicles, sweat and sebaceous glands, nerves and blood vessels. The innermost layer, the subcutaneous layer, consists of adipose tissue and insulates the body.

Why Psychological Safety Matters for Software Teams - ACE 2024 - Ben Linders.pdf
Psychological safety in teams is important; team members must feel safe and able to communicate and collaborate effectively to deliver value. It’s also necessary to build long-lasting teams since things will happen and relationships will be strained.
But, how safe is a team? How can we determine if there are any factors that make the team unsafe or have an impact on the team’s culture?
In this mini-workshop, we’ll play games for psychological safety and team culture utilizing a deck of coaching cards, The Psychological Safety Cards. We will learn how to use gamification to gain a better understanding of what’s going on in teams. Individuals share what they have learned from working in teams, what has impacted the team’s safety and culture, and what has led to positive change.
Different game formats will be played in groups in parallel. Examples are an ice-breaker to get people talking about psychological safety, a constellation where people take positions about aspects of psychological safety in their team or organization, and collaborative card games where people work together to create an environment that fosters psychological safety.

Proposal: The Ark Project and The BEEP Inc
1.) Introduction
Our Movement is not new; it is the same as it was for Freedom, Justice, and Equality since we were labeled as slaves. However, this movement at its core must entail economics.
2.) Historical Context
This is the same movement because none of the previous movements, such as boycotts, were ever completed. For some, maybe, but for the most part, it’s just a place to keep your stable until you’re ready to assimilate them into your system. The rest of the crabs are left in the world’s worst parts, begging for scraps.
3.) Economic Empowerment
Our Movement aims to show that it is indeed possible for the less fortunate to establish their economic system. Everyone else – Caucasian, Asian, Mexican, Israeli, Jews, etc. – has their systems, and they all set up and usurp money from the less fortunate. So, the less fortunate buy from every one of them, yet none of them buy from the less fortunate. Moreover, the less fortunate really don’t have anything to sell.
4.) Collaboration with Organizations
Our Movement will demonstrate how organizations such as the National Association for the Advancement of Colored People, National Urban League, Black Lives Matter, and others can assist in creating a much more indestructible Black Wall Street.
5.) Vision for the Future
Our Movement will not settle for less than those who came before us and stopped before the rights were equal. The economy, jobs, healthcare, education, housing, incarceration – everything is unfair, and what isn’t is rigged for the less fortunate to fail, as evidenced in society.
6.) Call to Action
Our movement has started and implemented everything needed for the advancement of the economic system. There are positions for only those who understand the importance of this movement, as failure to address it will continue the degradation of the people deemed less fortunate.
No, this isn’t Noah’s Ark, nor am I a Prophet. I’m just a man who wrote a couple of books, created a magnificent website: http://www.thearkproject.llc, and who truly hopes to try and initiate a truly sustainable economic system for deprived people. We may not all have the same beliefs, but if our methods are tried, tested, and proven, we can come together and help others. My website: http://www.thearkproject.llc is very informative and considerably controversial. Please check it out, and if you are afraid, leave immediately; it’s no place for cowards. The last Prophet said: “Whoever among you sees an evil action, then let him change it with his hand [by taking action]; if he cannot, then with his tongue [by speaking out]; and if he cannot, then, with his heart – and that is the weakest of faith.” [Sahih Muslim] If we all, or even some of us, did this, there would be significant change. We are able to witness it on small and grand scales, for example, from climate control to business partnerships. I encourage, invite, and challenge you all to support me by visiting my website.
