major cause of disease because chronic stress causes long-term chemical changes. He observed that the body would respond to any external biological source of stress with a predictable biological pattern in an attempt to restore the body’s internal homeostasis. This initial hormonal reaction is your fight or flight stress response - and its purpose is for handling stress very quickly! The process of the body’s struggle to maintain balance is what Selye termed‚ the General Adaptation Syndrome. Pressures

Why a plant is a living thing and a rock isn’t Cells All living things and organisms have cells. Cell is a collection of living matter. Any living thing that is made up of a single cell is a unicellular organism. The organism that is most familiar is a multicellular organism for example animals and plants. A rock unlike a plant or an animal does not any cells that can grow‚ reproduce‚ or respond to the environment. Reproduction All organisms can make new organisms through a process called reproduction

organsims live. 2. List the 5 major features common to all living things. Made up of cells Evolution (change over time) Growth and Development (Cell divison/DNA) Need for energy and raw materials (Meatabolism) Response to environment (homeostasis) 3. List 2 different ways living organisms accomplish each of the 5 features above. (the focus here is to recognize how living things differ from one another) We divide Earth’s biodiversity into broad groups based on traits such as having a nucleus

Introduction: The question investigated in this lab was which drugs have the greatest and least affect on the pulse of the Lumbriculus variegates. Ethanol will cause the worms to become inactive‚ caffeine will cause the worms to become overactive‚ and nicotine will cause the worms to become more active. Lumbriculus variegatus is also known as black worm. This small species of worms currently lives in North America and Europe within marshes and ponds. They survive by eating microorganisms and organic
Premium Standard deviation Heart rate Physiology
There are four components in the negative feedback system. Controlled variable is a physical or chemical property that may vary and must be controlled to maintain homeostasis. An example of a controlled variable is body temperature. A sensor also known as the receptor monitors the value of the controlled value and sends the information to the control center. The control center then receives the information from the sensor

Cushing’s Syndrome Cushing’s Syndrome is a condition that results from chronic exposure to excessive amounts of glucocorticoids circulating in the blood stream for an extended period of time. The disease was first reported by Harvey Cushing over one hundred years ago‚ yet the condition still plagues endocrinologists today. Reasons for this difficulty include the vast amount of often vague symptoms that the syndrome presents‚ most of which are found in a plethora of other conditions as well‚ combined

Start with a some DNA‚ or RNA if you are so inclined‚ mix in a simple matrix‚ fold the mixture into a protein coat‚ and pour into a plasma membrane. Could this be the recipe for elementary life? Viruses are one of the simplest forms of organized organic material to arise in evolution. They are infamously the most efficient at reproducing while simultaneously eliminating competition which are two of the most fundamental characteristics of life. Despite these remarkable abilities‚ most biologists are

WEEK 1: AN INTRODUCTION TO HUMAN ANATOMY & PHYSIOLOGY 1. Define the terms anatomy and physiology‚ and explain their relationship using an example of a human structure with its corresponding function. Anatomy is the study of the human body while physiology‚ is the study of how the body functions. For example‚ the cardiovascular system includes the heart‚ veins‚ and blood. The heart produces a controlled electrical shock that causes the heart to contort. This creates a pumping action that pushes
