Fundamentals of Biology Essay

You are beginning a Journey in the world of biology. Completing this worksheet will prepare you with the background knowledge necessary for understanding this world! What Are the Major Theories of Biology? The major theories of biology have been tested over years and provide information helping you to understand the science of biology. For each theory, list the name of the person or persons known for scientifically testing each theory, the approximate ate they experimented with the theory, and a sentence or two to describe the theory.

Bioengineering: Antoine-Laurent Lavisher, late 18th century… Helped to place the chemistry of life into the context of a larger understanding of chemistry and energetic. Biological classification: Carol’s Linnaeus, late 18th century… This evolutionary approach is how we organize and classify organisms today. Cells: Matthias Schlemiel and Theodore Schuman, 17th century… The cell is the smallest Unit capable of exhibiting all of the characteristics of life. Ecosystems: 20th century… His one has no readily identifiable person rather it was forged More slowly by a widely separated and diverse group of specialists. This concept recognizes that organisms do not exist alone, but are part of populations of similar beings, communities comprising many different living things, and environments Evolution by natural selection: Charles Darwin, 1859… This theory has two parts: natural selections and species. Homeostasis: Claude Bernard, mid-19th century… Organisms function best when heir internal conditions are maintained within rather narrow limits and that organisms tolerate widely varying external conditions by maintaining stable conditions internally-?a condition known as homeostasis Inheritance: Gregory Mendel, 20th century… Mendel proved that traits, or characteristics, of organisms pass from one generation to the next by hereditary doctors which are now call De genes. What Are the Characteristics of a Living Organism Ten characteristics distinguish an object or thing from an actual living organism.

All 0 characteristics must be present simultaneously for something to be considered living. The following table lists one of the ten characteristics that make up a living organism. Fill in the remaining characteristics. Characteristics of a Living Organism I 1. Composed of one or more cells I 2. Highly organized, complex entities I 3. Contain a blueprint of their characteristics (a genetic program) and use energy I 5. Carry out and control numerous chemical reactions I 6. Grow in size and change in appearance and abilities I 7. Maintain a fairly constant internal environment I . Reduce offspring similar to themselves I 9. Respond to changes in their environments I 10. May evolve into new types of organisms I What Is Scientific Method? | 4. Acquire Scientific method is a way of conducting experiments that allows scientists to compare results and revise in their experiments to further research and increase knowledge in specific areas. Understanding scientific method helps you to recognize and evaluate the facts and theories in this course. Write a brief description of each step in scientific method. 1 .

Observation: a new way of looking at things, or the astute realization that the natural world is at odds with ideas that are currently accepted. Also observations lead to questions. 2. Questioning: Scientific questions are those that can be answered by experimentation or by direct observation of the material universe. 3. Hypothesis: A hypothesis is conjecture, a possible answer to the how or why questions that have been posed. 4. Testing: testing is the activity that occupies most of a working scientist’s time. 5. Explanation: a scientific explanation is a mature hypothesis.
