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 date they experimented with the theory, and a sentence or two to describe the theory.

Bioenergetics: Antoine-Laurent Lavoisier Late 18th century
Chemistry of Life was placed in a context of a larger understanding of chemistry and energetic.

Biological classification: Carolus Linneaus late 18th century
Organisms are classified according to their similarities and differences.

Cells: Matthias Schleiden and Theodor Schwann beginning of the 17th century
All organisms are made of cells and all cells are made of preexisting cells.

Ecosystems: no identifiable parent but a group of people- 20th century

Organisms interact with each other and other things in their environment and changes in their environment change other things as well. Everything works together to keep that environment going right.

Evolution by natural selection: Charles Darwin- mid 19th century Species are able to evolve over time and only the strongest will be able to do so. The strongest of the species is the one that continues to live and produce offspring while the weaker ones don’t get the mates and die off getting rid of that “bad gene”

Homeostasis: Claude Bernard mid 19th century
Organisms function best when they have a stable internal environment despite the varying external environment.

Inheritance: Gregor Mendel-…...

...Due date: November 14, 2012 Biology 102: Stem Cells Stem Cells in Cancer Every day many people suffer from different kinds of cancers. Many of them suffer from Lung cancer, Skin cancer, or even cancer in the brain (tumor). However, many of them don’t survive because the fact is that many times it’s too late to save them with treatment that accurate today. Recently, there has been new research about cancer that could actually save more people from cancer. Michael Clarke and Robert Weinberg found new developments in cancer. They discovered that Stem Cells found in human’s bodies could actually save people who are suffering from cancer. This new development is a new idea that needs to be developed further. If Doctors can prove that Stem Cells could help cure cancer, many people who suffer from cancer could have hope to live a longer lives. It’s such a disgrace to see people die from cancer (about 26 % of US Population) especially young people. We cannot choose who will get cancer, when and if they are still going to live. That is why everyday more and more doctors are always researching and trying to find a ways for new developments treatments Stem cells were being developed in 1997 by John Dick, which he found in Leukemia. Stem Cells were difficult to find because not many doctors know how to spot them. Stem cells are self-renewal, which means that they are always dividing and give us results of identical stem cells. Although this new development could be a good......

...trains the heart to pump more blood per stroke. Exercise also trains the muscles to use oxygen more efficiently, taking even more stress off the heart. A resting heart rate above gender averages could mean that the heart is weak or that the body is not using oxygen efficiently. The results were reliable because all scientific procedures were followed during the experimentations. Better still, a well improved result would been attained if factors that could affect pulse rate such as age, sex temperature were considered, for instance considering different age groups and also both male and female sexes.

...not be effective in humans. However, the thyroid glands secrete hormones that increase metabolism to generate heat. Also when it is cold some muscles cause you to shiver in order to create heat. Conclusion I’ve learned that the key is homeostasis means “staying the same”. This is valuable. Our body temperature is an important factor to our being. This is the key to remaining healthy. Our receptors monitor the environment. The control center formulates the response. Nerve impulses are output and then effectors then carry out the change. Our body has a natural sense to stay warm. In turn, our body also knows how to react to its environment. This is the cycle. Reference: Ireland, K. A. (2012). Visualizing human biology (4th ed.). Danvers, MA: Wiley....

...rate of proliferation is relatively slow as the daughter cells progressively differentiate as they travel up the walls of the crypt to replace the Absorptive cells that have been removed through mechanical damage (ASCC 2011; Lyons,I 2011). These stem cells play a vital role in medical research because they have the ability to heal and disperse to any part of the body to self-heal (ASCC 2011; Lyons,I 2011). Currently, Umbilical cord stem cells are being used to treat a several blood disorders and conditions such as anaemia, autoimmune diseases and leukaemia. They are mainly used in children, but are slowly being introduced in the treatments of adults. Stem Cell research is also being developed to improve our understanding of fundamental processes in biology and contribute to new methods in the treatments of diseases for example; stem cells can be derived from patients with known genetic disorders, allowing researchers to study the disease process therefore allowing the testing of different medications and treatments (NHMRC 2011). Stem cells have the ability to self-heal and renew the body. The ability for the use of stem cells in medicine is only being discovered, however they have been used in treating blood disorders and conditions such as anaemia. Although this is just the beginning and exciting times lie ahead in the field of stem cell research. References Australian Stem Cell Centre., 2011. Fact Sheet 1, What are Stem Cells.......

These sub-theories require continued elaboration, particularly in light of molecular biology, to answer openended questions concerning the mechanisms of evolution in all five kingdoms of life. Introduction Physicists and chemists investigate the properties and interactions of objects, such as electrons, photons, and atoms, which are physically uniform and invariant in their characteristic traits and behavior. Accordingly, a single experiment adducing the properties of a single entity (e.g., electron or proton) can be used to extrapolate the properties of all comparable entities in the universe.

...Biology From Wikipedia, the free encyclopedia For other uses, see Biology (disambiguation). Biology deals with the study of the many varieties of living organisms. Clockwise from top left: Salmonella typhimurium, Phascolarctos cinereus, Athyrium filix-femina, Amanita muscaria, Agalychnis callidryas, and Brachypelma smithi Biology is a natural science concerned with the study of life and living organisms, including their structure, function, growth, origin, evolution, distribution, and taxonomy.[1] Biology is a vast subject containing many subdivisions, topics, and disciplines. Among the most important topics are five unifying principles that can be said to be the fundamental axioms of modern biology:[2] 1. Cells are the basic unit of life 2. New species and inherited traits are the product of evolution 3. Genes are the basic unit of heredity 4. An organism regulates its internal environment to maintain a stable and constant condition 5. Living organisms consume and transform energy. Subdisciplines of biology are recognized on the basis of the scale at which organisms are studied and the methods used to study them: biochemistry examines the rudimentary chemistry of life; molecular biology studies the complex interactions of systems of biological molecules; cellular biology examines the basic building block of all life, the cell; physiology examines the physical and chemical functions of the tissues, organs, and organ systems of an organism; and......

We will examine, using experiments, observations, simulations, and quantitative approaches, processes that cause evolution in populations and the dynamics involved in interspecific relationships in communities and ecosystems. After completing a semester of this lab, students should be able to: • Describe the process of evolution and the processes that shape the distribution and dynamics of ecological systems. • Analyze and display data using Microsoft Excel and appropriate statistical tests. • Generate and test hypotheses using the scientific method and careful laboratory techniques. • Select relevant primary literature on a given topic and integrate information from multiple primary sources into a written scientific lab report, using appropriate citations. • Conduct an experiment, collect and analyze data, and write a scientific lab report according to the conventions of biology, using a process of staged writing and revisions.
