Biology Evolution, Energy, Information, And Systems

Biology, the study of life and living organisms, is complex and encompasses a multitude of theories and ideas. In AP Biology, the fourth unit covered was genetics. Chapters 11, 12, 13, 14, 15, 16, and 18 in the textbook, Campbell’s Biology in Focus, not only discusses the four main ideas of biology: evolution, energy, information, and systems, but it also gives examples of each in order to help guide the reader’s understanding of the concepts. The first big idea of AP Biology is: â€Å"the process of evolution drives the diversity and unity of life.† Chapter 11 in the textbook encompasses this main idea through discussing alleles, phenotypic variations, and genetic variation. An individual receives two alleles, different versions of a†¦show more content†¦Another factor affecting populations is genetic diseases and disorders. X-linked recessive diseases most often occur and males (which they inherited from their mothers), since men only have one X chromo some and a single recessive gene, without a dominant one to cover it up, will be expressed. For example, hemophilia, a condition in which the ability of blood to clot is severely reduced, was spread to royal families across Europe, including the thrones of Britain, Germany, France, Russia, and Spain, after Queen Victoria, a carrier of the disease, passed it to many of her descendants. The AP Biology course’s second key concept is: â€Å"biological systems utilize energy and molecular building blocks to grow, reproduce, and to maintain homeostasis.† One of the main points encompassed in this idea is cell differentiation, the process by which cells specialize in structure and function, highlighted in chapter 16. Cell specialization is an overarching concept that connects to the idea that the coordination of specific events is necessary for the normal development of an organism. In an embryo, cytoplasmic determinants, material substances in an egg that influence the course of development, receive signals from the environment and neighboring cells. The uneven distribution of these molecules creates gradients that determine the orientation, such as the anterior and posterior, of the organism.Show MoreRelatedEvolution Of A Common Single Celled Origin1278 Words   |  6 PagesIn the course of AP Biology, there are four â€Å"Big Ideas†. The first one is â€Å"The process of evolution drives the diversity and unity of life†. The second is â€Å"Biological systems utilize free energy and molecular building blocks to grow, to reproduce and to maintain dynamic homeostasis†. The third is described as, â€Å"Living systems store, retrieve, transmit and respond to information essential to life processes.† And finally the four is â€Å"biological systems interact, and these systems and their interactionRead MoreBiology : The Scientific Stud y Of Life1617 Words   |  7 PagesBiology is defined as the scientific study of life. (Campbell Essential Biology) Whether or not something is â€Å"alive† is recognized by their ability to perform actions that living things do. There are seven main properties associated with life, we refer to these as; The Properties of Life. Order, regulation, growth and development, energy processing, response to the environment, reproduction, and evolution; these properties are the basis in which we use to determine whether or not something is â€Å"alive†Read MoreThe And Evolution Between Creationism And Creationism1023 Words   |  5 Pagestime in the biology classroom any time soon. The Ohio standards for science include evolution as a core component mandating that biology teachers incorporate natural selection and the history of life on earth as part of the curriculum. One strategy, presented by the National Center for Science Education is teaching the information and the po sitions that are held by people as a continuum. According to Eugenie Scott, many Americans consider the controversy between creationism and evolution as existingRead More Evolution Essay597 Words   |  3 PagesEvolution Evolution is a complex process by which the characteristics of living organisms change over many generations as traits are passed from one generation to the next. Many scientists agree on that concept. They have been trying to develop this theory over hundreds of years to make it reasonable and beliveable to people. But is evolution the reason that humans are on earth? People that are not quite religious and have little faith in God believe in evolution.

There are two main definitions of a system, an implicit and an explicit phrase, with the explicit phrase being used in system thinking by organizations. The definition refers to a system as being a collection of highly integrated parts or subsystems that attain a specific goal, through inputs that are processed into precise outputs. And thus if a part of this highly-linked system is changed, the overall system is also changed.

Molecular docking [2–4] is one of these in silico techniques. Docking is a method which predicts preferred orientation (on the basis of binding energy) of one molecule to the second to form a stable complex. In the field of drug design, first molecule is usually protein/enzyme/DNA and the second one is small organic molecule/small peptides
