In 2008, I taught this class first period, and several students would come in early and use the whiteboard to sketch out/outline/diagram things that they were trying to understand. These technology advances allowed theoretical and experimental research including internet publication of molecular biochemistry, biological systems, and ecosystems science. A student shall have one day to complete and turn in the work for each day the student is absent (i.e., in the event of a 3 day absence, the student has 3 days to complete and turn in the assignments) and may only earn 50% credit.

However, the medical theories of Hippocrates and his followers, especially humorism, had a lasting impact. Either alone or a combination of these energy sources caused reactions that produced complex organic compounds (including amino acids) from a mixture of ammonia (NH3), methane (CH4), water (H2O) and hydrogen (H2).
Phospholipids are amphipathic molecules, meaning that they present a polar portion and a nonpolar portion. 366-369, Crash Course: Ecosystem Ecology – Links In The Chain, Crash Course: Ecological Succession – Change Is Good, Bozeman: Biology – Unit 10: Ecology Environmental Matter Exchange (Water and Carbon cycles), Hippocampus, E, Energy Flow and the Water Cycle pp. Coacervates also allowed a selective flow of molecules across their membrane.
The history of biology traces the study of the living world from ancient to modern times. Assignments will not be accepted after they are collected at the beginning of the class period on the day they are due. Structure Function DNA, Quarter 3 The autotrophic hypothesis of the origin of life claims that the first living organisms on earth were producers of their own food, just like plants and chemosynthetic microorganisms. Evolution Math
Many of Theophrastus' names survive into modern times, such as carpos for fruit, and pericarpion for seed vessel. 30 – 38, Crash Course: That’s Why Carbon Is a Tramp, Bozeman – Biology – Unit 2: Chemistry of Life – Water a Polar Molecule http://www.youtube.com/watch?v=DVCYlST6mYQ&list=PL43285691048DAD00 If this link doesn’t work, search for it in You Tube. According to the heterotrophic hypothesis, the first living organisms were very simple heterotrophic organisms, that is, organisms that are not producers of their own food, which emerged from the gradual incorporation of organic molecules into small organized structures (the coacervates). Please refer to Origin of Life later in this this discussion. This hypothesis asserts that primitive life had only RNA as genetic material and structural molecules, and that it later turned into DNA and proteins. Apply the principles of evolution by natural selection to pre-biotic scenarios. 4th quarter practice 7

Crash Course: Biological Molecules – You Are What You Eat, Proteins I: Basic Structure: http://www.youtube.com/user/kristinagremski#p/u/6/KH-LQSr7rHs 359-363, 383-392, Crash Course: Population Ecology – The Texas Mosquito Mystery, Bozeman: Biology – Unit 10: Ecology Populations Human Impact, Hippocampus, E, Conservation Biology pp. [88], Wary of the potential dangers (particularly the possibility of a prolific bacteria with a viral cancer-causing gene), the scientific community as well as a wide range of scientific outsiders reacted to these developments with both enthusiasm and fearful restraint. Félix d'Herelle's isolation of bacteriophage during World War I initiated a long line of research focused on phage viruses and the bacteria they infect.
z State the position of virus and differentiate between virus and viroids. 1048-1057, Crash Course: The Reproductive System – How Gonads Go, Brain map site: http://www.bbc.co.uk/science/humanbody/body/interactives/organs/brainmap/, Nervous and endocrine system comparison: http://sites.google.com/site/rhscience7minivideos/home/nervous-endocrine-systems/stimulus-response p. 1011, Muscular/skeletal: http://sites.google.com/site/rhscience7minivideos/home/muscular-skeletal-systems, Digestive; http://sites.google.com/site/rhscience7minivideos/home/digestive-system pp. [14] In East Semitic cultures, the main medicinal authority was an exorcist-healer known as an āšipu. Pig Dissection for Dummies PP
[35], The discovery and description of new species and the collection of specimens became a passion of scientific gentlemen and a lucrative enterprise for entrepreneurs; many naturalists traveled the globe in search of scientific knowledge and adventure. Lavoisier and other physical scientists began to connect the animate and inanimate worlds through physics and chemistry. New disciplines developed rapidly, especially after Watson and Crick proposed the structure of DNA. [62] Soon after, cytologists (cell biologists) proposed that chromosomes were the hereditary material.
Class powerpoint notes can be accessed through my website below. Khan HardyWeinberg: http://www.youtube.com/watch?v=4Kbruik_LOo By the end of the 19th century the concept of enzymes was well established, though equations of chemical kinetics would not be applied to enzymatic reactions until the early 20th century. [81], The late 1950s to the early 1970s was a period of intense research and institutional expansion for molecular biology, which had only recently become a somewhat coherent discipline. Bozeman: Biology, Unit 2 Chemistry of Life: Proteins pp.
In a series of lectures and papers that made detailed comparisons between living mammals and fossil remains Cuvier was able to establish that the fossils were remains of species that had become extinct—rather than being remains of species still alive elsewhere in the world, as had been widely believed. Pig Dissection Word Bank There are no retests on unit tests. What I now call the Copenhaver Technique after its main practitioner is a GREAT way to digest material. It is believed that these structures may have been the precursors to cells. [86], Biotechnology in the modern sense of genetic engineering began in the 1970s, with the invention of recombinant DNA techniques. A pdf copy of this test is also in the EOC folder. Bozeman: Biology, Unit 4: Genetics:Advanced Genetics 3:10 – 7:45 for multiple alleles and polygenic traits pp.
The earth is believed to be approximately 4.5 billion years old. Pedigree Analysis 2: http://www.youtube.com/watch?v=ej2hFc8u_zQ&feature=fvwrel, Optional Khan Academy Videos [8], The ancient Mesopotamians had no distinction between "rational science" and magic.
The RNA world hypothesis is strengthened by the fact that RNA can play the role of a catalyst, like enzymes, and by discoveries that some bacteria have ribosomes made of only RNA without proteins attached to it. In 1953, Stanley Miller arranged an experimental apparatus that simulated the atmospheric conditions of primitive earth. It claims that this is the origin of mitochondria, which were aerobic bacteria engulfed by eukaryotic anaerobes during their primitive stages. This enabled worldwide access to better measurements, theoretical models, complex simulations, theory predictive model experimentation, analysis, worldwide internet observational data reporting, open peer-review, collaboration, and internet publication. By the 1880s, bacteriology was becoming a coherent discipline, especially through the work of Robert Koch, who introduced methods for growing pure cultures on agar gels containing specific nutrients in Petri dishes. He made countless observations of nature, especially the habits and attributes of plants and animals in the world around him, which he devoted considerable attention to categorizing. 55-56 Just select (or double-click) a question to share. Talk to and listen to someone you know who has been in this class. Thinkwell – Dihybrid Crosses: http://www.youtube.com/watch?v=s3dsDgnB6DY&feature=relmfu THIS MAY WELL BE YOUR BIGGEST TRANSITION FROM MIDDLE SCHOOL!! [47], Wallace, following on earlier work by de Candolle, Humboldt and Darwin, made major contributions to zoogeography.
than the other Crash Course one.
These percentages are subject to change by marking period as determined by the Biology Department. To actually decipher the code, it took an extensive series of experiments in biochemistry and bacterial genetics, between 1961 and 1966—most importantly the work of Nirenberg and Khorana. The Pillar of the Month in October is RESPONSIBILITY.

This ancient work was further developed in the Middle Ages by Muslim physicians and scholars such as Avicenna.
