“Nothing in biology makes sense except in the light of evolution”, Theodosius Dobzhansky. Evolution is a key unifying principle in biology. Judgment Day: Intelligent Design on Trial is NOVA documentary on the case of Kitzmiller v. Dover Area School District. In November 2004, the local school board in the small town of Dover, Pennsylvania ordered their high school science teachers to read a statement about Intelligent Design to biology students. Intelligent Design is a statement that suggested an
crowded area and must be able to travel to a less crowded area to live. The biological processes of photosynthesis and aerobic respiration allow him to do this. Because of these two processes, energy is given to the kinetosome, which then allows the flagellum of Mr. Euglena to move him to a less crowded area. Mr. Euglena is aware that he must move to less crowded area in order to live. However, he waits patiently for the sun to gradually move higher in the sky. He believes that if he waits for enough
Prokaryotic Cells All living things are made of cells, and cells are the smallest units that can be alive. Life on Earth is classified into five kingdoms, and they each have their own characteristic kind of cell. However the biggest division is between the cells of the prokaryote kingdom (monera, the bacteria) and those of the other four kingdoms (animals, plants, fungi and protoctista), which are all eukaryotic cells. Prokaryotic cells are smaller and simpler than eukaryotic cells, and
The video focuses on the debate and court room trial about the 2 major points of view about how humans, or any other living organisms in general, were created. It tells us about the argument that began as a result of a rule that was implemented in a high school in Dover, Pennsylvania. The rule dictated that a subject on Intelligent Design must be included in the curriculum of the high school students enrolled there. According to Intelligent Design, some of the features of living organisms are too
Abstract The purpose of this study is to better understand the implications that different levels of pH have on development of sea-urchin larvae. Many sea creatures reproduce and flourish in certain water qualities and reproduction can be hindered if levels are not maintained. Sea Urchins are important in understanding not only urchin cells, fertilization, and heredity but can also be linked directly to humans. If we can apply our understanding of urchin reproduction we can better understand how
This statement if for the MU PREP program to further elaborate on my laboratory experiences. My very first laboratory experience was with Dr. Rolf Joerger at the University of Delaware’s Townsend Hall food microbiology laboratory through the Nation Science Foundation - EPSCoR Progrram, there I also helped out some other principle investigators around the department occasionally as need. I came in, in the midst of ongoing research pertaining to the acid tolerance resistance of salmonella serovors
photosynthesis, which would help them diatom because it needs photosynthesis to live. Those are some of the morphological adaptations that diatoms have evolved to help them maintain a planktonic existence. Dinoflagellates have a pair of flagellum, transverse flagellum, that are wound up around the body and then when whipped in a wavelike fashion causes the cell to go in a spinning motion, giving it a forward propulsion. This helps the dinoflagellates keep their planktonic existence because it can help
Proteus Mirabilis Life History: Proteus mirabilis is part of the normal flora of the human gastrointestinal tract. It can also be found free living in water and soil. When this organism, however, enters the urinary tract, wounds, or the lungs it can become pathogenic. Proteus mirabilis commonly causes urinary tract infections and the formation of stones. Microbiological Characteristics: Proteus mirabilis is part of the Enterobacteriaceae family. It is a small gram-negative bacillus
Lab Exercise 6: The Ubiquity of Bacteria Purpose: The purpose of Lab Exercise 6: The Ubiquity of Bacteria is to introduce to the microbiology student, the proper techniques for acquiring bacteria cultures from natural sources and appreciate that bacteria are found everywhere. Equipment/Tools: 1-test tube of nutrient broth, 1-sterile swab, 1-petri dish with nutrient agar, 1-petri dish with sheep’s blood, 1-incubator, 1-sharpie pen and a cough. Observations/Results: One test tube incubated for 120
A cell is the smallest functional unit of an organism, that has a structure. The parts of a cell vary in sizes, functions, and shapes. Cells are usually microscopic and are either eukaryotic or prokaryotic. Eukaryotic cells contain many organelles surrounded by a cellular membrane. Animal and plant cells are eukaryotic. Prokaryotic cells do not have a nucleus and many of the other organelles found in eukaryotic cells. Single cell bacteria are an example of a prokaryotic cell. In our cell project
Intelligent design proposes a serious scientific challenge to evolution. Specifically Michael Behe looks at the processes of cells such as his example of the E. coli bacterium which propels itself with its own ‘flagellum’ (rotating tail). From there he expands by making the point that the flagellum needs to be complete to be of any use; this is where he coined the idea of the Irreducible complexity concept. Simply he states that the removal of any one of the parts from a complex system the whole system
Auxin is one of the phytohormones. Auxin is basically represented as indol-3-acetic acid (IAA) in plants. It is important in regulating various growths and formation processes (Kefeli & Kalevitch, 2003). Auxin is essential in many vital tasks in plants. Therefore, plants which are unable to produce IAA do not exist. The role of auxin is described by “short distance activity” as a morphogen (Friml, 2003). The term morphogen was probably first being used by the British mathematician Alan Mathison Turing
different layers such as a capsule, cell wall and Plasma Membrane. This gives the cell lots of protection and makes it live longer. It has little sticks that come out of the sides called Pilli. It has an almost tail like feature called the Bacterial Flagellum, this helps the cell move and protects it from bacteria that could harm
Trichomonas Vaginalis T. vaginalis is a pear-shaped organism that moves itself with four whip-like flagellas that protrude from its front end. A fifth flagellum attached to a flowing membrane that extends rearward. T. vaginalis is a non civilized eukaryotic organism that is in most respects similar to other eukaryotes, but its energy metabolism bears a stronger resemblance to that of anaerobic bacteria. Trichomoniasis is a very common sexually transmitted disease (STD) that is caused by infection
Since the Computer Age, researchers have striven to make all components smaller. For example, the transistor started as large vacuum tubes originally used for phone line amplification in 1947. Since then, miniaturization steps have made transistors as small as 45 nm. Furthermore, materials that have certain properties in bulk have vastly different properties in the nano-scale. With constant new miniature electronics and novel nano-materials, scientists are experimenting with radical new designs for
• BIO-112-IT1-S-14 Topic 7 Module 2 Exam - topics for essay and sho... Viruses. 1. Why are viruses not living organisms? Pg325 Viruses are not considered living organisms because they have a single viral structural. This means viruses are not cells because they have no nucleus, organelle, or cytoplasm, and no genetic material. Having none of these characteristics viruses cannot be considered a living cell because they do not metabolize, respond to stimuli or reproduce on their own. They have to
enzymes that help convert food material into adenosine triphosphate (ATP), which can be used directly by the cell as an energy source. Mitochondria tend to be concentrated near cellular structures that require large inputs of energy, such as the flagellum. The role of the mitochondria is very important in respiration. In the presence of oxygen, pyruvate or fatty acids, can be further oxidized in the mitochondria. Each mitochondrion is enclosed by two membranes separated by an intermembrane space
organelles and an outer cell wall. The outer cell wall is strengthened by peptidoglycan, which protects the bacteria from collapsing or bursting. Some bacteria have the means to move. The reason they’re able to move is because they have flagella. Flagellum is a long slender tail-like structure. Virus’s structure is less complex than the structure of bacterium. All viruses are composed of two parts: the outer capsid, and the inner core. The outer capsid is made of protein subunits, and the inner core
Intelligent design also referred to as ID is a concept that has its early origins from 4th century BC in the works Timaeus by Plato were he describes a supreme wisdom and intelligence as the creator of the cosmos. In the Metaphysics Aristotle furthers developed the idea of a natural creator of the cosmos. One of the most famous ideas for intelligent design today comes the 13th century where Thomas Aguinas described the concept of design as the fifth of five proofs for the existence of God in his
Yeast is a type of a fungus, and Lactobacillus acidophilus is a type of bacterium. First of all, yeast is a unicellular fungus that consists of the single oval-shaped cell. It is capable of converting sugar into carbon dioxide and alcohol. The word ‘yeast’ was originated from the Old English word ‘gist’ and ‘gyst’. Also from the Indo-European word meaning ‘boil’, ‘foam’ or ‘bubble’. Yeast cell is made up with nucleus, which contains genetic codes for enzymes for the respiration, Mitochondria (a.k
