A group of organisms of small size has been discovered which can be cultivated in indefinite series. The organisms form a well-defined group and have both relatively large and small forms. The smaller forms appear to be as small as vaccinia virus and from them the larger forms readily develop. Occurrence The organisms have been obtained from all samples of raw sewage so far examined from four London districts during the summer. They have not been detected in London tap-water, or faecal material from man, pig, rabbit, or rat. ...
Unit 1: How do living things stay alive?. In this unit students are introduced to some of the challenges to an organism in sustaining life. Students examine the cell as the structural and functional unit of life, from the single celled to the multicellular organism, and the requirements for sustaining cellular processes in terms of inputs and outputs. They analyse types of adaptations that enhance the organisms survival in a particular environment and consider the role homeostatic mechanisms play in maintaining the internal environment. Students investigate how a diverse group of organisms form a living interconnected community that is adapted to, and utilises, the abiotic resources of its habitat. The role of a keystone species in maintaining the structure of an ecosystem is explored. Students consider how the planets biodiversity is classified and the factors that affect the growth of a population. Area of study 1. How do organisms function?. Outcome 1 On completion of this unit the student ...
Immunoglobulins are made by white blood cells known as B cells (B lymphocytes). Any disease that harms the development or function of B cells will, therefore, affect the production of immunoglobulin antibodies. T cells, another type of white blood cell, may also be involved in immunodeficiency disorders. About 70 percent of immunoglobulin deficiencies involve B lymphocytes and 20-30 percent involve T lymphocytes. Another 10 percent may involve both B and T lymphocytes. Many of the infections that occur in children with immunoglobulin deficiency syndromes are caused by bacterial organisms or microbes. Certain of these invasive organisms form capsules when they enter the body, a mechanism used to confuse the immune system. In a healthy body with an adequately functioning immune system, immunoglobulin antibodies bind to the capsule and overcome the bacterias defenses. Streptococci, meningococci, and Haemophilus influenzae , organisms that cause diseases such as otitis media , sinusitis , pneumonia ...
modified with decent to adapt to their environment another statement at 100% conflict with any number of statements by leading evolutionists. Evolution has no direction, no purpose, no plan it is the product of random mutation at the genetic level giving rise to totally unplanned changes in the organisms form and function. The environment then is either hostile to or supportive of those changes and the organism is either as a species more reproductively successful or it is made extinct. In no sense does the organism adapt to the environment in fact the environment adapts it either to continued life or to death, as a species ...
With these matters in mind, what I wish to convey is that stem cells can obey various inputs in the terrestrial cogniscium. It is unclear precisely what the hierarchy of sources is, but we may imagine that up near the top of the local group is the Sun, the Earth, and the moon (as a force if not a cogniscium of its own). The Sun certainly comprises a cogniscium since it is intimately connected to every life form on Earth both by history and by actively existing transports. Thus, the organisms of Earth probably have the capacity to experience actually prophetic awareness and, where possible, understanding - related to opportunities, threats, and questions raised by changes in the broadest local scales of inputs. In other words, organisms form the distributed mind of a being whose basic character we are in no position to even begin to model - and, to make matters more complex, we are each, and in groups, instances of this being as well as participants. This means that our actions, thoughts, ...

Anthrax is a disease that is no stranger to the human race. It can be traced back to Biblical times and is the oldest known disease of animals. Moses mentions it in Exodus and so do Homer, Ovid, Pliny, and Virgil in their writings. Obviously, this disease has been around. It has many names, such as woolsorters disease, splenic fever, charbon in French, Milzbrand in German, and malignant pustule. Anthrax was the first infectious disease that a vaccine was found to be effective against by Louis Pasteur in 1881. The studies of Anthrax in the 18th century are the foundation for the science of bacteriology and immunology. Anthrax is an infectious disease caused by the organism Bacillus anthracis. In certain conditions, this organism forms virulent spores that are highly resistant and contaminate soil or other materials for years. Anthrax is most common in grass grazing animals such as cows and sheep but all animals can t get Anthrax. It can be passed on to a person who handles wool, hides, or carcass ...
Leaving aside the troublesome adjective, what is the modernism that the Altenburg meeting is meant to move beyond - or to use Pigliuccis preferred term, extend1? Between about 1920 and 1940, researchers such as the American Sewall Wright and the Englishmen Ronald Fisher and J. B. S. Haldane took Charles Darwins ideas about natural selection and Gregor Mendels insights into how traits pass from parents to offspring - which many biologists of the time believed antithetical - and fused them into a mathematical description of the genetic makeup of populations and how it changes. That fusion was the modern synthesis. It treats an organisms form, or phenotype, as a readout of its hereditary information, or genotype. Change is explained as one version of a gene being replaced by another. Natural selection acts by changing the frequency of genes in the next generation according to the fitness of phenotypes in this one. In this world view, the gene is a black box, its relationship to phenotype is a ...

Courtesy of: http://dels-old.nas.edu/oceans/oceans_and_human_health_part_2.shtml Introduction: This blog examines the relationship between the Hawaiian Bobtail Squid and a bioluminescent bacterium. The Hawaiian Bobtail squid acquires an enhanced ability to capture prey and avoid predators, while the bacterium receives key nutrients from residing within the squid [2]. Distribution of this aquatic relationship is limited by the habitat of the squid (Hawaii). Several bioluminescent bacteria cycle through a single squid daily. Description of Relationship: The type of relationship observed between Euprymna scolope(Hawaiian Bobtail squid) and Vibrio fischeri(bioluminescent bacterium) is unique to organisms with specialized structures called light organs. These light organs are specialized structures that have evolved to allow the organisms that house them to create light. While the evolutionary reason for this structure is unknown, many individuals hypothesize that certain marine organisms form these ...
