The Complement System The complement system is a nonspecific defense mechanism activated in response to invading organisms. This system gets its name from the fact that it complements the action of antibodies. It is the primary mechanism activated by antibodies to kill foreign cells by forming membrane attack complexes. In addition to directly lysing the invading organisms it also reinforces the general inflammatory tactics. It can be activated in two ways: 1. A nonspecific innate immune

about vector organisms such as ticks and mosquitoes and ways to remove them. Vector Organisms and the Diseases They Carry Vector organisms are parasites that transmit various diseases. Two vector organisms are ticks and mosquitoes. These two vector organisms transmit many well-known diseases. Through most of this essay‚ I will be explaining these two different organisms and the diseases that they carry. First‚ I will be explaining deer ticks. Ticks are small spider-like organisms that attach themselves

Environmental Impacts used to enhance a more common food crop‚ such as corn‚ it might introduce a similar allergen which could have a severe health impact to the consumer. An alteration to a certain plant might make it inedible or harmful to another organism such as an insect that relies on it for food. It can harm organisms that are desirable or can upset the balance of the food Organisms that have been

main types of cell division: (1) mitosis and (2) meiosis. (Balls 34) Most cells are produced by a process called mitosis. In mitosis‚ a cell divides and forms two identical daughter cells. (Prescott 102) Each daughter cell then doubles in size and becomes capable of dividing. Most one-celled plants and animals reproduce by mitosis. (Baserga Biology 56) This is also the way most cells in your body and multi-cellular plants and animals reproduce. Mitosis in animal cells takes place in four orderly stages--

Organism Physiology Paper Dolphins are one of the most familiar and unique marine mammals known to people and occupy all the major oceans and seas of the world. Some species are even known to live in larger river systems. Dolphins belong in the kingdom anamalia; phylum‚ corata; class mammalia; order‚ cetacean; sub-order‚ odonteceti; family‚ delphinidae; genus‚ delphinus; and species‚ delphis. Dolphins are believed to have a long evolutionary past dating back several‚ tens of millions of years

GMO stands for Genetically Modified Organisms. This means they undergo a certain forced process where they are introduced to bacteria and viruses to receive different traits to resist diseases or the tolerance of pesticides. GMO crops have been in the news for a very long time and it’s safe to say there are some pretty heated arguments about the topic. These foods that have been introduced to GMO have been tested with the World Health Organization and humans are safe to consume them. All living

relationship between two organisms where one organism benefits but the other is neutral‚ there is no harm or benefit. An example of commensalism is a flatworm attaching to the horsecrab and eating the crab’s food while the crab is not affected.
