to identify two unknown organisms. PROCEDURE I was given unknown #76. I performed the streak plating method with my unknown organisms. To perform this exercise I needed a TSA plate and labeled the bottom of it with my name‚ group number and organism. I also divided the bottom into three sections. After that‚ I sterilized my inoculating loop using the bunsen burner flame. After letting the loop cool‚ I reached into my unknown test tube with my loop and grabbed the organisms. After that I streaked

Mitosis is a cellular process that replicates chromosomes and produces two identical nuclei in preparation for cell division‚ from the original cell two cells are derived‚ each of which possesses the same genetic material. Mitosis has five phases: interphase‚ prophase‚ metaphase‚ anaphase and telophase. Interphase The DNA duplicates during interphase to prepare for mitosis. Chromosomes are not clearly discerned in the nucleus. Prophase Chromatin in the nucleus begins to condense and becomes visible

The Human Being—A Complex Organism Human beings are complex and special organisms as there is a complex organisation of cells in the human body. The organisation in the human body is summarised as follows: Cells—> Tissues—> Organs—> Systems—> Organism. The same type of cells which carry out a specific function are organised into a tissue. For examples‚ a group of muscle cells form a muscle tissue while a group of nerve cells form a nerve tissue. They are organised to work together to perform

“transferring” into you‚ then you should not be concerned about DNA from GMOs either‚”says Layla Katiraee in her article “10 Studies Proving GMOs Are Harmful”(Katiraee). More and more Americans are becoming worried about the use of Genetically Modified Organisms in their food. The controversy of the use of GMOs in food can be understood through examining how they work‚ their disadvantages‚ and their advantages. Farming has transformed so much over the years. Six thousand years ago‚ farmers had holding

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

The Ethics of Genetically Modified Organisms Genetic engineering has become a seriously debated concern in society over the last three centuries. As scientists become closer to finding a way to accomplish it with new technology and less risks‚ the increasing concerns grow. People all over the world are looking for a way to eliminate disease‚ expand lifetimes‚ and preserve resources. When looking at the genetic engineering of many important factors in society such as religion‚ laws‚ and societal

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. Commensalism *Parasitism is a type of symbiotic relationship between organisms of different species

Relationship between organisms and environment Mai Po Nature Reserve is an internationally significant wetland which is actually a flat shallow estuary‚ at the mouth of Sham Chun River‚Shan Pui River and Tin Shui Wai Nullah. Its 380 hectare area with diverse habitats provides a conservation area for mammals‚ insects‚ amphibians‚ reptiles and over 380 species of birds‚ some of which are highly endangered. During the field trip‚ we visited five different habitats‚ including fishponds‚ mangroves

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
