Model organisms are organisms used for research. They are alive‚ non-human species used for the purpose of studying different human diseases or other related experiments in which human testing would be considered either unsafe or unethical. Scientists study a particular biological phenomenon on a model organism and try to relate their findings to other types of organisms that are more difficult to study. As an example‚ 60% of human disease genes have an equivalent in the fruit fly and nematode worm

Phelps‚ Biology 205 MW 2:10pm. Unknown Organism Paper The unknown organism tested in the Mesa lab was collected from in between the toes of my puppy‚ Riley. The original culture grown consisted of dozens of visibly different organisms of varying colony colors and growth patterns. I chose to test a smaller‚ red colony for my experiments. Based on its gram reaction and oxygen requirements‚ the following tests were performed to reach my presumptive ID: Test Performed Result Gram Stain +

A planarian is free-living flatworm that lives in fresh water. Planarians are organisms that live in freshwater. Planarians are part of the metazoan phylum. Animals in the metazoan like jellyfish have the ability to regenerate (Raymond 511-512). Planarians are closely related to animals like jellyfish and starfish. These animals shared the same special ability to regenerate; starfish are able to regenerate their arm when it is cut off. Jellyfish are able to regenerate their stinger when cut off (Li

Organism Physiology The course in which different kinds of living organisms are thought to have developed from earlier forms during the history of the earth is defined as Evolution. Many time organisms evolve due to environmental changes. To better understand evolution this paper will review a diagram of an organism and explain how the organism has evolved physiologically to become suited to fit its environment. Organism To understand the evolution of an organism it is important to understand

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

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

“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

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

Amongst many problems that living organisms face‚ one of the biggest is the change in the temperature of the environment. Why is this a major problem for living organisms? A change in the temperature of the environment disrupts many of the body’s enzymes and regulatory proteins‚ changing their shape and perturbing their function. However‚ organisms have taken two different approaches to tackling this problem we call this organisms endotherms and ectotherms but in this essay‚ we will talk about an
