Some orchid flowers so closely resemble some female insects that the corresponding male insect is fooled into “mating” with the flower and thus moving pollen between flowers. A.) Explain/describe what type of interaction is this B.)How is this interaction likely to have evolved?

Compare and contrast the extracellular matrix of animals and the cell wall of plants. Consider their functions and the types of molecules that make up these structures. What properties of these molecules help to fulfill these functions?

A patient with diabetes has a history of foot ulcer progressing to infection. Specifically, this is recurrent diabetic foot infection (DFI). That is, despite apparent success of the treatment the infection continues to reappear.

The initial diagnosis by the pathology laboratory uses microbiological investigation that has identified Staphylococcus aureus in this infection. Further simple analysis by PCR has revealed the presence of common toxins associated with S. aureus infections in the blood, skin and soft tissue and bone.

Describe a research plan you would undertake to identify:

if the recurrence of infection is due to a new infection or the same bacteria remaining present,

the molecular mechanisms used by this specific S. aureus isolate for its colonization,

the molecular mechanisms for its persistence and recurrent cause of DFI disease.

"Global Climate Change" refers to shifting trends in the long-term weather patterns ("climate") across the globe, and includes phenomena such as global warming. At its root is a steady increase in the atmospheric concentration of several gases called "greenhouse gases", some of which are released through burning fossil fuels such as gasoline, coal, and natural gas. One greenhouse gas is carbon dioxide, an input for photosynthesis and an output of cellular respiration. Your assignment for this Discussion Board to is investigate the following questions:

1.What is a greenhouse gas?
2.When and why is carbon dioxide considered a pollutant?
3.How do scientists know that humans are responsible for the increasing levels of carbon dioxide in the atmosphere that lead to climate change?
4.What are the consequences of increases in the concentrations of carbon dioxide and other greenhouse gases?
5.What are some options suggested to help combat this issue?
In your Individual Post, label your answers #1-5 so it is clear which question you are answering. Be sure to cite and reference your sources in APA format so others can check them out when responding to you.

The bacterial one-hybrid assay holds E. coli cells hostage until our protein of interest can active transcription and translation of enzymes from the HIS3 and URA3 genes. These enzymes are needed to produce Histidine and Uridine, which are both needed for cells to grow and divide. Make an estimate, based on enzyme kinetics and any other information you may need, of how many HIS3 and URA3 enzymes will an E. coli cell need to grow and divide at a normal rate. How many are needed when we add 10 mM 3-amino-1,2,4-triazole (3AT) to the growth medium as a competitive inhibitor of HIS3?

Course Culminating Activity Task 20-01 - Treatable Diseases and Disorders
Select a treatable disease or disorder (human or other mammal) and complete the following tasks to explore and understand the disease.

1. Describe the impact of this disease/disorder on the body systems and how the respiratory system, digestive system and circulatory system work together.
2. For the disease/disorder, create an annotated diagram that identifies a possible treatment and explains the steps needed to apply the treatment. (Look at this example of an annotated diagram for ligation and stripping of a varicose vein.)

3- Create a chart for the disease you have selected that shows the impact on: 1-family 2- employment 3- the individual 4-the economy 5-the media 6- health care system

4- Identify and describe a career that may be associated with the diagnosis or treatment of the disease/disorder. Provide the following information in your description:

• How is the career related to the disease/disorder?
• Where in the medical system is this career required?
• What is the job description for this career?
• What post-secondary education is required to pursue this career?
