tissues and viewed under the microscope, Sample A from Question 5 and Sample B from Question 9, were part of a diagnostic strategy to identify whether the issue was becoming cancerous. One sample was taken from the suspected cancerous tissue while the other sample was taken from the presumed nearby non-cancerous tissue.   Based on your understanding, which of the two samples likely came from the suspected cancerous site on the tissue?  Provide two well-explained

Dear Expert,  Not quite sure how much of these processes are done by bots but sorry for resubmitting the question, the explanation didn't come through all together. My question is: When you are doing mitosis in a petri dish with plant cells, why are: hormones added, sterile conditions needed and why the temperature must be kept at 20 degrees.  Many thanks

true or false Primary cells are isolated directly from tissues and have not been modified ex vivo using an immortalization protocol.

Hello, i understand the question, but i only need to know which option is right, no need for explanation. thanks in advance.

Why is Alzhemier's disease the 6th leading cause of death in the United States right now?

Keratinocytes are the predominant cell type found in the epidermal layer. Knowing that manyof these cells die each day while an equal number are produced, you are interested inunderstanding where they come from and how the population is maintained.a) You collect a sample of keratinocytes and allow them to grow in cell culture. Thoughthe cells are visibly indistinguishable from each other, you find that some fail to dividewhile others have formed large colonies. What might be different about the two typesof cells?b) You take all the cells from one of the large colonies and grow them on a fresh plate.You see some of the cells again form large colonies, but most fail to divide. Explainthese results.

1) If direct stains work so well, why would we ever use indirect stains? Give two reasons why you might choose to use indirect stains instead of direct stains?  2) Assume that two days (dye A and dye B) were applied to bacterial smear. The cells were stained by dye A while the slide background was stained with dye B. Which stain had an anionic chromogen? Which stain had a cationic chromogen?

The patients described in the table below just checked in to the Alex Py Memorial Hospital & Regional Medical Center. Which are headed to the Department of Nuclear Medicine for a radioimaging procedure? Which are headed to the same place for a radiotherapy procedure? patient Ravi is being treated for early-stage prostate cancer. After surgery to remove the tumor, his oncologist recommended 40 Gy of external X-ray radiation, split into 22 doses, to kill any remaining cancer cells. He is here for his 22nd and final treatment. Karen is taking part in a research study aimed at determining whether X-ray irradiation can ease the symptoms of advanced arthritis. Today she is scheduled to receive the first of ten 1 Gy doses of X-rays to her hip and shoulder joints. 12-year-old Isabel is being treated for acute lymphoblastic leukemia (a type of blood cancer), and her oncologist has recommended a round of CAR T-cell therapy, in which immune cells from her body are removed, re-engineered in the…

There is a report of a new disease affecting approximately 30% of the persons living in a small rural area of Ontario. Affected individuals have a lack of energy and demonstrate a progressive loss of muscle function. Although we have no information yet, we believe the disease is caused by an infectious agent. Consequently, to limit the spread of this disease, immediate intervention is critical. Blood and muscle tissue samples from unaffected and affected individuals are waiting for you. Microscopy and X-ray crystallography facilities are being readied for your arrival. In order to gain information as quickly as possible, please develop a solid research plan before beginning your investigations.   Some possible questions about this new disease could be: Is there evidence of disease at the cellular level? Is the disease caused by an infectious agent? What is the infectious agent? Does the infectious agent attack muscle tissue? How might the infectious agent cause the disease? Is there a…

1) What is embedding?  2) What is the most common embedding medium for formalin-fixed tissues?  3) What is H& E staining and what does it stain?
