- Which is true for cancer cells: 1) Cell death occurs after a determined number of cell divisions 2) Contact with other cells reduces chance of cell division 3) Cell division occurs in the presence of stop signals.arrow_forwardWhat are Kupffer cells?arrow_forwardThe two samples taken from the patient's 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 reasons, with specific details, why you believe that sample is cancerous. Your answer should be based on the information you calculated in this activity and from our material described in our lectures and notes. I have uplode sample A for question 5 and that I marked the question and sample A and the other picture is sample B for question 9. All informations are included in my question.arrow_forward
