- Explain the loss-of-function mutation ?arrow_forwardDiscuss both the danger of exposure to radiation and the use of radiation as a cancer therapy. With regard to dangers, is all radiation believed to be harmful? Elaborate on the types of radiation and their relative risks, providing explanations at the particulate level to support your claims. For therapeutic radiation, what are some ways that radiation is generated, controlled, and administered? How is this safe, considering the first part of this prompt? Explain any undesired consequences of radiation therapy.arrow_forwardIdentify three different ways that growth can occur in the human body.arrow_forward
- Distinguish between the effects that radiation can have on a general body cells (somatic) and cells which form the gonads/ sex organs (germline or hereditary) when exposed to a significant dose of radiation.arrow_forwardhow are the hallmarks resisting cell death and enabling replicative immortality essential for cancer development. explain each in 3-5 sentences.arrow_forward] Mr. X, aged 85, was recently diagnosed with a particular type of brain tumor and was referred to Dr. Y, chief of surgery at the nearby university hospital, for further evaluation. This type of tumor is benign in 60% of cases and is malignant in the other 40% of cases. Mr. X’s remaining lifetime will depend on the type of tumor (benign or malignant) and on the decision whether or not to remove the tumor. The table below shows the estimates of Mr. X’s remaining lifetime according to the most up-to-date information known about this type of tumor. Tumor Leave tumor Remove tumor Benign 8 5 Malignant 1 5 Dr. Y could perform exploratory surgery before deciding whether or not to remove the tumor to assess the status of the tumor better. Exploratory surgery indicates a benign tumor 75% of the time if the tumor is indeed benign. The surgery is known to indicate a malignant tumor 65% of the time if the tumor is indeed malignant. Exploratory surgery itself is dangerous: there is a 5% chance…arrow_forward

Simple explanation please.arrow_forward14 C fill the blank with correct answerarrow_forwardWhat are two major disadvantages of MRI scans? release of radiation and poor quality images high cost and the need for shielding from the magnetic signals can only view metabolically active tissues and inadequate availability of equipment release of radiation and the need for a patient to be confined to metal tube for up to 30 minutesarrow_forward
- Part I – SymptomsCallie was 26 years old when she opened a bakery called “Callie’s Cupcakes” in downtown San Francisco with herf ancé, Jeremy. Despite the competitive market, her business was booming; everyone loved the clever recipes and thetrendy atmosphere. Between running their fast-growing business and planning for their wedding, Callie hadn’t beenable to keep to her usual eight hours of sleep a night. Although she had always lived a very healthy lifestyle, exercisingdaily and eating healthy, she just hadn’t been feeling herself lately. She was tired all the time, had dif culty breathing,felt stressed, coughed up sputum, consistently ran a low-grade fever, and had lost weight as her appetite decreased.None of these symptoms alone had been particularly alarming so she had put of seeing her physician for a few weeks.Questions1. What are Callie’s symptoms? List all that were mentioned.2. Based on the symptoms presented, what are three possible respiratory infectious diseases Callie…arrow_forward10.52 A food-frequency questionnaire is used to measure dietary intake. The respondent specifies the number of servings of various food items he or she consumed over the previous week. The dietary cholesterol is then quantified for each respondent. The researchers were inter- ested in assessing if there was an association between dietary cholesterol intake and high blood pressure. In a large sample of individuals who had completed the questionnaire, 250 persons with a high dietary cholesterol intake (greater than 300 mg/day) were selected, and 250 persons with a low dietary cholesterol intake (less than 300 mg/day) were selected. The 500 selected participants had their medical histories taken and were classified as having normal or high blood pressure. The data are given here.
