A researcher studies a mutation that occurs in humans and writes four facts about the mutation in a chart.
1. The mutation is caused as a result of chance.
2. The mutation leads to a genetic disease.
3. The mutation occurs in sperm cells and is passed to the next generation.
4. The mutation is not discovered or fixed by the cell's enzymes.
Based on the information, the researcher concludes that the mutation is harmful. Which statement best supports the researcher's conclusion?

Treatment is often seen as the most important tool for fighting cancer. Do a brief research study on one method of treating cancer in humans. You may discuss 2-3 details about either chemotherapy or radiation therapy, including how it attacks cancer cells and what side effects are experienced by cancer patient receiving this type of treatment.
What might best explain why the incidence of cancer increases as people age?
Select one:
a.
mutations accumulate as people age
b.
cell division increases as people age
c.
protein synthesis increases as people age
d.
telomerase activity increases as people age
e.
ATP production increases as people age

- Describe how different chemicals and radiation can be involved in the development of cancer. Then, describe how chemicals and radiation can be used to treat a patient with cancer.arrow_forwardDavid worked for a decade in a nuclear power plant. After fifteen years he has developed small cell lung cancer. David is anorexic and has lost a much of his original weight. His muscles are wasting, and he is weak. He tries to move around the house throughout the day but tires easily. It has been difficult for him to access care, and he is just starting treatment for his cancer. 1. With continued exposure to the ionizing radiation, DNA damage occurred. What are the three stages of carcinogenesis that occurred after his exposure to radiation? 2. David is a healthy and active man, and his wife often remarked on how much food he used to eat for dinner after work. What would cause the muscle wasting and weight loss now? Explain your answer using what you have learned about the metabolic changes seen with cancer. 3. Muscle weakness may result from the production of onconeural antigens. A. Explain the effects of these antigens? B. In what form would this process likely take in David’s…arrow_forwardRadiotherapy (treatment with ionizing radiation) is one of the most effective current cancer treatments. It works by damaging DNA and other cellular components. In which ways could radiotherapy control or cure cancer, and why does radiotherapy often have significant side effects?arrow_forward
- What separates cancer cells from normal cells? Describe one form of mutation that can increase the risk of a normal cell being cancerous.arrow_forwardScientists are working hard to learn about causes of cancer. It is known that in general terms, cancer-causing agents produce mutations in a variety of genes that control cell reproduction. Cancer can be caused by organisms. For example, when some viruses infect a human cell, the virus DNA inserts itself randomly into the DNA of human cells. Of all the cancer-causing agents to which humans are commonly exposed, tobacco smoke appear to cause the greatest harm. Tobacco is directly responsible for 30% of all cancer deaths in North America. Heavy smoking increases the likelihood of getting lung cancer by 2000%. Passive (second-hand) smoke is less likely to cause cancer. It is about as harmful as all other forms of air pollution. A researcher wants to develop a study to help determine what percentage of smokers will die from cancer caused by tobacco and its smoke. The researcher gathers two groups of subjects and observes them over a long period of time. Identify the manipulated variable…arrow_forwardCancer can arise spontaneously, but it can also be induced as a result of environmental factors such as sun exposure, infections, and tobacco smoking. If you were asked to help allocate resources to cancer research, what emphasis would you place on research to find cancer cures, compared to that placed on education about cancer prevention?arrow_forward
- What human evidence is there that radiation induces cancer?arrow_forwardThe current way to gauge the effectiveness of chemotherapy is to track the size of the tumor. If the tumor shrinks, the chemotherapy is said to be "working." If cancer stem cells really do act the way we think they do, what will be the new way that the effectiveness of chemotherapy will be evaluated?arrow_forwardUltimately, cancer kills because it spreads and disturbs homeostasis. Consider, for example, a kidney cancer that metastasizes to the lungs and liver. What are some specific aspects of homeostasis that the spreading disease could affect?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_forwardChronic liver disease is common among HIV-infected patients, and is increasingly a cause of mortality and morbidity. The disease is usually a result of the destruction and altering of specific liver cell membrane proteins, which damages and kills liver cells. How does HIV influence this activity? A. Protein synthesis is altered in HIV patients due to the insertion of viral RNA. B. Liver disease is a side-effect of several HIV medications. C. HIV halts DNA transcription and inhibits protein synthesis. D. Liver disease is caused by the attack of the HIV virus on the organ itselfarrow_forwardGene therapy (or cell therapy) is the name of a newer type of cancer treatment. Describe an example of how it works, and why it is different from conventional treatments.arrow_forward
