A patient who has been diagnosed with cancer has been given a blood test in order for their doctors to investigate their genetic code. What information from the test would help confirm the patient's cancer diagnosis? A) Data indicating somatic cell production is being inhibited by the patient's cancer cells.

B) Data indicating there is a genetic mutation in a protein controlling the patient's cell’s cycle.

C) Data indicating gametes are becoming diploid cells due to the introduction of cancerous cells.

D) Data indicating that cells are increasing their chromosome number due to the occurrence of cancer cells.

Over the past 60 years, many amphibian species have experienced significant population declines and some species have become extinct. scientists suspected that local human activities such as the destruction of wetlands, regional pollution, and deforestation were the main reasons for these losses. however, research over the past 20 years reveals significant amphibian population declines in protected areas of the world, such as nature preserves and parks. these global declines suggest widespread problems including increased ultraviolet radiation, acid rain, and disease. in switzerland, for example, 14 of the 20 native amphibian species are threatened with extinction. chytridiomycosis is a fungal disease first identified in 1998 as a cause of massive amphibian deaths. in some severely impacted populations, a few individuals have survived, perhaps because of some natural resistance. if these resistant individuals continue to survive and prosper, new resistant populations might emerge. this would be an example of the founder effect artificial selection genetic drift natural selection sexual selection
