- Visit the website of the National Center for Health Statistics. Spend some time studying the leading causes of death for different age groups at www.cdc. gov/nchs/data/nvsr/nvsr56/nvsr56_05.pdf. What are the three leading causes of death for each age cohort listed? What are some of the policy implications?To create a survivorship curve for the Andean condor: Graph Title: Survivorship Curve for Andean Condor Y-axis: Labeled "Survivorship" with indicators for "Low," "Medium," and "High" levels, ranging from 0 to 100% of the total initial cohort size. X-axis: Labeled "Life Span" with stages "Young" (0-5 years), "Middle-aged" (6-37 years), and "Old" (38-75 years). Key Features of the Curve: Begins high, reflecting near-total survival from birth to maturity due to low mortality and protected upbringing. remains flat and high through the middle age, indicating sustained low mortality. shows a steep decline in old age, representing increased mortality as individuals reach the latter part of their lifespan.Describe Type I, Type II, and Type III survivorship curves and explain how life tables and survivorship curves indicate mortality and survival.
