The study of wild species that show resistance to aging and extended longevity in environments that are otherwise conducive to short life spans is called:

Primary cell cultures are undifferentiated cells removed directly from their in vivo location and maintained in an in vitro environment.

Stem cells exist in two forms,embryonic and adult.Embryonic stem cells are:

Organisms that have a fixed number of cells when they reach maturity are referred to as:

Definitions of biological aging that are based on mortality are particularly useful in the science of biodemography.

Which insect has found the greatest use in biogerontology?

The rate-of-living theory of aging suggested that life span is related to metabolic rate.

creation of which two professional societies marked the beginning of organized aging research in the United States?

Superior homeostatic control provides a survival advantage that can lead to greater longevity over evolutionary time.
