Biology 155 Final Exam Questions And
Answers 100% Pass
Genetic Theory of Aging - ANS programmed by our genes to age
Hayflick Phenomena - ANS normal cells have a preprogrammed number of divisions
Telomere Theory - ANS ends of chromosomes, the telomeres, shorten w/each division; when
telomere is gone, cell division stops
Gene Mutation Theory - ANS as we age, number of mutations in the body builds up until
there are consequences such as cancer
Cross Linkage Theory - ANS as we age, key proteins cross link to create collagen that can
interfere with biochemical pathways
Free Radical Theory - ANS chemicals produces cause tissue oxidation, reacts with
unsaturated fats in cell membrane, highly damaging
Cellular Garbage Theory - ANS potentially harmful substances build up in the body as we age,
interfere with normal cell and body functions
Energy Bank Theory - ANS living beings have a certain amount of energy to use and its used
up its gone

Wear and Tear Theory - ANS aging is the accumulation of injuries and damage done to the
body
Immune System Theory - ANS aging is caused by a decline in the immune system, eventually
immune system can fail to recognize cancer cells, immune system can attack the body creating
autoimmune diseases
Endocrine Theory - ANS aging is caused by imbalances of the endocrine system; hormone
secretion declines= aging
Average Total Life Expectancy in US - ANS 79.6 years
Average Male Life Expectancy in US - ANS 77.1 years
Average Female Life Expectancy in US - ANS 81.9 years
Small country with longest life expectancy - ANS Monaco: 89.6 years
Large Country with longest life expectancy - ANS Japan: 84.5 years
percent of US population is over 65 y/o - ANS 13%
more men die at a younger age than women because... - ANS men lead riskier lifestyles
more women die at and older age than men because... - ANS more men have already died
