NR435 UNH Final Exam Study
questions and answers 2025
acute v. chronic - answer acute=rapid, short course.
chronic=persisting a long time, constantly reoccuring
where is the majority of food wasted? - answer 30-40% lost before it
reaches market due to inefficient harvesting, packaging, or transportation
dose response curve - answer graph that tries to explain the response
versus the dose given of a toxicant. Includes threshold dose, LD(50),
LC(50), and EC(50).
EC(50) - answer concentration of a toxicant that provokes a response,
half way between the baseline and the maximum
LD(50) - answer represents the individual dose required to kill 50 percent
of a population of test animals
LC(50) - answer concentration of dose that will kill 50 percent of the
population
eutrophication - answer water becoming rich in nutrients due to nitrogen
or phosphorous runoffs
hidden/embedded water - answer exchange of water hidden in food and
commodities that require water for their production
overdraft - answer the excessive pumping of an underground basin or
aquafer that exceeds the supply
, negative externalities - answer negative affects that degrade habitats
and way of life. ex. water contamination, pollution
primary threats to Lake Eerie Water Snake - answer 1. Habitat
Destruction
2. Human Persecution
3. Low Population Size
evolution - answer the process by which different organisms have
developed and diversified from earlier forms over time
Leopold's Environmental Worldview - answer World is getting too
populated and too industrialized, everything has economic value. what
about environmental ethics? also we may need to cap population
ECOCENTRIC
functional extinction - answer the population no longer plays a role in the
ecosystem, or isn't viable
local extinction - answer (extirpation) extinct from a specific geological
area
lag time - answer population reaches carrying capacity but doesn't
realize it for a certain amount of time
sustainability + triple bottom line - answer mimic nature in built
environments. meets the triple bottom line- economic, societal, and
environmental
what did Kristen Wyman talk about - answer wampum=jewelry.
sustainability is a choice. Quahog is vital to people's lives, being removed
from contaminated waters. Being a good ancestor=be flexible +
sustainable, think of different ways to look at resources
