Biology 104 Chapter 1 exam solved
100%
Bioaccumulation -Correct Answer-Selective absorbtion and strorage of a great variety of molecules. This
allows the accumulation of vitamins and minerals but at the same time can absorb harmful substances.
Even though certain material are dilute in the environment, they can reach dangerous levels inside cells
and tissues through bioaccumulation.
Biomagnification -Correct Answer-Occurs when the toxic burden of a large number of organisms at a
lower tropic level is accumulated and concentrated by a predator at a higher tropic level, and eventually
accumulating high levels of toxins.
Scientific Meathod -Correct Answer-1) Observe
2) Hypothesis
3) Test and Predict
4) Data
5) Interpret
Scientific Theory -Correct Answer-Supported by an overwhelming body of data and experience, and is
genrally acccpeted by the scientific community.
Probability -Correct Answer-A measure of how likely something occurs.
Experimental design -Correct Answer-Experimental design can reduce bias and blind experiments can
avoid bias in a controlled study.
Natural Experiment -Correct Answer-Involves an observation of events that already happened.
Manipulative experiments -Correct Answer-Conditions are deliberatley altered and all other variables are
held constant. Mostly done in a laboratory.
