A valid conclusion based on the data collected over this nine-week study is that
stimuli are detected, and actions are taken
a reduction of autotrophs when the number of herbivores is not being kept in check by the wolves
is not involved in other types of reactions because enzymes are specific
technological advances often involve environmental trade-offs
carbon dioxide and water
Td vaccine does not stimulate the immune system of people to recognize pertussis antigens
the size of the duckweed population is kept stable by limited resources in the ditch
Each ecosystem contains different physical conditions that determine the type of living organisms present there.
Td does not protect against pertussis because the
