Answer:
Testing Platismatia glauca could help scientists understand which pollutants have the largest effect on lichen populations. It also may help scientists understand the current pollutant levels in the atmosphere compared to the population of lichens on the trees. This information can help them more accurately predict population changes over time.
 hope this helps:)

The patient does
not respond adequately to fluid replacement and
was given an IV infusion of dopamine hydrochloride at 5 mcg/kg/minute. In addition, to
monitor that the drug is having the desired effect, the nurse should assess the
client for increased cardiac output. <span>At medium doses, which is between 4 – 8 mcg/kg/min, the dopamine
hydrochloride slightly increases the heart rate and improves contractility to
increase cardiac output and recover tissue perfusion.</span>
