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:)

Answer:
The correct statements are a, b and d. The incorrect statements are c and e.
Explanation:
Substrate level phosphorylation signifies the generation of ATP from ADP and a phosphorylated intermediate. On the other hand, in oxidative phosphorylation, the formation of ATP takes place from ADP and Pi, that is, an inorganic phosphate.
In substrate-level phosphorylation an enzyme is needed for the reaction to take place. In the process, a dissociation of bond takes place between an organic molecule and a phosphate prior to the formation of ATP. In this, one of the substrates is a molecule obtained from the dissociation of glucose.
In substrate-level phosphorylation, the enzyme taking part in the synthesis of ATP is not required to get attached to the membrane to generate ATP. The phosphate group, which is added to ADP to produce ATP does not come from free inorganic phosphate ions.
Answer:
2 & 4
Explanation:
The theory of spontaneous generation stipulated that life emanated spontaneously from ‘nothing’. This was believed to be true until Francesco Redi & Luis Pasteur later falsified this theory using an experiment. He had two plates of cooked meat. He covered one with a glass bowl and left the other open. The plate with a bowl did not develop maggots while the open one did. This showed that maggot was as a result of hatched eggs that were deposited by flies. Life, therefore, emanates from life.
