Marcy uses ph strips to measure the ph of water samples from several ponds in the city park. which reason explains why using a ph meter would improve the accuracy of her data?

Hi!

The correct answer would be that a pH meter can distinguish smaller differences in pH as compared to a pH strip.

A pH meter is a device that measures the hydrogen ion activity in the sample to be tested, and uses the measurement of this activity to determine the degree of acidity or alkalinity of a sample. The hydrogen ions in the sample generate a voltage. The pH meter associates particular voltages with a specific pH value.

A pH strip, on the other hand, is a quick method which uses color changes that are incurred in the pH strip as an indicator of the value of pH. Various colors are specific to specific pH values.

Hope this helps!

step 1: nitrogen fixation- conversion of atmospheric no₂ into forms useful to plants by lightning, bacteria, and cyanobacteria.

step 2: nitrification-process of converting ammonia to nitrite or nitrate.

step 3: assimilation-plant roots absorb new form of nitrogen.

step 4: ammonification-conversion of organic nitrogen to ammonia by bacteria involved in decomposition.

step 5: denitrification-bacteria turns the decomposed matter back into n₂o, which is released into atmosphere; repeat cycle.
