When scientists carefully measure the lichens and agree on their thickness and how often they appear which parts of the scientific cycle are scientists using

This question is incomplete; the complete question including the options are as follows:

During a study of lichens and air quality in part of China, scientists measure the thickness of lichens and estimate how many rocks and trees are covered with lichens in one town. The scientists are following the scientific cycle of observing while using a systematic process, establishing facts, explaining facts, and then returning to the systematic process to collect more facts.

When scientists carefully measure the lichens and agree on their average thickness and how often they appear, which parts of the scientific cycle are the scientists using?

A- process and facts, because they are using a systematic method to measure and then record data

B- process and facts, because they are observing lichens and air quality and describing why they are related

C- explanation and process, because they are using a systematic method to measure and then record data

D- explanation and process, because they are observing lichens and air quality and describing why they are related

The answer is A. process and facts, because they are using a systematic method to measure and then record data

Explanation:

Scientific experiments follow a series of well coordinated steps. These steps range from making observations to analyzing data. In this experiment, which involves scientists conducting a study of lichens and air quality in a part of China, a scientific cycle is being followed.

However, the scientists get to a point where they carefully measure the lichens and agree on their average thickness and how often they appear. This point is where the ANALYSIS OF DATA in the experiment occurs. Therefore, the part of the scientific cycle they are using is PROCESS and FACTS, because they are using a systematic method to measure and then record data.

well, you see. the answer to your question is quite simple. the thing that is big, powerful, and over 9,000 is your mom.
