Akira records the speed of a reaction, first without a catalyst, and then with a catalyst.

The provided question is incomplete, however the complete question is as follows:

Match the scenarios and scientific practice:

a. Akira records the speed of a reaction, first without a catalyst, and then with a catalyst.

b. Akira creates a reaction without a catalyst, then repeats the reaction with a catalyst.

c. Akira turns in a written lab report to his science teacher.

d. Akira wonders, "Will adding a catalyst speed up this chemical reaction?"

e. Akira writes in his notes that adding a catalyst sped up the chemical reaction because the catalyst lowered the activation energy needed to start the reaction.

1. asking a question

2. performing an investigation

3. collecting data

4. providing explanations

5. communicating results

The correct match is :

collecting data  - a

performing an investigation  -b

communicating results  - c

asking a question  - d

providing explanation - e

Explanation:

Any research have a scientific method to investigate about the research which have to follow a certain steps in order to test the research and these steps include following steps:

1. asking a question: for any research there would be query or question about any natural phenomenon or process how or why its works in a certain way.

2. performing a experiment : an experiment is a scientific method to test a hypothesis that helps in collecting data to support or against the research.

3. In the end or during of experiment there would be data that need to be collected to get to the result of experiment.

4. providing or forming conclusion on the basis of result and data collected.

5. communicating result would be help in understand the result and review.

c. movement because i took the test and it lets me review my answers

events in order:

1.       vishnu schist

2. zoroaster granite

3. bass limestone

4. hakatar   shale

5. igneous intrusion

6. shinumo quartzite

7. dox sandstone

8. tapeats limestone

9. bright angel shale

10. muav limestone

11. temple butte limestone

12. redwall limestone  

nonconformity

answer: the unkar group shows angular unconformity because the layers are turned at angle.

unconformity

answer: specifically the angular unconformity occurs between the cambrian and precambrian rocks. the dox sandstone, shinumo quartzite, hakatar shale, and bass limestone have been filled. an angular unconformity occurs between the cambrian and precambrian rocks. the dox sandstone, shinumo quartzite, hakatar shale, and bass limestone have been filled.

disconformity

answer: the disconformities aremarked irregular lines between the sedimentaryrocks layers.
