Answer:
organic matter ; plant decay
Explanation:
<u>Mud</u>
Mud is a loamy soil that is mixed with clay or silt and water. It is a sticky substance and does not flow. Mud is usually formed after any rainfall a or is formed near the water bodies.
Thus water is the main component for the formation of mud along with soil, plant decays, clay minerals, rock decay, etc. Mud is a sticky substance.
In the context, when I got out of the mud, the mud covered my shoe and it got splattered all over my pants. Thus the sticky mud contains a lot of organic matter that is derived from the plant decays.
Answer:
A field research
Explanation:
Carla noticed that most students got to the college around 8:00 am, and proposed that in order to get a good parking spot, a student would need to get to the college before 7:45 am. She decided to observe for a few weeks to see if she was right. This type of research is <u>a field research</u>.
Field research is a type of research that involves the study, observation, interaction and understanding your test subjects while they are in their natural state or environment. Observational studies, survey research and data collection are examples of field research. Notice that Carla did not notify anyone of the study, he simply observed and the individuals were in their natural state or environment, it was an observational study.
Answer:
The correct answer is: overstate
Explanation:
The substitution bias in economic index numbers appears when the possibility of a consumer to change the consumption of a good - that has become more expensive relative to others - for a cheaper one, is ignored. Thus, looking at the CPI (Consumer Price Index), as an indicator of how much the consumer cost of living has raised over time, without eliminating the substitution bias, can over-estimate this inflation effect.
