Answer:
The hearing is ability to perceive sound by detecting vibrations. The auditory ability is sense of sound by the pressure of surrounding medium.
Explanation:
The students are complaining about their sense of sound perception. The inability to perceive sounds is a sort of deafness. The students may have hard time hearing the sound and differences in the tone. This means that their brain is not hearing the sound normally. People can have problem with perception of sound at any age but usually it starts as a child.

The normative economic analysis refers to the model in which a mechanism is studied looking for its possible results, depending on the variables around it. This analysis not only involves the technical evaluation of the situation or mechanism, but also includes the personal appreciation in a way in which ideal situations and ethics are present too.
Answer:
D texture of the jumping surface
Explanation:
An experiment can be defined as an investigation which typically involves the process of manipulating an independent variable (the cause) in order to be able to determine or measure the dependent variable (the effect).
This ultimately implies that, an experiment can be used by scientists to show or demonstrate how a condition causes or gives rise to another i.e cause and effect, influence, behavior, etc in a sample.
A control experiment can be defined as an experiment in which a condition assumed to be a probable cause of the effect is being compared to the same situation by the scientist without involving or using the suspected condition.
In an experiment , the variable being manipulated by an experimenter is known as an independent variable while the dependent variable is the event expected to change when the independent variable is manipulated.
Furthermore, a controlled variable refers to anything or quantity such as group, person, event, etc., that is held constant by the researcher during an experiment and as such is limited.
In this scenario, you are designing an experiment to find out which type of frog can jump farther. Thus, the controlled variable (variable that does not change) in this experiment is the texture of the jumping surface because it is where all the frogs would be tested on i.e used for the jumping test.
The early human civilization were generally settled at a distance from oceans, as they felt that such water is of no use to them.
<h3>What is the significance of early civilizations?</h3>
One of the earliest civilizations in the world began near the rivers and valleys, because they had diversity of natural resources. Moreover, rivers and valleys have been given to birth to agricultural practices.
After knowing about these advantages, people realized that settlements shall never be practiced near the oceans, as the ocean water is not useful for human consumption.
Therefore, the significance of early civilizations has been aforementioned.
