Describe the hearing process​

Answers

Answer 1

So to put this in a question, I would rephrase it to:

How does hearing work?

It's a little tough to ELI5 without using using the names of the particular organs but here goes:

Sound is nothing more than a wave of air pressure. In other words, it fundamentally involves changing degrees of energy-based air pushing and tugging. Additionally, it is because to this that sound cannot travel in a vacuum. When these waves reach your ear, they first come into contact with the "tympanic membrane," which vibrates and transmits these vibrations to the malleus, incus, and stapes, three small bones (Latin for hammer, anvil, and stirrup).

The waves will subsequently be transmitted via the bones' vibrations to the "cochlea," a spiral-shaped organ filled with fluid. The air pressure wave has so undergone many transformations at this point. Air pressure was followed by mechanical vibrations and is now "fluid pressure." The spiral-shaped cochlea is lined with neurons all the way around. Depending on the fluid pressure waves' intensity, frequency, etc., the cochlea will have to travel a particular distance. Based on these fluid waves, these neurons will then activate, sending information to your brain.

Your brain then decodes these messages to produce the "sound" that you hear. Although I'm not convinced this is the greatest ELI5, this is the main idea.

In essence, your ear works as follows:

Air pressure waves enter the ear, transform into mechanical vibrations, transform into fluid pressure waves, which signal neurons and cause those neurons to fire electrical impulses that communicate with the brain the sound you are hearing.

Answer 2

Answer:

Sound waves enter the outer ear and travel through a narrow passageway called the ear canal, which leads to the eardrum. The eardrum vibrates from the incoming sound waves and sends these vibrations to three tiny bones in the middle ear. These bones are called the malleus, incus, and stapes.

Describe an example of a sustainable yield model, other than a forest, that could help you make decisions about how to use your island resources.

Answers

Sustainability is the idea that people may live on Earth and utilise resources without destroying them or affecting future generations. The biological variety, food production, average global surface temperatures, CO2 concentrations, human population, and resource depletion are the five main environmental indicators that might point people in the direction of sustainability.

How can we figure out what yield is sustainable?

The foundation for determining sustainable yield is the ratio of the water level decline in the well to the pumping rate, the amount of drawdown the well exhibits for a particular pumping rate over time, and the recovery rate. Data from aquifer tests are typically more trustworthy the longer they are conducted.

Example is a fish that can be kept alive forever because they can be nourished by the underlying natural system's regenerating abilities.

Answers

What evidence from the experiment shows that conduction occurred? In your answer, be sure to include the materials involved in the transfer of heat through conduction.

Sample Response: The melting of the chocolate pieces one by one showed that it was caused by heat flowing through the foil bridge. The transfer of heat happened between the foil bridge and the chocolate pieces because they were touching each other.

The conduction was made by the foil which was touching the chocolate made the chocolate slowly melt because of the tea light giving heat to the foil the foil conducted it to the chocolate causing it to melt. Thus, option "C" is correct.

What are conduction, convection and radiation?

Conduction refers to the transfer of the energy from one end to the other end from the conducting material. Heat energy, and electric energy all of these can conduct. For example - heat transfer from one end of the road to another.

Convection refers to the process in which heat energy is transferred to the liquid in various manners. For example - a geyser transfers the heat energy to the water.

Radiation refers to the transfer of heat in the form of a heatwave. For example - transferring of heat from the light bulb and heater.

Therefore, the given example can help us to understand the distribution of energy on earth.

Thus, option "C" is correct.
