Tom [10]

In the greenhouse effect, far infrared radiation is emitted from the Earth's surface and absorbed and reemitted by some gases in the atmosphere.

These gases have increased in concentration over the past century.

<h3>What is the greenhouse effect?</h3>

The greenhouse effect refers to the effect that occurs due to certain gases present in the atmosphere which serves as blanket by preventing escape of heat from the earth.

Greenhouse gases include most especially carbon dioxide.

In the greenhouse effect, far infrared radiation is emitted from the Earth's surface and absorbed and reemitted by some gases in the atmosphere.

These gases have increased in concentration over the past century.

Describe the structure of alveolus which is known as tha breating organ.
Dovator [93]
The alveolus (singular form) or alveoli (plural form) are tiny sacs of organs that are attached to the ends of the alveolar duct. These tiny sacs of air are clumped together that form interconnected caves, working together as a unit. They are found inside the lungs and they make the exchange of air easy and possible. Alveoli units are responsible for putting oxygen into the air that we breathe in. Blood that passes through the heart and into the lungs are converted into oxygen which will be then transported by the blood all over the body systems.  
<span>
The walls of the alveoli are extremely thin to enable the quick exchange of gases Aside from this, the linings of alveoli units are fluid in nature enabling gases to dissolve.  </span>

vibrations from the tympanic membrane to the oval window are transmitted by the structures at which numbers?
spin [16.1K]

The 3 and 4 are the structures at which the tympanic membrane to the oval window are communicated.

<h3>An example of a tympanic test</h3>

How well your middle ear is functioning is determined through a test called tympanometry. By tracking the motion of your eardrum, it does this. The outer ear, middle ear, and inner ear are all separate structures that make up your ear. You receive sound as energy or vibrations through your outer ear.

<h3>The tympanic bone's location is unknown.</h3>

The temporal bone's tympanic portion, which surrounds the external portion of the ear canal, is a curving plate of bone that sits under the squamous portion, in front of the mastoid process.
