Answer:
middle ear- hammer, anvil, stirrup
cochlea- cavern-like bone with tiny hairs and fluid
eardrum- membrane
outer ear- gathers sound
amplify- make greater
The correct match is gathers sound - outer ear, hammer, anvil, stirrup - middle ear, cavern-like bone with tiny hairs and fluid - cochlea, membrane - eardrum, and make greater - amplify.
The outer ear is the visible part of the ear and includes the pinna (the external ear flap) and the ear canal. Its primary function is to gather sound waves from the environment and direct them into the ear canal. The middle ear is a small, air-filled chamber located between the outer ear and the inner ear. It contains three tiny bones known as the ossicles: the malleus (hammer), the incus (anvil), and the stapes (stirrup). The cochlea is a spiral-shaped, snail-shell-like structure located in the inner ear. It is filled with fluid and contains thousands of tiny hair cells along its walls. The eardrum, also known as the tympanic membrane, is a thin, semitransparent membrane located at the end of the ear canal in the outer ear. Amplify means to increase the magnitude or strength of something. In the context of hearing, the middle ear's ossicles (hammer, anvil, and stirrup) play a crucial role in amplifying the sound vibrations that reach the eardrum.

What roles do society, politics, and economics play in science?
Discovering the roles and influence that society, politics, and economics have on science takes some practice. Sometimes these influences are not obvious but appear only after a solution to the problem has been tested over a period of time.
These articles describe conservation problems and solutions that were influenced by scientific, social, economic, or political issues. As you read each article, take note of the sections that represent these factors. You will use these articles in your assignment for this lesson.

2A) If people stop cutting down as many trees, there won’t be as many resources from that such as paper may be the cost will go up. Companies will be mad if people stop them from doing business, cutting down trees, and making money for example some experiences people had when they confronted companies went like this, "We had chief executives slamming the phone down on us. I even had people threaten to punch me." But there are a lot of good things happening such as a lot of materials are made that are FSC certified so you can have a clear conscience.
3A) If people are cutting down trees, then those companies aren’t getting money then they lose job opportunities without people there doing their jobs then no products like paper can be made. Also, if trees aren’t being cut down clearing space places like houses or malls can’t be built there. There are some solutions though like what FSC certified places do is after they cut down a tree they plant a new one in that exact spot.
4A) A lot of countries are becoming FSC certified such as Russia. Just a little bit ago Russia had a very little forest that was FSC certified now it's 260,000 sq. km—a quarter of its commercial forests. 40 percent—of the forest area of Europe and North America is certified by the FSC...

A forecast indicates a dew point temperature equal to the air temperature. What does this information imply?
A. Relative humidity is 0%, and there is no chance of rain.
B. Relative humidity is 100%, and it may rain.
C. Relative humidity is 0%, and it may rain.
D. Relative humidity is 100%, and there is no chance of rain.
Answer:
B
Explanation:
I hope this helps :) :)
As the dew point temperature equal to the air temperature this implies that the relative humidity is 100%, and it may rain. The correct option is B.
What is relative humidity?Relative humidity (RH) is a percentage ratio of the amount of atmospheric moisture present to the amount that would be present if the air was saturated.
If the air is completely saturated at a specific level, the dewpoint temperature is the same as the actual air temperature, and the relative humidity is 100%.
There would be no clouds, precipitation, or fog if humidity did not exist. Humidity is simply the amount of water vapor in the air that is required to form rain. Furthermore, water vapor retains heat in the air.
Since the dew point temperature is equal to the air temperature, it may rain and the relative humidity is 100%.
Thus, the correct option is B.
