A. thin walls
B. surrounded by blood vessels
C. small numbers of them in each lung
D. large surface area
Do not scam me using links or attachments (except photos of the answer) or answer this by saying a simple yes or no because that also scams me.
Answer:
the answer is a i hope this helps
Explanation:
The sac-like structure of the alveoli increases their surface area. In addition, the alveoli are made of thin-walled parenchymal cells. These features allow gases to easily diffuse across the cells. so the
Alveoli has thin walls which are surrounded by blood vessels, and they have maximized are for gas exchange. Thus, option A, B, and D are correct.
What are Alveoli?These are basic respiratory units, which are balloon like structure present in the lungs, where exchange of gases takes place. A pair of human lungs can contain approximately 480 million alveoli, which produces about, 50 to 75 square meters surface are.
Alveoli are made of thin walls, and they are covered by a rich blood supply through capillaries, this supplies a diffusion gradient for oxygen to move into the blood and carbon dioxide to move into the lungs.
Therefore, the larger surface area, presence of thin wall, which is only one cell thick, and rich blood supply due to presence of blood vessels enable them to exchange gases efficiently.

A.
1
B.
2
C.
3
D.
4
Arrow 4 show convection. Thus option 4 is correct.
What is convection ?
The process in which transfer of heat occurs by movement of a heated fluid either air or water called as convection.
Initially the heat transfer through conduction, however a bulk heat transfer takes place due to the motion of the fluid.
The mechanism of convection involved, fluid is heated from below, leads to thermal expansion.
So that the lower layers, which are hotter now, become less dense.
So the less denser layer replaced by colder layer due to buoyancy nd colder layer is more dense.
This process continuously occur and heat transfer occur through convection
It occurs in both liquid and gases, may be natural or forced, bulk transfer occur.
Thus option 4 is correct.

Answer:
Sorry I really just needed the points ;(
Explanation:
Answer:
1) Amplitude of wave A: 0.5 meters
2) You would have to find the wavelength with the equation λ = [tex]\frac{v}{f}[/tex]
Explanation:
1) Amplitude of a wave is the height of the wave from the horizontal line drawn on "0" to the highest point on the wave.
2) λ is lambda, sign for the wavelength. V is the velocity of the wave, and F is the frequency of the wave.
