What is the charecteristics of an alveolus​
Alla [95]
  • Each alveolus is cup-shaped with very thin walls.
  • It’s surrounded by networks of blood vessels called capillaries that also have thin walls.
  • The oxygen you breathe in diffuses through the alveoli and the capillaries into the blood.
  • The carbon dioxide you breathe out is diffused from the capillaries to the alveoli, up the bronchial tree and out your mouth.
  • The alveoli are just one cell in thickness, which allows the gas exchange of respiration to take place rapidly.

a scientist conducted an expirement to determine the effect of the enviroment on the color of fur of a himalayan rabit
Evgen [1.6K]

The Himalayan rabbit's environment entirely determines the color of its coat.  

<h3>How does the environment affect the coat color on the fur of a Himalayan rabbit? </h3>

The color of newborn Himalayan rabbits is either white or light grey. Beginning at the age of four weeks and ending at six months, coloring the coat is a process. The temperature of the environment affects the color of the coat, which grows darker in colder climates and lighter in warmer ones. The Himalayan rabbit's hair turns black when it is subjected to subfreezing conditions. That area's fur finally turned black. The rabbit's newly grown fur will be black in color if the white fur is removed and the animal is kept at a low temperature. Considering this, it is clear that temperature affects the expression of genes that control this organism's fur color.
