Clouds are formed when air contains as much water vapor as it can hold. This is called the saturation point, and it can be reached in two ways. First, moisture accumulates until it reaches the maximum amount the volume of air can hold. The other method reduces the temperature of the moisture filled air, which in turn lowers the amount of moisture it can contain. Saturation, therefore, is reached through evaporation and condensation, respectively. When saturation occurs, moisture becomes visible water droplets in the form of fog and clouds.

Two features that Eukaryotic cells have and prokaryotic cells lack:
1) Nucleus
2) Nuclear bound organelles like chloroplasts, Mitochondria, Golgi appratus etc
Hope this helps!
The point at which the toxin would interrupt normal cell signalling in the pathway is the signal amplification.
This is because of the G-protein uncoupling and inhibition of signal amplification by pertusis toxin. Pertusis toxin released by the bacteria Bordetella pertusis and prevents signal that is amplifying from the protein. The G-protein coordinates the interaction between membrane bound receptor proteins and the effector proteins involved in the intracellular signalling. The toxin promotes the uncoupling of this heterotrimetric protein and also inhibits the amplification thus preventing the interaction of the receptor proteins and the second messengers.
Answer:
i am so sory! i cant see the picture
Explanation:
I think
forests maintain the composition of air because of photosynthesis, and the sunlight that lets it put right type of air in position ?
I am sorry, i am new..I tried my best !
