Pyrolobus fumarii, an extreme thermophile, can survive at a temperature as high as 113°c. this microorganism could be categorized as which of the following?
a. eubacteria
b. archaeabacteria
c. cyanobacteria

b. Archaeabacteria

Pyrolobus fumarii is the species of archeabacteria. These organisms are known for their ability to survive in the extreme high temperatures. They are called as hyperthermophiles. They are found in the deep sea vent, and beneath the earth crust. The cells of these organisms are circular. They have lobed shaped cocci cells. These organisms are used in processing of agricultural products, animal feeding and other human consumable products.

answer: ice crystals in air

the water from the water body or another source of water gets evaporated as water vapor as an effect of heat on water. these water vapor rises in the upper layers of the earth atmosphere under high atmospheric pressure. the atmospheric pressure of these water molecules starts to decrease due to the effect of cold air. the invisible water vapor condenses into visible water droplets and ice crystals.these ice crystals and water droplets being less denser than the surrounding air floats on air as clouds.
