Which of the following traits of bacterial cells differ signifcantly from the other domains of life?
choose one or more:
a. translation elongation factors
b. dna as genetic material
c. type of rna polymerase
d. peptidoglycan in cell envelope
e. nature of genetic code
f. phospholipids in membrane

Option (A), (B), (D) and (F).

Explanation:

Bacteria are involved in the domains of eubacteria and archaea. Bacteria are different from the other organism and shows different in the chemical and cellular structure of the cell.

The translation elongation factors are different in bacteria and other organisms. The translation factors of bacteria are EF-Tu and EF-Ts whereas the eukaryotic elongation factors are eEF-1 subunit α and eEF-1 subunit βγ. A single RNA pol is present in bacteria and three different RNA pol is present in eukaryotes. Peptidoglycan is present in prokaryotes. Phospholipids contain ester linkage in bacteria and ether linkage in archaea.

Thus, the correct answer is option (A), (B), (D) and (F).

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.
