Answer:
The organism is a prokaryote from the domain Archaea since it lacks organelles and lives in what can be considered an extreme environment.
Explanation:
The organism is <u>single-celled </u>and<u> lacks a nucleus</u>. Prokaryotic organisms generally lack nuclei and other membrane-bound organelles such as mitochondrion and chloroplast. Hence, both attributes are characteristic of a typical prokaryote although being unicellular is not exclusive only to prokaryotes.
<u>Prokaryotes can be bacteria of Archaea</u>. The organism, in this case, also lives in an area that is humid all year round. Such an area can be considered to be an extreme environment. Living in extreme environments is a characteristic that is peculiar to Archaea only.
Organisms in the Archaea domain are generally prokaryotic, unicellular, and live in extreme habitats such as hydrothermal vents, marshes, hot springs, etc.
Ans.
Lipid bilayer is made up of two layers of phospholipids, which show polar, hydrophilic (polar) phosphate groups on surface of cell membrane and non-polar, hydrophobic (non-polar) tails on inner sides. The hydrophobic nature of cell membrane allows transport of small, hydrophobic molecules more quickly than larger, hydrophilic molecules.
Thus, 'the non-polar, uncharged or small molecules, such as water, oxygen and other gases, will diffuse across the lipid membrane most quickly, while the polar, charged or large molecules, such as ions, proteins, and salts, will diffuse most slowly.'
