Answer:
The correct answer is (C) A flexible lipid double layer. The cell membrane is often referred to as a "fluid mosaic," a flexible structure

Answer:
The correct answer would be b. Their cells are small and lack a nucleus.
Both archaea and bacteria are prokaryotic organisms that is, they both are devoid of a nucleus and other membrane-bound organelles such as mitochondria, chloroplast et cetera.
They also share a similarity in terms of shape and size of the cells. Both of them are unicellular in nature and can not be seen by naked eyes.
They show variations in their genetic and biochemical ways. For example, archae contains three RNA polymerases whereas bacteria contain a single RNA polymerase.
Their cell wall also show variation in composition. For example, a bacterial cell wall contains peptidoglycans, whereas archae cell wall does not.
Thus, we can say that archae and bacteria are similar in a manner that their cells are small and lack a nucleus.
Answer:
Valinomycin is an antibiotic that are mainly used against the bacteria streptomycin. The valinomycin might also acts as the ionophore used for the regulation of the ions transport.
Only some selected particles can pass down to the plasma membrane. The hydrophobic molecule can easily cross the plasma membrane. Valinomycin is hydrophobic on its exterior surface and easily diffuse through the cell membrane. Valinomycin is hydrophillic from the interior surface and used for the encapsulation of the polar ions.
