Answer:
a. pass readily through a membrane's lipid bilayer
Explanation:
Molecules or substances move to and fro the cell via the cell membrane, which is selectively permeable i.e. controls the passage of molecules in and out the cell.
Small, non-polar hydrophobic molecules such as fatty acids will not be repelled by lipid-containing cell membrane, hence, enters the cell via SIMPLE DIFFUSION. This means that they pass readily through a membrane's lipid bilayer without aid. Fatty acids are able to do this because they are a class of lipids and are soluble in lipid layer of the cell membrane.

Answer:
The correct answer is d. eukaryotes almost always produce polycistronic mRNA
Explanation:
mRNA can be polycistronic or monocistronic. A monocistronic mRNA contains the information of one gene only so a monocistronic mRNA code only one protein at a time but a polycistronic mRNA can code for multiple proteins at a time.
In eukaryotes, one transcriptional unit carries the information of only one protein so eukaryotes produce monocistronic mRNA but some eukaryotes are capable of having polycistronic mRNA.
In prokaryotes, many genes are transcribed as a unit to produce multiple proteins so prokaryotes produce polycistronic mRNA. Therefore the statement which is not true is d. eukaryotes almost always produce polycistronic mRNA.
