En las arqueas, generalmente se encuentra en la forma L-isomérica, mientras que las bacterias y eucariotas tienen la forma D-isomérica. Una segunda diferencia es la presencia de un enlace éter en oposición a los lípidos enlazados a éster que se encuentran en eubacterias y eucariotas.
Correct answer is B!
--------------------------------
If you see meaning of "Unconditioned stimulus", you will see the right answer, firstly what does "Unconditioned Stimulus" means, it means any stimulus that naturally evokes a specific response; see also conditioning. If I would go with choices I would choose correct answer B.

Answer:
The correct answer is "Histones in general have a net negative charge that allow them to bind to DNA. Acetylation of histones, decreases their positive charge and weakens the histone-DNA interaction".
Explanation:
Histone acetyltransferases (HATs) are regulators of gene activation and deactivation, achieved by the transference of an acetyl group from acetyl-CoA to histones. HATs function by the premise that histones in general have a net negative charge that allow them to bind to DNA. Acetylation of histones, decreases their positive charge and weakens the histone-DNA interaction. Therefore, most of the times histone acetylation increases gene expression, because the acetylated gene is free from the histones and is able to be encoded.

Answer:
A species' population that is genetically diverse is more likely to adapt and recover from environmental changes. A genetically diverse population is more likely to possess variations of alleles that are suited for the environment and its changes. Those individuals are more likely to survive to produce offspring bearing that allele.
