Answer:
There are two types of proteins: structural proteins and enzymes. Cell organelles must work together to carry out protein synthesis, utilize proteins within the cell, and transport them out of the cell.
I think the answer must be B, although A is technically somewhat true too. Though the liver can regulate acid secretion, thus helping to balance the pH of blood by increasing or decreasing the acid secretion (can rid the body of excess acid through urine), the question doesn't specify that it balances the pH levels of BLOOD, and equally, multiple factors in the body have a role in balancing bodily pH levels, thus it is not the primary function of the liver. Thus, it must be B. The cells in the liver release an enzyme called renin, which activates angiotensin, which in turn activates the hormone aldostrene, which controls salt retention and elimination of potassium in the kidneys, thus affecting blood pressure and fluid balance.

Answer:
The nucleus represents a major evolutionary transition. As a consequence of separating translation from transcription many new functions arose, which likely contributed to the remarkable success of eukaryotic cells. Here we will consider what has recently emerged on the evolutionary histories of several key aspects of nuclear biology; the nuclear pore complex, the lamina, centrosomes and evidence for prokaryotic origins of relevant players.
