The transcription of a DNA molecule into an mRNA molecule is, and the translation of that mRNA molecule, can occur simultaneously in prokaryotic cells. This does not occur in eukaryotic cells. Which statement explains why transcription and translation can occur simultaneously in prokaryotic cells but not eukaryotic cells.

• Prokaryotic cells have more mitochondria to produce energy.

• Prokaryotic cells lack a nucleus to separate the two processes.

• Eukaryotic cells do not create amino acids until transcription is complete.

• Eukaryotic cells lack ribosomes to translate the mRNA for protein synthesis.

• Nucleus

• Golgi Apparatus

• Cell 1

• Cell 2

• Cell 3

• Cell 4

Rinderpest is a viral disease that infects cattle, wildebeest, and other hoofed animals. The disease had affected cattle and wildlife in the Serengeti region for decades. Death rates were extremely high, especially among wildebeest calves. A program to vaccinate cattle began in the 1950s, and scientists monitored how the program affected wildebeest populations. In 2011, the United Nations declared that vaccination efforts had eradicated rinderpest across the globe. What was the ecosystem's carrying capacity for buffalo, based on the graph, once rinderpest was eliminated?

• 800,000

• 1,250,000

• 1,400,000

• 1,500,000

A protein is built from several polypeptides, each with a different three-dimensional folding pattern. What causes the polypeptides to have different folding patterns?

• The polypeptides are assembled by different ribosomes.

• The polypeptides are assembled in different parts of the cell.

• The polypeptides are composed of different amino acid sequences.

• The polypeptides are controlled by different gene expression processes.
