Answer the following question given this paragraph: that extends the 3' end, so a primer is synthesized and extended. Thus, the ends are protected. 16 The cell controls which protein is expressed, and to what level that protein is expressed, in the cell. Prokaryotic cells alter the transcription rate to turn genes on or off. This method will increase or decrease protein levels in response to what is needed by the cell. Eukaryotic cells change the accessibility (epigenetic), transcription, or translation of a gene. This will alter the amount of RNA, and the lifespan of the RNA, to alter the amount of protein that exists. Eukaryotic cells also change the protein's translation to increase or decrease its overall levels. Eukaryotic organisms are much more complex and can manipulate protein levels by changing many stages in the process. Q: Which cells change the accessibility, transcription, or translation of a gene? Choices: - endogenous - prokaryotic - ribosomes - eukaryotic A:
eukaryotic

Answer the following question given this paragraph: The last property above requires some additional explanation. We are all familiar with the process of dissolution on a large scale. If you stir a spoonful of salt into a glass of water, the salt crystals are broken down and seem to disappear into the water. On the atomic level, the dissolution of an ionic compound occurs when water interacts with the ions in the crystal lattice, causing the lattice to break apart ( Figure below ):. Q: On the atomic level, the dissolution of an ionic compound occurs when water interacts with the what in the crystal lattice? Choices: - atoms - fractals - particles - ions A:
**Answer**
ions
