Question: Answer the following question given this paragraph:   The photo above represents water in three common states of matter. States of matter are different phases in which any given type of matter can exist. There are actually four well-known states of matter: solid, liquid, gas, and plasma. Plasma isn’t represented in the iceberg photo, but the other three states of matter are. The iceberg itself consists of water in the solid state, and the lake consists of water in the liquid state.   Q: What are the four well-known states of matter?   Choices:  - solid, liquid, gas, and wave  - solid, liquid, plasma, and metal  - solid , imine , gas , and plasma  - solid, liquid, gas, and plasma  A:
Answer: solid, liquid, gas, and plasma

Question: 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:
Answer: eukaryotic

Question: Answer the following question given this paragraph:   In an electrically neutral atom, the number of protons equals the number of electrons.
