Answer the following question given this paragraph: It may be logical to assume that the electrolysis of aqueous sodium chloride, called brine , would yield the same result through the same reactions as the process in molten NaCl. However, the reduction reaction that occurs at the cathode does not produce sodium metal because the water is reduced instead. This is because the reduction potential for water is only -0.83 V compared to -2.71 V for the reduction of sodium ions. This makes the reduction of water preferable because its reduction potential is less negative. Chlorine gas is still produced at the anode, just as in the electrolysis of molten NaCl. Q: Where is chlorine gas produced? Choices: - in the nucleus - carbon cycle - epidermis - at the anode A:
at the anode
Answer the following question given this paragraph: The most common cause of hearing loss is exposure to loud sounds. Loud sounds damage hair cells in the ear that are needed for hearing. Louder sounds damage hair cells more quickly than softer sounds. Q: Exposure to what is the most common cause of hearing loss? Choices: - Guitar - angry sounds - outside sounds - loud sounds A:
loud sounds
Q: Answer the following question given this paragraph: Basic Techniques in Protein Analysis The ultimate goal of proteomics is to identify or compare the proteins expressed from a given genome under specific conditions, study the interactions between the proteins, and use the information to predict cell behavior or develop drug targets. Just as the genome is analyzed using the basic technique of DNA sequencing, proteomics requires techniques for protein analysis. The basic technique for protein analysis, analogous to DNA sequencing, is mass spectrometry. Mass spectrometry is used to identify and determine the characteristics of a molecule. Advances in spectrometry have allowed researchers to analyze very small samples of protein. X-ray crystallography, for example, enables scientists to determine the three-dimensional structure of a protein crystal at atomic resolution. Another protein imaging technique, nuclear magnetic resonance (NMR), uses the magnetic properties of atoms to determine the three-dimensional structure of proteins in aqueous solution. Protein microarrays have also been used to study interactions between proteins. Large-scale adaptations of the basic two-hybrid screen (Figure 17.17) have provided the basis for protein microarrays. Computer software is used to analyze the vast amount of data generated for proteomic analysis. Genomic- and proteomic-scale analyses are part of systems biology. Systems biology is the study of whole biological systems (genomes and proteomes) based on interactions within the system. The European Bioinformatics Institute and the Human Proteome Organization (HUPO) are developing and establishing effective tools to sort through the enormous pile of systems biology data. Because proteins are the direct products of genes and reflect activity at the genomic level, it is natural to use proteomes to compare the protein profiles of different cells to identify proteins and genes involved in disease processes. Most pharmaceutical drug trials target proteins. Information obtained from proteomics is being used to identify novel drugs... Q: The goal of proteomics is to identify or compare what substances expressed from a given genome under specific conditions, study the interactions between them, and use the information to predict cell behavior or develop drug targets? Choices: - cells - dna - rna - proteins A:
A: proteins
Question: Answer the following question given this paragraph: Gas exchange is the movement of oxygen into the blood and carbon dioxide out of the blood. Q: In gas exchange, oxygen flows into the blood, and what flows out? Choices: - naturally dioxide - carbon monoxide - liquid dioxide - carbon dioxide A:
Answer: carbon dioxide

Answer the following question given this paragraph: The sense of taste is controlled by sensory neurons on the tongue. They are grouped in bundles called taste buds. You can see taste buds on the tongue in Figure below . Taste neurons sense chemicals in food. They can detect five different tastes: sweet, salty, sour, bitter, and umami, which is a meaty taste. When taste neurons sense chemicals, they send messages to the brain about them. The brain then decides what you are tasting. Q: Where are the taste buds located in humans? Choices: - lips - mouth - teeth - tongue A:
**Answer**
tongue

Answer the following question given this paragraph: We see many objects out in space that emit light. This matter is contained in stars, and the stars are contained in galaxies. Scientists think that stars and galaxies make up only a small part of the matter in the universe. The rest of the matter is called dark matter . Q: Scientists think that stars and galaxies make up only a small part of the matter in the universe. what is the rest of the matter called? Choices: - typical matter - light matter - cold matter - dark matter A:
**Answer**
dark matter
