Q: Energy that is stored in a person or object is called? Read this paragraph and choose the correct option from the provided answers: Potential energy is energy that is stored in a person or object. Choices: - vertical energy - mechanical energy - kinetic energy - potential energy A:
potential energy

Q: Nervous tissue consists of just two basic types of nerve cells: neurons and? Read this paragraph and choose the correct option from the provided answers: Although the nervous system is very complex, nervous tissue consists of just two basic types of nerve cells: neurons and glial cells. Neurons are the structural and functional units of the nervous system. They transmit electrical signals, called nerve impulses. Glial cells provide support for neurons. For example, they provide neurons with nutrients and other materials. Choices: - white blood cells - red blood cells - mammalian cells - glial cells A:
glial cells

Q: Q: Normal body temperature is ideal for most of what type of reactions? Read this paragraph and choose the correct option from the provided answers: Biochemical reactions are optimal at physiological temperatures. For example, most biochemical reactions work best at the normal body temperature of 98.6F. Many enzymes lose function at lower and higher temperatures. At higher temperatures, an enzyme's shape deteriorates. Only when the temperature comes back to normal does the enzyme regain its shape and normal activity. Choices: - gas - plasma - theoretical - biochemical A:
A: biochemical

Question: Q: When are peptide bonds between amino acids formed? Read this paragraph and choose the correct option from the provided answers: Amino acids can bond together through peptide bonds to form short chains called peptides or longer chains called polypeptides ( Figure below ). A peptide bond is a covalent bond formed from a condensation reaction between two molecules, causing the release of a molecule of water. This bond usually forms between two amino acids, hence forming a peptide or polypeptide. Peptide bonds between amino acids are formed during the process of translation. Choices: - process of transcription - process of migration - process of production - process of translation A:
Answer: process of translation

Q: What happens to the electrical conductivity of metals when placed in a pot of boiling water? Read this paragraph and choose the correct option from the provided answers: levels. If a solid has a filled valence band with a relatively low-lying empty band above it (a conduction band), then electrons can be excited by thermal energy from the filled band into the vacant band where they can then migrate through the crystal, resulting in electrical conductivity. Electrical insulators are poor conductors because their valence bands are full. Semiconductors have electrical conductivities intermediate between those of insulators and metals. The electrical conductivity of semiconductors increases rapidly with increasing temperature, whereas the electrical conductivity of metals decreases slowly with increasing temperature. The properties of semiconductors can be modified by doping, or introducing impurities. Adding an element with more valence electrons than the atoms of the host populates the conduction band, resulting in an n-type semiconductor with increased electrical conductivity. Adding an element with fewer valence electrons than the atoms of the host generates holes in the valence band, resulting in a p-type semiconductor that also exhibits increased electrical conductivity. Choices: - stays the same - increases slowly - increases quickly - decreases slowly A:
**Answer**
decreases slowly

Q: Q: Phosphorus exists as several allotropes, the most common being red, black, and what? Read this paragraph and choose the correct option from the provided answers: Phosphorus exists as several allotropes, the most common being red, black, and white phosphorus. White phosphorus consists of tetrahedral P4 molecules and melts at 44.15C; it is converted to red phosphorus by heating at 400C for several hours. The chemical differences between red and white phosphorus are considerable: white phosphorus burns in air, whereas red phosphorus is stable; white phosphorus is soluble in organic compounds, whereas red phosphorus is not; white phosphorus melts at 44.15C, whereas red phosphorus melts at 597C. If the enthalpy of fusion of white phosphorus is 0.659 kJ/mol, what is its S? Black phosphorus is even less reactive than red. Based on this information, which allotrope would you predict to have the highest entropy? the lowest? Why?. Choices: - purple phosphorus - yellow phosphorous - green phosphorus - white phosphorus A:
A: white phosphorus
