Answer the following question given this paragraph: Resistors in an AC Circuit Just as a reminder, consider Figure 23.47, which shows an AC voltage applied to a resistor and a graph of voltage and current versus time. The voltage and current are exactly in phase in a resistor. There is no frequency dependence to the behavior of plain resistance in a circuit:. Q: The voltage and current are exactly in phase in a what? Choices: - battery - capacitor - harmonic - resistor A:
resistor
Answer the following question given this paragraph: Q: If both atoms are the same, they have the same electronegativity and share what type of bond? Choices: - metabolic - ionic - isotopic covalent - nonpolar covalent A:
nonpolar covalent
Q: Answer the following question given this paragraph: Heat from a wood fire can boil a pot of water. If you put an egg in the pot, you can eat a hard boiled egg in 15 minutes (cool it down first!). The energy to cook the egg was stored in the wood. The wood got that energy from the Sun when it was part of a tree. The Sun generated the energy by nuclear fusion. You started the fire with a match. The head of the match stores energy as chemical energy. That energy lights the wood on fire. The fire burns as long as there is energy in the wood. Once the wood has burned up, there is no energy left in it. The fire goes out. Q: How does the sun generate energy? Choices: - atomic division - matter multiplication - certain fusion - nuclear fusion A:
A: nuclear fusion
Question: Answer the following question given this paragraph: Figure 2.9 Two or more atoms may bond with each other to form a molecule. When two hydrogens and an oxygen share electrons via covalent bonds, a water molecule is formed. Q: Two or more what may bond with each other to form a molecule? Choices: - particles - clouds - quarks - atoms A:
Answer: atoms

Answer the following question given this paragraph: Bottleneck effect occurs when a population suddenly gets much smaller. This might happen because of a natural disaster such as a forest fire. By chance, allele frequencies of the survivors may be different from those of the original population. Q: What effect occurs when a population suddenly gets much smaller, due to natural disaster or other cause? Choices: - convergence effect - limitation effect - extinction effect - bottleneck effect A:
**Answer**
bottleneck effect

Answer the following question given this paragraph: The immune system protects the body from worms, germs, and other agents of harm. The immune system is like a medieval castle. The outside of the castle was protected by a moat and high stone walls. Inside the castle, soldiers were ready to fight off any invaders that managed to get through the outer defenses. Like a medieval castle, the immune system has a series of defenses. In fact, it has three lines of defense. Only pathogens that are able to get through all three lines of defense can harm the body. Q: What system protects the body from worms, germs, and other agents of harm? Choices: - digestion - hormones - lymph system - immune A:
(Answer)
immune
