Answer the following question given this paragraph: Skepticism is an attitude of doubt about the truthfulness of claims that lack empirical evidence. Scientific skepticism , also referred to as skeptical inquiry, questions claims based on their scientific verifiability rather than simply accepting claims based on faith or anecdotes. Scientific skepticism uses critical thinking to analyze such claims and opposes claims which lack scientific evidence. Q: What is an attitude of doubt about the truthfulness of claims that lack empirical evidence? Choices: - conspiracy - speculation - independent variable - skepticism A:
skepticism
Answer the following question given this paragraph: Imagine scuba diving and coming upon a jellyfish. Would you be startled if the jellyfish suddenly started to glow with bright yellow light, like the jellyfish in the picture above? If so, then the jellyfish would have done its job. Jellyfish give off light to startle possible predators. The light they emit is visible light. Q: What do jellyfish give off to startle possible predators? Choices: - energy - plankton - electricity - light A:
light
Q: Answer the following question given this paragraph: Some solutes, such as sodium acetate, do not recrystallize easily. Suppose an exactly saturated solution of sodium acetate is prepared at 50C. As it cools back to room temperature, no crystals appear in the solution, even though the solubility of sodium acetate is lower at room temperature. A supersaturated solution is a solution that contains more than the maximum amount of solute that is capable of being dissolved at a given temperature. The recrystallization of the excess dissolved solute in a supersaturated solution can be initiated by the addition of a tiny crystal of solute, called a seed crystal. The seed crystal provides a nucleation site on which the excess dissolved crystals can begin to grow. Recrystallization from a supersaturated solution is typically very fast. Q: What is used to recrystallize excess dissolved solute in a supersaturated solution? Choices: - starter crystal - energy crystal - fertilizer crystal - seed crystal A:
A: seed crystal
Question: Answer the following question given this paragraph: The plasma membrane controls what moves inside and outside the cell. Q: What controls what moves inside and outside the cell? Choices: - nucleus - golgi apparatus - mitochondria - the plasma membrane A:
Answer: the plasma membrane

Answer the following question given this paragraph: Frozen precipitation may fall as snow, sleet, or freezing rain. Q: What three forms does frozen precipitation take? Choices: - blizzard, frost, fog - hail, wind, typhoon - vapor, fog, ice - snow, sleet, freezing rain A:
**Answer**
snow, sleet, freezing rain
Q: Answer the following question given this paragraph: Conservation of charge is the fourth of the five conservation laws in physics. There are two charges, positive and negative, and the conservation of electric charge indicates that the total charge in the universe remains the same. In any closed system charge can be transferred from one body to another or can move within the system but the total electric charge remains constant. Q: What are the two types of charges? Choices: - ions and neutrons - energy and mass - volume and acceleration - positive and negative A:
A: positive and negative
