Answer the following question given this paragraph: Amphibians reproduce sexually. Fertilization may take place inside or outside the body. Eggs are laid in water. They hatch into larvae that live in the water until they undergo metamorphosis to the adult form. Q: Where do amphibians lay their eggs? Choices: - in caves - on land - in airborne nests - in water A:
in water

Answer the following question given this paragraph: An inclined plane is a simple machine consisting of a sloping surface that connects lower and higher elevations. The ideal mechanical advantage of an inclined plane is always greater than 1. Q: What do you call a simple machine consisting of a sloping surface that connects lower and higher elevations? Choices: - lever - wedge - jack - inclined plane A:
(Answer)
inclined plane
Ques: Answer the following question given this paragraph: in a one-liter container (Figure 22.15). In this case, the force exerted by the movement of the gas molecules against the walls of the two-liter container is lower than the force exerted by the gas molecules in the one-liter container. Therefore, the pressure is lower in the two-liter container and higher in the one-liter container. At a constant temperature, changing the volume occupied by the gas changes the pressure, as does changing the number of gas molecules. Boyle's law describes the relationship between volume and pressure in a gas at a constant temperature. Boyle discovered that the pressure of a gas is inversely proportional to its volume: If volume increases, pressure decreases. Likewise, if volume decreases, pressure increases. Pressure and volume are inversely related (P = k/V). Therefore, the pressure in the one-liter container (one-half the volume of the two-liter container) would be twice the pressure in the two-liter container. Boyle's law is expressed by the following formula:. Q: Boyle discovered that what property of a gas is inversely proportional to its volume? Choices: - temperature - amount - mass - pressure A:
Ans: pressure
(Q).
Answer the following question given this paragraph: Sometimes people who are feeling anxious breathe too fast and become lightheaded. This is called hyperventilation. Hyperventilation can upset the pH balance of the blood, resulting in blood that is too basic. Explain why. Q: What also happens when people feel anxious and breathe too fast? Choices: - they become pettite - they become hostile - they become elated - they become lightheaded A:
(A).
they become lightheaded
Ques:Answer the following question given this paragraph: Compounds can also react with oxygen, possibly creating oxides of more than one element. When methane burns, carbon dioxide and water are produced. Q: When methane burns, what is produced along with carbon dioxide? Choices: - nitrogen - hydrogen - oxygen - water A:

Ans:water
Answer the following question given this paragraph: Not all changes in matter involve chemical reactions. For example, there are no chemical reactions involved in changes of state. When liquid water freezes or evaporates, it is still water. No bonds are broken and no new products are formed. Q: Changes of state of matter do not involve what type of reaction? Choices: - gaseous reaction - radiation - mechanical reaction - chemical reaction A:
chemical reaction
