Answer the following question given this paragraph: (A) A wave consists of alternation crests and troughs. The wavelength () is defined as the distance between any two consecutive identical points on the waveform. The amplitude is the height of the wave. (B) A wave with a short wavelength (top) has a high frequency because more waves pass a given point in a certain amount of time. A wave with a longer wavelength (bottom) has a lower frequency. Q: What is the term for the height of the wave? Choices: - magnitude - frequency - vibration - amplitude A:
amplitude
Answer the following question given this paragraph: Q: Processing of filtrate in the proximal tubule helps maintain what level in body fluid? Choices: - homeostasis - temperature - metabolic level - ph A:
ph
Q: Answer the following question given this paragraph: Beneath the crust is the mantle . The mantle is made of hot, solid rock. Through the process of conduction, heat flows from warmer objects to cooler objects ( Figure below ). The lower mantle is heated directly by conduction from the core. Q: What layer, made of hot, solid rock, is beneath the earth's crust? Choices: - marble - core - magma - mantle A:
A: mantle
Question: Answer the following question given this paragraph: Surface waves travel along the ground outward from an earthquake's epicenter. Surface waves are the slowest of all seismic waves. They travel at 2.5 km (1.5 miles) per second. There are two types of surface waves. Love waves move side-to-side, much like a snake. Rayleigh waves produce a rolling motion as they move up and backwards ( Figure above ). Surface waves cause objects to fall and rise, while they are also swaying back and forth. These motions cause damage to rigid structures during an earthquake. Q: What type of waves are the slowest of all seismic waves? Choices: - core waves - thick waves - central waves - surface waves A:
Answer: surface waves

Answer the following question given this paragraph: If a cell were a house, the plasma membrane would be walls with windows and doors. Moving things in and out of the cell is an important role of the plasma membrane. It controls everything that enters and leaves the cell. There are two basic ways that substances can cross the plasma membrane: passive transport and active transport. Q: In how many basic was can substances cross the plasma membrane? Choices: - one - three - four - two A:
**Answer**
two
