Answer the following question given this paragraph: When an earthquake occurs under the ocean, it sends waves through the water as well as the ground. When the energy of the earthquake reaches shore, it forms a huge wave called a tsunami. Q: When the energy of the earthquake reaches shore, it forms a huge wave called? Choices: - a surge - a typhoon - a tidal wave - a tsunami A:
a tsunami

Answer the following question given this paragraph: Inhaling is an active movement that results from the contraction of a muscle called the diaphragm. The diaphragm is large, sheet-like muscle below the lungs (see Figure below ). When the diaphragm contracts, the ribcage expands and the contents of the abdomen move downward. This results in a larger chest volume, which decreases air pressure inside the lungs. With lower air pressure inside than outside the lungs, air rushes into the lungs. When the diaphragm relaxes, the opposite events occur. The volume of the chest cavity decreases, air pressure inside the lungs increases, and air flows out of the lungs, like air rushing out of a balloon. Q: Contraction of what large, sheet-like muscle results in inhalation? Choices: - pelvic floor - uterus - deltoid - diaphragm A:
(Answer)
diaphragm
Ques: Answer the following question given this paragraph: Plants alternate between diploid-cell plants and haploid-cell plants. This is called alternation of generations , because the plant type alternates from generation to generation. In alternation of generations, the plant alternates between a sporophyte that has diploid cells and a gametophyte that has haploid cells. Q: When plant type alternates from generation to generation what is this called? Choices: - turbidity of generation - differentiation of generation - change in generation - alternation of generation A:
Ans: alternation of generation

Answer the following question given this paragraph: 31.2 The Soil Plants obtain mineral nutrients from the soil. Soil is the outer loose layer that covers the surface of Earth. Soil quality depends on the chemical composition of the soil, the topography, the presence of living organisms, the climate, and time. Agricultural practice and history may also modify the characteristics and fertility of soil. Soil consists of four major components: 1) inorganic mineral matter, 2) organic matter, 3) water and air, and 4) living matter. The organic material of soil is made of humus, which improves soil structure and provides water and minerals. Soil inorganic material consists of rock slowly broken down into smaller particles that vary in size, such as sand, silt, and loam. Soil formation results from a combination of biological, physical, and chemical processes. Soil is not homogenous because its formation results in the production of layers called a soil profile. Factors that affect soil formation include: parent material, climate, topography, biological factors, and time. Soils are classified based on their horizons, soil particle size, and proportions. Most soils have four distinct horizons: O, A, B, and C. Q: What consists of four major components: inorganic mineral matter, organic matter, water and air, and living matter? Choices: - nitrogen - color - rocks - soil A:
(A).
soil
Ques:Answer the following question given this paragraph: Power is the rate at which energy is being transferred. Power tells you how many Joules per second of energy is being used to drive something. Thus power is simply the change in energy divided by the time. Since work is by definition the transfer of energy (in or out of a system), power is also equal to the work divided by the time. Efficiency tells you how efficient something is and gives a number between 0 and 1. If the efficiency is equal to 1, then the machine is perfectly efficient (that is all the power used to drive it goes to the out put of the machine with no energy losses). If the efficiency is zero, then all of the input power is lost in the machine and the machine can not output any energy. Q: What is the rate at which energy is being transferred called? Choices: - electric - force - pressure - power A:

Ans:power
Answer the following question given this paragraph: Some elements have been known for centuries (gold, silver, iron, copper, among others) while others have been created in the lab only within the last several years. Most elements do not exist as such in nature. They are so reactive that they can be found only in combination with other materials. Q: What is the term for the process in which water vapor changes to tiny droplets of liquid water? Choices: - dispersion - vaporization - diffusion - condensation A:
condensation
