Ques: Answer the following question given this paragraph: All that magma and gas pushing upwards can make the volcano's slope begin to swell. Ground swelling may change the shape of a volcano or cause rock falls and landslides. Most of the time, the ground tilting is not visible. Scientists detect it by using tiltmeters, which are instruments that measure the angle of the slope of a volcano. Q: Which instruments are used to measure the angle of the slope of a volcano? Choices: - altimeter - compass - calipers - tiltmeters A:
Ans: tiltmeters

Ans: sunlight

Ques: Answer the following question given this paragraph: 30.5 Transport of Water and Solutes in Plants Water potential () is a measure of the difference in potential energy between a water sample and pure water. The water potential in plant solutions is influenced by solute concentration, pressure, gravity, and matric potential. Water potential and transpiration influence how water is transported through the xylem in plants. These processes are regulated by stomatal opening and closing. Photosynthates (mainly sucrose) move from sources to sinks through the plant's phloem. Sucrose is actively loaded into the sieve-tube elements of the phloem. The increased solute concentration causes water to move by osmosis from the xylem into the phloem. The positive pressure that is produced pushes water and solutes down the pressure gradient. The sucrose is unloaded into the sink, and the water returns to the xylem vessels. Q: Transport of water and solutes in plants water potential is a measure of the difference in potential energy between a water sample and this? Choices: - green water - dirty water - salty water - pure water A:
Ans: pure water

Ques: Answer the following question given this paragraph: Two horrific contraptions on frictionless wheels are compressing a spring by compared to its uncompressed (equilibrium) length. Each of the vehicles is stationary and they are connected by a string. The string is cut! Find the speeds of the vehicles once they lose contact with the spring. Q: Transport of nutrients and regulation of body temperature through fluid flow are characteristics of which bodily system? Choices: - peripheral - gastrointestinal - reproductive - cardiovascular A:
Ans:
cardiovascular
