I'll give 30 points and make you the brainiest so please answer ASAP 2. How can a model can be used to develop a testable hypothesis?
a. Conceptual models are not based prior observations and are guesses used to generate a hypothesis.

b. Conceptual models are never revised once they are made.

c. Conceptual models help us see how things are related and how they connect or
work together. This helps us develop a hypothesis based on changes in a variable and the
corresponding response of another variable.

d. Conceptual models cannot be used to develop a testable hypothesis.

3. What are the three factors that contribute to water scarcity?
a. Climate change, overuse of groundwater, and water pollution.

b. Hurricanes, overuse of groundwater, and water pollution.

c. El niño, hurricanes, and ocean drought.

d. Climate change, ocean droughts, and water pollution.

Where are the trade winds located?
a. Halfway between the equator and the poles.
b. Near the equator.
c. Above the poles.
d. Near the poles.

What happens when water turns into water vapor?
a. Water turns into water vapor when it loses energy and moves from the gas to the
liquid phase.

b. Water turns into water vapor when the water molecules get enough energy to
move from the liquid phase to the gas phase.

c. What turns into water vapor when it undergoes a chemical reaction and changes
into a new substance.

d. Water cannot become water vapor.

Thomas his older brothers, who own a junk yard, on the weekends to earn extra money. he likes to them push broken-down cars to the back of the junk yard because it makes him feel strong. last saturday, they pushed three cars with different weights, and he noticed he used different amounts of force for each one. the cars were the following weights: white car: 2,700 kg red car: 1,500 kg blue car: 2,100 kg think about how much force is needed to move each car. which correctly lists the cars in order from the most to least amount of force needed to move them? a) white, blue, red b) blue, red, white c) red, white, blue d) white, red, blue

Which of the following statements comparing electron microscopy and light microscopy is false? which of the following statements comparing electron microscopy and light microscopy is false? both the electron microscope and the light microscope use the same wavelengths for illumination. images produced by light microscopes can be in color, whereas electron microscope images are black and white unless they are artificially colored. the electron microscope has greater resolution than the light microscope. electron microscopes can allow examination of viruses and internal cell structures, whereas light microscopes are limited to objects that are 0.5 micrometers and larger. request answer

The inside surface of a cylindrical-shaped cave of inner diameter 1.0 m is continuously covered with a very thin layer of water. the cave is very long and it is open on both ends. the water on the cave surface is at a constant temperature of 15.5 °c. the cave is constantly exposed to wind such that 15.5 °c air flows through the cave at 4.5 m/s. the kinematic viscosity of the air is 14.66 x 10-6 m2/s and the molecular diffusion coefficient of water vapor in the air is 0.239 x 10-4 m2/s. because the cave diameter is so large, the flow of wind down the length of the cave, in the x direction, can be treated like it is external flow and the cave surface can be approximated as flat where appropriate. calculate the x value, in a) the transition to turbulent flow occurs at rex meters, where the air flow transitions from laminar to turbulent along the inside surface of the cave b) calculate the x value, in meters, where the bulk steady state concentration of water vapor in the air flowing in the cave is 10% of the saturation concentration. assume the air at the surface of the water layer is 100% saturated with water vapor. assume the wind entering the cave contained no moisture before it entered the cave. take into account the transition from laminar to turbulent flow when solving part b
