Scientific Method Review read the following scenario and answer the questions:
Students studying respiration decide to test the effect of temperature on the respiration rate of crickets. They
want to know if increasing the respiration rate. Students know that during respiration, organisms obtain oxygen
and release carbon dioxide, so they use carbon dioxide sensors to measure the amount carbon dioxide
produced by crickets exposed to different temperatures.
In Group A, students keep 10 crickets at 19 degrees C (room temperature) for 30 minutes. After 30 minutes,
they use the carbon dioxide sensor to measure to the amount of carbon dioxide produced by the crickets over
a period of five minutes.
In group B, students keep 10 crickets at 47 degrees for 30 minutes. After 30 minutes, they use the carbon
dioxide sensor to measure the amount of carbon dioxide produced by the crickets over a period of five
minutes.

Identical marbles are released from the same height on each of the following four frictionless ramps . compare the speed of the marbles at the end of each ramp. explain your reasoning

Need asap ! what is the relationship between atmospheric pressure and the density of gas particles in an area of increasing pressure? (2 points) as air pressure in an area increases, the density of the gas particles in that area decreases. as air pressure in an area increases, the density of the gas particles in that area increases. as air pressure in an area increases, the density of the gas particles in that area remains constant. as air pressure in an area increases, the density of the gas particles in that area increases and decreases in an alternating pattern. 3. which of the following correctly describes a way in which earth's atmosphere interacts with the geosphere? (2 points) it contains gases that living organisms breathe. it contains gases that trap incoming solar radiation. it provides a medium for cycles that provide nutrients to living organisms. it provides a medium for water to move between earth's surface and the air. 4. which of the following is considered a drawback to using wind energy as a source of power? (2 points) wind energy is nonrenewable. wind energy produces large amounts of air pollution. 5. a meteorologist predicts that the weather in a region will soon change from clear skies to probable thunderstorms. prior to making this prediction, what did the meteorologist most likely observe on a barometer? (2 points) the barometer fell slightly. the barometer fell substantially. the barometer rose slightly. the barometer rose substantially. 6. which of the following do meteorologists not typically use weather balloons to record? (2 points) atmospheric pressure cloud types humidity temperature 7. during which step in the can crush lab did water vapor force air from the can? (2 points) the can was filled nearly to the top with water. the can was placed on the hot stove top burner for several minutes. the can was removed from the hot stove top burner. the can was placed upside-down in the water-filled pan.
