Answer

1. # Brief Explanations: An object is in motion when its position, distance, or direction changes with respect to a point of reference. These are all valid ways to define motion. # Answer: D. I, II and III only 2. # Brief Explanations: The male athletes have shorter recorded times for the 200 - meter dash, so they are faster. The fastest male athlete has a time of 21.9 s and the fastest female athlete has a time of 25.3 s, so the average speed of the fastest female athlete is less than that of the fastest male athlete. # Answer: C. Both I and II 3. # Brief Explanations: Speed is calculated as distance divided by time. Here the distance is 200 meters and time is the recorded time of travel. # Answer: B. Divide 200 meters by the recorded time of travel. 4. # Brief Explanations: Sound is produced by vibrating objects. Soft objects and objects under pressure don't necessarily produce sound, and radio - stations transmit electromagnetic waves not sound directly. # Answer: C. Vibrating objects 5. # Brief Explanations: In the ROYGBIV spectrum, blue has a shorter wavelength and higher frequency among the given options, and higher frequency light has more energy. # Answer: A. Blue 6. # Brief Explanations: When an appliance "uses up" electricity, the potential energy of electrons is converted into another form like heat, light or mechanical energy. # Answer: D. The potential energy of electrons is changed into another form. 7. (No information about setups A, B, C is given, so unable to answer this question) 8. # Brief Explanations: The layers of the atmosphere are divided based on changing temperature. # Answer: A. Changing temperature 9. # Brief Explanations: Most water vapor is found in the troposphere, the lowest layer of the atmosphere where weather occurs. # Answer: A. Troposphere 10. # Brief Explanations: The air temperature decreases with altitude, so hikers put on thicker clothes to keep warm. # Answer: B. The air temperature decreases with altitude 11. # Brief Explanations: The correct order of Earth's atmospheric layers from bottom to top is Troposphere—Stratosphere—Mesosphere—Thermosphere—Exosphere. # Answer: D. Troposphere—Stratosphere—Mesosphere—Thermosphere—Exosphere 12. # Brief Explanations: Tropical rainforests are typically located near the equator (0° latitude). # Answer: A. 0° latitude For the first question about first - order consumers: # Brief Explanations: A first - order consumer is an organism that eats producers. Rice is a producer, a bird eats rice (a producer), so the bird is a first - order consumer. A hawk eats the bird (a first - order consumer) so it is a second - order consumer, and a python can also be a higher - order consumer. # Answer: B. BIRD
