Q: Answer the following question given this paragraph: Even if you don't live in a place where leaves turn color in the fall, no doubt you've seen photos of their "fall colors" (see Figure below ). The leaves of many plants turn from green to other, glorious colors during autumn each year. The change is triggered by shorter days and cooler temperatures. Leaves respond to these environmental stimuli by producing less chlorophyll . This allows other leaf pigmentssuch as oranges and yellowsto be seen. Q: When plants lose their leaves in the fall, what chemical is produced less to cause the change? Choices: - pheromes - carbonate - oxygen - chlorophyll A:
A: chlorophyll
Question: Answer the following question given this paragraph: Sulfate minerals contain sulfur atoms bonded to oxygen atoms. Like halides, they can form in places where salt water evaporates. Many minerals belong in the sulfate group, but there are only a few common sulfate minerals. Gypsum is a common sulfate mineral that contains calcium, sulfate, and water. Gypsum is found in various forms. For example, it can be pink and look like it has flower petals. However, it can also grow into very large white crystals. Gypsum crystals that are 11 meters long have been found. That is about as long as a school bus! Gypsum also forms at the Mammoth Hot Springs in Yellowstone National Park, shown in Figure below . Q: What two types of atoms bond to form sulfate minerals? Choices: - oxygen and carbon - oxygen and calcium - carbon and sulfur - oxygen and sulfur A:
Answer: oxygen and sulfur

(Q).
Answer the following question given this paragraph: When a new air mass moves over a region it brings its characteristics to the region. This may change the area's temperature and humidity. Moving air masses cause the weather to change when they contact different conditions. For example, a warm air mass moving over cold ground may cause an inversion. Q: An inversion may result when what kind of mass moves over cold ground? Choices: - warm water - cold water - cold air - warm air A:
(A).
warm air
