What do these two changes have in common? a slice of banana turning brown burning food on a stove

[ "Both are caused by cooling.", "Both are only physical changes.", "Both are chemical changes.", "Both are caused by heating." ]

C

Step 1: Think about each change. A slice of banana turning brown is a chemical change. The part of the banana in contact with the air reacts with oxygen and turns into a different type of matter. Burning food on a stove is a chemical change. When the food burns, the type of matter in it changes. The food turns black and gives off smoke. Step 2: Look at each answer choice. Both are only physical changes. Both changes are chemical changes. They are not physical changes. Both are chemical changes. Both changes are chemical changes. The type of matter before and after each change is different. Both are caused by heating. Burning is caused by heating. But a slice of banana turning brown is not. Both are caused by cooling. Neither change is caused by cooling.

Use the arrows to follow how matter moves through this food web. For each answer choice, try to find a path of arrows that starts from the bilberry.There is one path matter can take from the bilberry to the short-tailed weasel: bilberry->brown lemming->short-tailed weasel. lichen. The lichen does not have any arrows pointing to it. So, in this food web, matter does not move from the bilberry to the lichen.. barren-ground caribou. The only arrow pointing to the barren-ground caribou starts from the lichen. The lichen does not have any arrows pointing to it. So, in this food web, matter does not move from the bilberry to the barren-ground caribou.. There are two paths matter can take from the bilberry to the Arctic fox: bilberry->Arctic fox. bilberry->brown lemming->Arctic fox. bear sedge. The bear sedge does not have any arrows pointing to it. So, in this food web, matter does not move from the bilberry to the bear sedge..

What do these two changes have in common? baking an apple pie a sidewalk heating up in the sun

[ "Both are caused by heating.", "Both are only physical changes.", "Both are caused by cooling.", "Both are chemical changes." ]

A

Step 1: Think about each change. Baking an apple pie is a chemical change. The type of matter in the pie changes. The apples become soft, and the crust turns brown. A sidewalk heating up in the sun is a physical change. The temperature of the sidewalk goes up, but the sidewalk is still made of the same type of matter. Step 2: Look at each answer choice. Both are only physical changes. A sidewalk heating up in the sun is a physical change. But baking a pie is not. Both are chemical changes. Baking a pie is a chemical change. But a sidewalk heating up in the sun is not. Both are caused by heating. Both changes are caused by heating. Both are caused by cooling. Neither change is caused by cooling.

What do these two changes have in common? a banana getting ripe on the counter plants making food from sunlight, air, and water

[ "Both are caused by heating.", "Both are only physical changes.", "Both are caused by cooling.", "Both are chemical changes." ]

D

Step 1: Think about each change. A banana getting ripe on the counter is a chemical change. As a banana ripens, the type of matter in it changes. The peel changes color and the inside becomes softer and sweeter. Plants making food is a chemical change. Plants use energy from sunlight to change air and water into food. The food is sugar. Sugar is a different type of matter than air or water. Step 2: Look at each answer choice. Both are only physical changes. Both changes are chemical changes. They are not physical changes. Both are chemical changes. Both changes are chemical changes. The type of matter before and after each change is different. Both are caused by heating. Neither change is caused by heating. Both are caused by cooling. Neither change is caused by cooling.
