The correct statement is: heat will not flow because there is no temperature difference between the substances.
Is that correct?
My apologies for the repetition in my previous responses. The correct statement is: heat will not flow because there is no temperature difference between the cheese and the dish, as well as the air in the refrigerator.

The brightness of a star depends on how much light is released by the star and how far the star is from Earth. There are two ways to describe a star's brightness. A star's Response area brightness is the brightness seen by humans on Earth. A star's Response area brightness is its actual brightness and does not depend on where the star is viewed from.
The brightness of a star depends on how much light is released by the star and how far the star is from Earth. There are two ways to describe a star's brightness. A star's apparent brightness is the brightness seen by humans on Earth. A star's absolute brightness is its actual brightness and does not depend on where the star is viewed from.

Thousands of golden toads, shown below, used to occupy the tropical forests of Costa Rica. In the late 1980s, however, unusually warm weather caused many of the pools that the toads used as breeding areas to dry up. By 2004, the golden toad was listed as extinct. This example demonstrates how:(1 point)

extinction is caused by bacteria, fungi, and other infectious agents.
extinction is caused by bacteria, fungi, and other infectious agents.
extinction can be related to a failure to adapt to changes in the environment.
extinction can be related to a failure to adapt to changes in the environment.
extinction can be related to invasion by non-native species competing for resources.
extinction can be related to invasion by non-native species competing for resources.
extinction is directly related to human impact.
The example of the golden toad becoming extinct demonstrates how extinction can be related to a failure to adapt to changes in the environment.

The following image is a prediction of how an earthquake would spread from the epicenter (marked by a star). Red indicates the worst areas, and green indicates the places where there is the least shaking. Water is colored blue. Consider a seismic wave—an earthquake—that starts in the middle of the red area and travels outward along the surface of the earth. Point A is the same distance from the epicenter as point B. Using what you know about the movement of waves, how would you expect the seismic waves to be different at point A and point B?(1 point)
Responses
The waves would be larger at point A than at point B.
The waves would be larger at point A than at point B.
The waves would be exactly the same at points A and B.
The waves would be exactly the same at points A and B.
The ground would shake up and down at point A but back and forth at point B.
The ground would shake up and down at point A but back and forth at point B.
The waves would arrive at point B before they arrived at point A.
Based on the information provided, the correct response is: The waves would be exactly the same at points A and B.

Remy has learned that rock and soil from avalanches can cause tsunamis by falling into the ocean. Remy wonders if the height of the mountain has anything to do with the eventual size of the tsunami wave. How should Remy test this?(1 point)
Responses
Build different-sized model mountains at the edge of a pool, pour sand down the side of each mountain, and see how large each resulting wave is.
