A slice of cheese is 3.0°C and is sitting on a dish that is 3.0°C. If the dish and cheese are in a refrigerator that is set to 3.0°C, which of the following statements is true? (1 point)
Responses
Heat will not flow because there is no temperature difference between the substances.
The temperature of the air in the refrigerator will decrease and the temperature of the cheese will increase.
The temperature of the cheese will increase and the temperature of the dish will decrease.
Heat will flow from the air in the refrigerator to the cheese and the dish.
Heat will not flow because there is no temperature difference between the substances.

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)
Responses
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 invasion by non-native species competing for resources.
extinction is directly related to human impact.
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 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 waves would arrive at point B before they arrived at point A.
