Im desperate please help Question 2 To prepare for the experiment, follow these steps:

Put one or two ice cubes in 1 cup of water. Chill the cup of water in the refrigerator for 1 to 2 hours. Remove any remaining ice when you take the water out of the refrigerator. This cup holds the ice-cold water.
Heat up three cups of water in the microwave for 15 to 20 seconds until they reach 100°F on the thermometer. If you heat the water too much, wait until the temperature drops to 100°F. These cups hold the lukewarm water.
Heat the last cup of water in the microwave until it reaches 212°F. This cup holds the boiling water.
Now line up the five glasses and label them A, B, C, D, and E. Then put the following contents in each glass:

Take measurements of the foam level every 15 minutes for 60 minutes. Record your measurements in the table.

a plastic spoon that has a temperature of 78° f is placed into a bowl of soup that has a temperature of 84° f. which of these correctly describes what will happen?

energy as heat moves from the soup to the spoon.

the two answers are a, the population of birds with large beaks will increase on the island, and c, the trait for large beaks will be passed on to future generations through natural selection. the reason for that is because if the birds that have beaks developed for eating small seeds lose all of their food, they will go hungry and eventually starve because they physically cannot eat the large seeds, therefore making the population of large beaked birds higher. also, if the trait of large beaks are dominant on the island over small beaks, then over time the large beaked birds will reproduce more and more, while the smaller beaked birds will reproduce less and less because they can't survive with the food provided. that leads to the trait of small beaks disappearing and the trait of large beaks taking over the island.

it provides an alternative energy pathway for the reaction to proceed.

a catalyst is a substance that speeds up the rate of a chemical reaction but is not consumed during the course of the reaction.

catalysts increase the rate of reaction without being used up. they do this by lowering the activation energy needed. with a catalyst, more collisions result in a reaction, so the rate of reaction increases. different reactions need different catalysts.

a catalyst works by providing an alternative reaction pathway to the reaction product. the rate of the reaction is increased as this alternative route has a lower activation energy than the reaction route not mediated by the catalyst.
