The diagram above shows the repeating groups of atoms that make up two samples. Both samples are liquid at room temperature. Will the properties of the two samples likely be the same or different? (Examples of properties are smell, color, and the temperature at which a substance melts.)

• The properties will likely be the same because the repeating groups of atoms that make up the two samples have the same types of atoms..

• The properties will likely be the same because both samples are liquids at room temperature.

• The properties will likely be different because the repeating groups of atoms that make up the two samples have different numbers of atoms.

• The properties will likely be different because there are more repeating groups of atoms in Sample 1.

The size of the sardine population will . . .

• stay the same. The size of its resource population did not change, so the amount of energy storage molecules available for the sardines did not change. There will be the same number of births and deaths in the sardine population.

• decrease. A decrease in one population causes a decrease in the sizes of all other populations in the ecosystem.

• increase. The smaller penguin population will leave more energy storage molecules available for the sardine population to reproduce more. This will lead to more births in the sardine population.

• increase. The smaller penguin population will need fewer energy storage molecules, so they will eat fewer sardines. This will lead to fewer deaths than births in the sardine population.

These goats are eating grass on a sunny day. What is happening to the carbon in the air around the living things on the mountain? Is carbon moving into the air, moving out of the air, or both?

• Carbon is only moving into the air; it is not moving out of the air.

• Carbon is moving into the air and out of the air at the same time.

• Carbon is not moving into the air; it is only moving out of the air.

• With this information, there is no way to know for sure.
