The diagram shows Earth at different positions as it orbits the sun.
What differences between Earth’s Northern and Southern Hemispheres are represented in the diagram, AND what causes these differences?
The diagram shows that the Northern and Southern Hemispheres experience different seasons at the same time. This seasonal difference is due to Earth’s tilt on its axis as it orbits the sun. As a result, one hemisphere is angled toward the sun and experiences summer, while the other is tilted away and experiences winter.
The diagram shows that when it is summer in one hemisphere, it is also summer in the other. This seasonal difference happens because both hemispheres receive the same amount of sunlight throughout the year.
The diagram shows that seasons are caused by the Earth getting closer to and farther from the sun during its orbit, leading to changes in temperature in both hemispheres.
The diagram shows that Earth’s rotation on its axis creates the seasons, with each hemisphere experiencing the same weather patterns as a result.

There are many different species of rat snakes in the United States. Three species are described in the table.
These species are similar but have different color patterns.
Which statement BEST explains these differences in color?
Each snake population adapted to a different environment over time.
Each snake population moved to a different environment to reproduce.
Each individual snake changed its color to match its environment.
Each individual snake chose the best colors to pass to its offspring.

An energy pyramid is shown.
Which statement BEST describes the flow of energy through this pyramid?
Producers provide energy directly to the organisms in all the trophic levels above them.
Primary consumers transfer energy to the trophic level above them and the trophic level below them.
Secondary consumers represent the most organisms, and they have the greatest amount of energy in their trophic level.
Tertiary consumers do not receive all the energy from the trophic level below them, because some energy is lost to the environment.

- Q12
A group of students was conducting an investigation with plants. One group of plants was placed inside a closet. The other group of plants was placed next to a window. After two weeks, the plants next to the window were taller and healthier than the plants in the closet.
Which statement BEST explains the difference in plant growth?
The plants next to the window were able to convert more light energy into chemical energy.
The plants next to the window were able to convert more thermal energy into light energy.
The plants next to the window were able to convert more thermal energy into mechanical energy.
The plants next to the window were able to convert more light energy into electrical energy.

Multicellular, heterotrophic organisms that have a nucleus are members of Kingdom Animalia.
Multicellular, autotrophic organisms that do not have a nucleus are members of Kingdom Archaea.
