What controls movement of materials in and out of the cell, and acts as a barrier between the cell and the environment?
Nucleus
Cell membrane
Cell wall
Nuclear membrane
Explanation
To answer this question correctly, we need to know the function of the following organelles:
The cell membrane controls movement of materials in and out of the cell, and acts as a barrier between the cell and the environment.
The cell wall protects the cell, and allows water, oxygen, and carbon dioxide into and out of the cell.
The nuclear membrane controls movement in and out of the nucleus.
The nucleus controls the cell's activities.
Cell membrane is the correct answer.

Select the main difference between the three types of rocks: sedimentary, metamorphic, and igneous.
How the rocks are formed
Where the rocks can be found
The age of the rocks
The texture of the rocks
Explanation
The main difference between the types of rocks is how the rocks are formed.
Sedimentary rocks are formed from small particles of materials, such as sand or pebbles.
Metamorphic rocks are formed from changes in heat and pressure under the earth's surface.
Igneous rocks are formed from magna cooling and hardening.
