The question is incomplete. So the complete question and answer are given below:
You are talking with a friend in a closed room that has no windows, no objects, and no furniture. The only thing in the room is an overhead incandescent light that is turned on. You are looking at your friend and begin thinking about whether you are seeing your friend as a result of reflection. Does reflection play a role in seeing your friend? Group of answer choices:
Yes, the visible light from the overhead light bulb is diffusely reflected from my friend and enters my eye.
Reflection is the change in direction of the wavefront at the interface between two different media such that the wavefront returns to the medium of origin. Common examples are the reflection of light, sound, and water waves. According to the law of reflection, in specular reflection (such as from a mirror), the angle at which the wave hits the surface is equal to the angle at which it is reflected.
In acoustics, reflections cause echoes and are used in sonar. In geology, it is important for the study of seismic waves. Reflections are observed in surface waves in water bodies. Reflections are seen in many electromagnetic waves besides visible light. Reflections from VHF and higher frequencies are important for radio transmission and radar.

It would be D) carbon dioxide (I took the test haha).
Answer: The main ingredient of cells is water. Water is needed to maintain homeostasis. Cells are also made up of macromolecules—nucleic acids, lipids, proteins, carbohydrates. These macromolecules help maintain a cell's structure, help cells communicate with each other, aid in energy storage, etc.
Purpose of the Berlin Conference
In 1884 at the request of Portugal, German chancellor Otto von Bismark called together the major western powers of the world to negotiate questions and end confusion over the control of Africa. Bismark appreciated the opportunity to expand Germany's sphere of influence over Africa and desired to force Germany's rivals to struggle with one another for territory.
At the time of the conference, 80% of Africa remained under traditional and local control. What ultimately resulted was a hodgepodge of geometric boundaries that divided Africa into fifty irregular countries. This new map of the continent was superimposed over the one thousand indigenous cultures and regions of Africa.
