Answer:
B. the human brain can only create signals
Answer:
<em>It is the outermost covering of a cell that separates the contents of the cell from its external environment. </em>
<em />
<em>It only allows the entry and exit of some materials. It also prevents the movement of some. Therefore, it is also called a selectively permeable membrane.</em>
<em />
<em>Some substances like carbon dioxide and oxygen can move across the cell membrane due to the process known as diffusion.</em>
<em />
<em>Water also obeys the laws of diffusion. The movement of water molecules through a selectively permeable membrane is called osmosis.</em>
<em />
<em />
<em>Pls mark as brainliest.</em>
The answer is D
Consulting their chemistry teacher and other students in class would not be in depth enough, so A and B are not the answers.
While consulting a chemistry textbook will be useful, the scientific journal is not the best choice.
However, the chemistry textbook would be great, and the periodic table of elements os necessary if they are doing a study about it so the best answer would be D.
Hope this helps!
Water is made up of hydrogen and oxygen. While underwater the water molecules glide and some stick to your body but they do not break off of your body until they are subjected to air which gives you the "wet" sensation.
So in other words if I am above water and spill some water on my arm then I am wet because it is interacting with the oxygen in the air. If my arm is underwater then it is not wet because it is constantly underwater and the water molecules are just gliding along my skin and it isn't until my arm is removed from the water that is becomes attached to my arm and makes it feel wet.
Water = wet when above water but when submerged in water then water doesn't necessarily equal wet.
