They move by osmosis(a process by which molecules of a solvent tend to pass through a semipermeable membrane from a less concentrated solution into a more concentrated one.).
If the scientists are studying the effects of different temperatures on the processing speed of a computer chip then they would need to know the temperature inside the computer.
However, your questions doesn't include the full question text, so I cannot be sure what answer you need.
If the question is what do they need to know to do this, the answer is C.
If the question is how could they measure this when they subject the computer to different temperatures, then the answer is D.
Answer:
(c). are gaps between neurons where chemical signals are used to transmit information
Explanation:
Synapses can be defined as junction present between two nerve cells, through which nerve impulses are transmitted by using chemical signals or neurotransmitters. The synapses represent a small gaps that separate two neurons.
The neurotransmitters are released by ending of presynaptic neuron and allows transmission of signals from presynaptic neuron to postsynaptic neuron. Hence, synapses are necessary for unidirectional flow of impulses.
Thus, the correct answer is option (c).
