I would go with B) Nerves in the finger detect stimuli and send the message to the brain.
The protective covering of the brain
that provides passageways for cerebrospinal fluid (CSF) to drain into the
superior sagittal sinus is called the arachnoid mater.
To add, the arachnoid mater is the middle
of three layers that make up the meninges, or membranes, that surround the spinal
cord and brain.
I'm not sure if you needed a translation or an answer but i'll give both:)
"Why is it that in some countries it is day while in others it is night"
because at different times of the day the sun hits different areas of the earth. I hope this helps!

Answer:
The correct answer would be the active transport across the cell membrane.
The main functions of the cell membrane are a barrier, regulates transport (passive, facilitated, and active), the presence of receptors et cetera.
Only active transport (such as sodium pump, calcium pumps et cetera) requires the input of energy (ATP) for proper functioning. It uses energy to pump substances against the concentration gradient.
Thus, only active transport would be affected if less cellular energy is available.
Proteins serve as antibodies.
