Answer:
4. Absorb extra fluid between the cells
Explanation:
The nervous system (SN) is a complex system that acts to receive sensory information through nerves, transmit this information via the spinal cord and finally process it in the brain. The SN has three main roles: sensory input, processing and motor output. The SN can be divided into the central nervous system (composed of the brain and spinal cord), and the peripheral nervous system (composed of those nerves located outside the brain and spinal cord). Moreover, the extracellular fluid between the cells comprises four types of fluids: 1-intravascular fluid (blood), 2-interstitial fluid, 3--transcellular fluid and 4-cerebrospinal fluid. The excess of these fluids is absorbed by the capillaries of the lymphatic system.

every cell has work to do but different cells may have different jobs in multicellular organisms, cell with the same type of job often work together. These group of specialized cell from tissue in turn, tissue often group together to form larger units called organs the heart is an organ; so is the stomach.
Answer:
your answer is positive b
The right answer is facilitated diffusion.
Facilitated diffusion is a diffusion mechanism facilitated by membrane transporters. it's the spontaneous passage of molecules or ions (like the passive diffusion) through a biological membrane through transport molecules (unlike passive diffusion). This process does not consume energy (like the passive diffusion) and therefore does not involve active transportation.
