The primary function of a neuron is to receive messages from the senses and then respond with motor activity such as a finger being burnt and thpe arm muscle pulling the finger out of harms's way. So safety is part of it. Another function is to use sensory neurons to evaluate a scientific understanding of the world, such as determining which mineral is being looked at ie by its' colour, hardness, crystal system etc.

A red blood cell placed in a hypertonic solution will shrink in a process called crenation. A red blood cell placed in a hypoton
-BARSIC- [3]

Answer:

The correct answers are A. "crenation", B. "hemolysis", C. "hemolysis", D. "crenation" and E. "neither will occur".

Explanation:

0.9% (m/v) NaCl or 5.0% (m/v) glucose are isotonic solutions at which the cells will not suffer any harmful consequence. A solution with a higher concentration than the isotonic conditions would result in the cells crenation, while a solution with a lower concentration would result in the cells hemolysis. Therefore the consequences of putting the red cells to the solutions stated in the question are as following:

A: 3.21% (m/v) NaCl Solution  = crenation (higher than 0.9% (m/v) NaCl)

B: 1.65% (m/v) glucose Solution  = hemolysis (lower than 5.0% (m/v) glucose)

C: distilled H2O Solution  = hemolysis (lower than 0.9% (m/v) NaCl or 5.0% (m/v) glucose)

D: 6.97% (m/v) glucose Solution  = crenation (higher than 5.0% (m/v) glucose)

E: 5.0% (m/v) glucose and 0.9%(m/v) NaCl = neither will occur (equal to 5.0% (m/v) glucose and 0.9% (m/v) NaCl)
