In which sol ution is the solute concentration greater than the ICF of the red blood cell? 20. If a cell is placed in a(n) 21. The osmolarity of non-permeable solutes is equivalent to the ICF of a red blood cell. solution, over a period of time the cell would crenate. Questions 22-25. Answers the following questions based on the atomic model below 11 pt 12 n° 22. Atomic number is 23. Atomic mass is 24. Does the model represent an atom, cation, or anion? 25. For question #24, explain your answer?Explanation / Answer
19.
In a hypertonic solution, solute concentration is greater than the ICF of the RBC.
20.
If a cell is placed in hypertonic solution, water moves out of the cell leading to cell shrinking/crenation.
21.
In ISOTONIC solutions, the osmolarity of the non-permeable solutes is equivalent to the ICF of an RBC.
22.
Atomic number = Number of protons = 11
23.
Atomic mass = Number of protons + Number of neutrons = 11 + 12 = 23
23.
Number of protons = 11
Number of electrons = 10
Net charge = 11 - 10 = +1
So, it is a cation.
24.
Cation = +ve charge (More number of protons than electrons)
Anion = -ve charge (More number of electrons than protons)
Neutral atom = No charge (Equal number of protons and electrons)
