Facilitated diffusion is usually significant to pass the ions across the hydrophobic layer of the plasma membrane. Transmembrane integral protein and careers proteins provide the channels that allow the ion to pass across the membrane. When an ion bind to their active site on the protein (note that the proteins are very selective), the protein changes conformation. It is this change in conformation opens up the channel that allows the ions to be passed across the membrane. When the ions are released inside of the cell, the protein resumes normal shape (and the channel also closes) and the active site becomes available again or another ion.
Answer: C. 82.26%
Explanation:
Given : The red blood cell counts of women are normally distributed with
Let X be the random variable that represents the red blood cell counts of randomly selected woman.
Z-score : 
For X=4.2
For X=5.4
Now, the probability that the women have red blood cell counts in the normal range from 4.2 to 5.4 million cells per microliter will be :-
Hence, 82.26% of women have red blood cell counts in the normal range from 4.2 to 5.4 million cells per microliter.
They stay in deeper warmer water and move allot and eat a lot of bait food
all of the above should be noted for the coroner. because the authorities are trying to solve a homicide.
