D. Polarity and size.
<span>The size, polarity, and charge of a substance will determine whether or not the substance can cross the cell membrane by diffusion. The cholesterol was an example of a lipid, and is highly soluble in the nonpolar environment of the lipid bilayer. You saw, in the animation above, the cholesterol freely passing into the hydrophobic environment of the membrane. Cholesterol distributes freely in the membrane and then some fraction will dissolve in the aqueous environment of the cytoplasm. Water, on the other hand, while polar, is small enough to cross the membrane at a slow rate. Note that specialized transport proteins in certain cell membranes can provide a channel for the water, greatly increasing its rate of crossing the membrane. The lipid bilayer is much less permeable to the ion, because of its charge and larger size. As a general rule, charged molecules are much less permeable to the lipid bilayer.</span>
I think the answer to your question is q
A
The nurse should explain the newly diagnosed lung cancer client that the reason why his tumor metastasized so fast without displaying many signs/symptoms is that: the malignant tumors affect area tissues by releasing enzymes and toxins that make the other normal cells to differentiate uncontrollably.
Metastasis is the property of spreading of cancer cells. When the tumor at a location in the body starts spreading top other locations as well, it is said to be metastasizing.
Malignant tumors are those that metastasize. They travel to near or distant locations at the body and start dividing. These are cancerous in nature.
