Explanation:
An autoimmune disorder occurs when the body sees it's own cells as foreign antigens and begins to attack them.
The treatment depends on the particular autoimmune disorder; however, the mainstay of treatment is the use of IMMUNOSUPPRESSIVE MEDICATION. Examples include corticosteroids (such as prednisone) and nonsteroid drugs such as azathioprine, cyclophosphamide, mycophenolate, sirolimus, or tacrolimus.
Answer:
The periodic table of elements arranges all of the known chemical elements using this method. Elements are arranged from left to right and top to bottom in order of increasing atomic number. Order is usually according with the increasment (Is this a word?) of the atomic mass.
Explanation:
Have a good day :)
I'd say A: tidal waves. B, C, and D don't really seem to fit for me.
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>
Answer:
the correct oprtion is B
Explanation:
the correct answer is b, since increasing the porosity of the contact lens allows it to work as a good method of gas exchange, simulating the lung membranes that present fenestrated capillaries that promote gas exchange. For this to happen, the permeability must always be high and therefore this is directly related to the porosity of the element with which the contact lens is made.
