Genes involved in production of abnormal red blood cells may have an abnormal sequence of bases (nucleotides), like inherited alteration in the gene for JAK2, a protein with enzymatic activity that's linked to the abnormal production of blood cells.
This is disproven by the study of cells due to plants don't grow food they making by using sunlight are and water and nutrients <em><u>from </u></em><em><u /></em><u />the soil so it cannot produce the soil due to this fact.
The answer is
Dominant Trail
By definition: Facilitated diffusion<span> is the process of spontaneous passive transport of molecules or ions across a cell's membrane via specific transmembrane integral proteins.~Google
An example, the only I can really think of:
Polar and large molecules normally can't cross the lipid bi layer using simple diffusion, it usually has to be </span>Facilitated diffusion
It is Acceleration.
Explanation: You can probably find it in the back of your book in the definition.
