Active transport because the movement of molecules is going across the cell membrane (that should be right?)
Answer: This is because a parent with type AB blood has both A and B antigens therefore, the child must inherit either A or B antigen from the parent.
Explanation: In ABO blood type, blood types are classified on the basis of the antigens present in the red blood cells. There are two types of antigens: A and B antigens.
A blood type is so named because it has A antigens, B blood type has B antigens, AB blood type has both A and B antigens while O blood type has no antigens.
Each of these blood types is controlled by two alleles, and children inherit one allele from each parent. If a parent has AB blood type, none of his offsprings will have O blood type because each offspring must inherit either antigen A or B from this parent.
One way is that Igneous rock could erode and become sediment and deposited and slowly change into sedimentary rock, then get pushed down deep into the crust and changed by heat and pressure into metamorphic rock.
<span>This is an example of facilitated diffusion using a channel. Diffusion is the process of an object moving across a concentration gradient, usually from areas of higher to lower concentration in membranes. In this case, the diffusion is "facilitated" by the aquaporin molecules and water is allowed to enter or exit the membrane based on concentration level.</span>
