<span>Membrane permeable to a liquid (solvent) and impermeable (or poorly permeable) to substances dissolved in the liquid (solute). It can be natural or synthetic.
Depending on the membrane and solute, the permeability may depend on the size, solubility, properties, or chemical composition of the solute itself.
If molecules are small enough, then it can pass through the semi-permeable membrane, because the permeability is </span>inversely proportional to the molecule size.
<span>For example in hemodialysis, electrolytic equilibrium and toxics' elimination are performed by subjecting the patient's blood to the dialysis physical principle. It is made to slide in a filter in which it comes in contact with a semi-permeable membrane through which pass only or at least in a greater quantity of toxic substances) that you want to remove.</span>
Answer:
A. Natural killer (NK) cells are activated in response to interferons or macrophage and Major histocompatibility complex (MHC) and allows direct apoptosis of virus.
Viruses can invade NK cells by inhibiting MHC from reaching the cell surface. Using stimulating the inhibitory receptors and disrupting the activating receptors, viruses can avoid NK cells. MHC act as a ligand of inhibitory receptor, and when bind with inhibitory receptor allows damage to NK cells.
So, if i would be a virus i will use inhibitory receptors stimulation to avoid NK cells.
B. Bacteria are killed by phagocytic immune cell macrophages by engulfing them.
Bacteria avoid macrophages by escaping from phagosome before the lysosome fuses as lysosomal chemical kill the bacteria and some bacteria prevent acidification of the phagosome.
C. Parasites can avoid macrophages by modulating the host's cell cytoskeleton to block proper phagocytosis.
D. Bacteria can avoid dendritic cells by avoiding lysosomal degradation and prevent antigen presentation on MHC molecules that will modulate the entrance to DCs.
E. B cells are responsible for producing antibodies. Activation of B-cell depends on positive and negative signals transmitted through the B-cell receptor (BCR), so genetic polymorphisms and mutations affects the positive and negative signals. If mutation is done showing negative signal, B cell will not the activate and no antibodies will produce.
Hollow, that's why birds can fly. There is nothing in the bone to weigh them down.
Organism is the smallest unit of organization.
