The correct answer is a semi-permeable membrane.
A semipermeable membrane refers to a layer, which only allows some of the molecules to pass through. A semipermeable membrane can be both artificial and biological. The speed of passage relies on the concentration, pressure, and temperature of the solutes or molecules on either side, as well as the permeability of the membrane to each solute.
On the basis of the solute and the membrane, permeability may depend on the size of the solute, properties, solubility, or chemistry. A semipermeable membrane illustrates a membrane, which permits some of the constituents to go through, while the selectively permeable membrane opts for the substances that pass through.
Answer:A chromosome is a DNA (deoxyribonucleic acid) molecule with part or all of the genetic material (genome) of an organism.
Explanation:
Enzymes break up water or H2O into electrons, H+ ions, & oxygen atoms. Electrons replace the "highenergy" electrons that were lost in the electron transport chain.<span>Oxygen is released and the H+ ions are also released. - So the first one would be A. splitting of water or H2O
and the second one is B :)
