() a sodium-potassium pump within a cell membrane requires energy to move sodium and potassium ions into or out of a cell. the movement of glucose into or out of a cell does not require energy. which statement best describes the movement of these materials across a cell membrane? 1points a sodium and potassium ions move by active transport, and glucose moves by osmosis. b sodium and potassium ions move by active transport, and glucose moves by facilitated diffusion. c sodium and potassium ions move by facilitated diffusion, and glucose moves by osmosis. d sodium and potassium ions move by facilitated diffusion, and glucose moves by active transport.

hey bro i looked it up on google the structure of the eye-spot in euglena viridie, e. ehrenbergii, and phacus pyriyorme is not as franzé haa described it. the so-called “crystal body” and “lens bodies” were not found in any of the individuals of the species examined by me. as earlier observers have stated, the eye-spot consists simply of a mass of pigment granules arranged in a single layer, and probably embedded in a protoplasmic framework, but the latter could not be seen, and its presence was only inferred from the fact that the pigment granules must be held together in some way, thd the eye-spot as a whole is capable of expansion, and that the pigment granules can be separated from each other.

hope this   and an i get brainlsiest
