D. All three primary germ layers develop into some more type of nervous tissue
Explanation: All of the primary germ layers have specific nervous tissue development. a) Ectoderm - neuroectoderm (neural tube, neural crest). b) Endoderm develops into (among others): The digestive tract and its attached glands; the inner lining of some organs, such as the lungs, nervous tissue; epidermis . c) Mesoderm - notochord signals the ectoderm to develop the neural crest more
Osmosis describes the movement of water across a biological membrane and down its concentration gradient. In chemiosmosis, useful energy is harnessed by the cell from the movement of <u>ions</u> across the inner mitochondrial membrane into the matrix <u>intermemberane space</u> a concentration gradient.
