The linear mass density can then be understood as the derivative of the mass function with respect to the one dimension of the rod (the position along its length =) The SI unit of linear mass density is the kilogram per meter (kg/m). Linear density of fibers and yarns can be measured by many methods.
An Arabidopsis thaliana chlorophyll(ide) a oxygenase gene (cao), which is responsible for chlorophyll b synthesis from chlorophyll a, was introduced and expressed in a photosystem I-less strain of the cyanobacterium Synechocystis sp.
The graph indicates that A) green light is strongly absorbed by chlorophyll B) blue light is reflected by the cartenoid C) yellow light is absorbed by caroteinoid D) red light and blue light are absorbed by chlorophyllE) red light is absorbed by the caroteinoid.12.arbohydrate-synthesizing reactions of photosynthesis directly requireA) lightB) products of the light reactionsC) darknessD) O 2 and H 2 OE) chlorophyll and CO 2 20. Carbon dioxide is passed into a solution of bromothymol blue indicator until the acid solution turns yellow.
