Is it possible to build a cost effective artificial leaf

answer:

for years, scientists have been pursuing “artificial leaf” technology, a green approach to making hydrogen fuel that copies plants’ ability to convert sunlight into a form of energy they can use. now, one team reports progress toward a stand-alone system that lends itself to large-scale, low-cost production. they describe their nanowire mesh design in the journal acs nano.

explanation:

the answer would be d

starchy vegetables are high in carbohydrates.

starchy vegetables contain more carbohydrates than non-starchy vegetables.

explanation:

there are two primary categories of carbohydrates, essentially differentiated on the basis of their carbohydrate content (which is in the form of starch - a complex carbohydrate):
