D. Dalton

B. Mendeleev is the scientist who worked with decks of cards to develop the arrangement of  elements on the periodic table

Explanation:

The scientist who worked with the deck of cards to develop the arrangement of elements on the periodic table is Mendeleev.

Mendeleev wrote the each element data on a card and arranged them in the order of the atomic weights. One more way is to group them with the cards of identical elements. After that he combined the two rules along with his cards of 63 elements that were found at that time, like increase in the atomic weight  in each row as well as the elements of identical properties arranged in columns.

regulation of gene expression. gene expression can be regulated by various cellular processes with the aim to control the amount and nature of the expressed genes. these regulatory proteins bind to dna and send signals that indirectly control the rate of gene expression
