What is the value of a Michael Jordan scoring hologram basketball card?
It completely depends on the condition of the card and which year's item it is. The 1996-97 holograms from Upper Deck merely values around $10-50. However, The Michael Jordan 1991 Upper Deck Framed 4 Card Uncut Hologram Aw1 Aw4 is priced around $225. Check out online auction listings and also you can subscribe to Basketball Online Price Guide to understand the basketball card pricing trend.
What does buffer aw1 and aw2 do?
Buffer AW1 contains Guanidinium Chloride (guanidine hydrochloride). This is used to denature proteins in your sample. They will then flow through the column and will be discarded with the wash. Buffer AW2 is essentially 70% EtOH. 30 mls of 100% EtOH is added to the 13 mls of "concentrate"included in the bottle. 70% EtOH is used to remove salts from your column and aid in purifying your DNA.
How to proof the distributive law in vectors?
If we're talking vectors in a vector space, then distributivity is taken as an axiom. We can prove it for vectors in Rn, therefore (partially) proving that our common notion of vectors actually satisfies the axioms of a vector space. Below, a and b are scalars and v and w are vectors. a(v+w) = a( (v1, ..., vn) + (w1, ..., wn) ) = a(v1+w1, ..., vnwn) = (a(v1+w1), ..., a(vn+wn)) = (av1+aw1, ... , avn+awn) = (av1, ..., avn) + (aw1, ..., awn) = av+aw (a+b)v = (a+b)(v1, ..., vn) = ((a+b)v1, ..., (a+b)vn) = (av1+bv1, ..., avn+bvn) = (av1, ..., avn) + (bv1, ..., bvn) = av+bv
