I am missing manufacturer’s label on my screendoor. Can’t identify the door handle it needs. How can I open

this door with something else that can be used as a knob or handle? It’s a metal or aluminum screen door with the interchangable screen window at the top. It is not new. I have a railing on one side of the door and I taped a piece of wood there so the door doesn’t close so you can open it with your fingers.

describe one advantage and one disadvantage of using barcode to identify species?

Best answer:

one advantage would be everything would be organized to shit i mean one scan then that goes to computer that catergorizes everything, and everything could be broken down of that species. Its heritage its descentants, etc. but then you have the complete opposite when it comes to now our species because i know for shit sure your not putting a barcode on me, and i’m sure im not the only one thinkning that. Also would you really want to pay over a thousand people for the next twenty to thirty years to go around organizing all this information and labeling every last more thing on this planet. End result i say screw barcodes look stuff up you want to know somthing about something look it up and learn, people are to lazy these days, you just want to scan somthing and get the answer and cut out the middle man. Ya brain homie

Best answer:

I purchased a cake carrier from ebay. the seller cut the manufacturer info off of the label and I would like to get other pieces which this particular seller does not offer so I’d like to find out who the manufacturer is. the seller did leave the bar code intack and i understand that the first 6 numbers (in this case 078652) identify the manufacturer.

Best answer:

You can look up a product by its UPC barcode or number translation at the following website.
