Nope!

Answer 5

Not all spiders have a red mark.  Not even all black widows have one.  Black widows vary in color from brown to dark red to black.  Some have no red marking, some have a red spot, some have a broken or lopsided hourglass shape, some have more of an anvil shape, some have only a perfect red hourglass, and others will also have red spots or stripes.  There can also be streaks of brown or grey.  However, if it's a black spider with a single red marking on the underside of its abdomen, it is almost certainly a black widow.

If it's dead though, it doesn't really matter because dead spiders don't bite.  :)

Answer 6

Some do, most don't.

Not all black widows have a red hourglass, this is a common misconception.
