The Ship - Complete Pack (Scientific Puzzle)

1 is annoying me for some reason. I know what it is, but I can't seem to find the right word.

3 would be fairly easy to find. I mean, at least that part of biochem is well structured :p Finding the name would be relatively easy if you knew the name of the smaller components.

5 I feel like I've heard before, but couldn't find it even on Google. Must be some kind of basic knowledge expression...

But well, tried it for fun, but already have The Ship, so good luck for the others who'd try it! And thanks for the giveaway!

"Even" a biologist? :(

thanks :)

"Vanadium is a chemical element with the symbol V and atomic number 23. It is a hard, silvery gray, ductile and malleable transition metal. The element is found only in chemically combined form in nature, but once isolated artificially, the formation of an oxide layer stabilizes the free metal somewhat against further oxidation. Andrés Manuel del Río discovered compounds of vanadium in 1801 by analyzing a new lead-bearing mineral he called "brown lead," and presumed its qualities were due to the presence of a new element, which he named erythronium (Greek for "red") since, upon heating, most of its salts turned from their initial color to red."
