Problem: In the dicotyledons, the bundles in the very young stem are arranged in an open ring, separating a central pith from an outer cortex. In each bundle, separating the xylem and phloem, is a layer of meristem or active formative tissue known as cambium. By the formation of a layer of cambium between the bundles (interfascicular cambium), a complete ring is formed, and a regular periodical increase in thickness results from the development of xylem on the inside and phloem on the outside. The soft phloem becomes crushed, but the hard wood persists and forms the bulk of the stem and branches of the woody perennial. Owing to differences in the character of the elements produced at the beginning and end of the season, the wood is marked out in transverse section into concentric rings, one for each season of growth, called annual rings.
What does the cambium separate?
The answer is the following: xylem and phloem

Problem: On 28 February 1476, Pope Sixtus IV, authorized those dioceses that wished to introduce the feast to do so, and introduced it to his own diocese of Rome in 1477, with a specially composed Mass and Office of the feast. With his bull Cum praeexcelsa of 28 February 1477, in which he referred to the feast as that of the Conception of Mary, without using the word "Immaculate", he granted indulgences to those who would participate in the specially composed Mass or Office on the feast itself or during its octave, and he used the word "immaculate" of Mary, but applied instead the adjective "miraculous" to her conception. On 4 September 1483, referring to the feast as that of "the Conception of Immaculate Mary ever Virgin", he condemned both those who called it mortally sinful and heretical to hold that the "glorious and immaculate mother of God was conceived without the stain of original sin" and those who called it mortally sinful and heretical to hold that "the glorious Virgin Mary was conceived with original sin", since, he said, "up to this time there has been no decision made by the Roman Church and the Apostolic See." This decree was reaffirmed by the Council of Trent.
What word substitution did he use in the authorization to appease all of the worshipers and view points when speaking of the inception of Mary ?
The answer is the following: but applied instead the adjective "miraculous" to her conception.

Problem: In May 2008, the National Archives announced a five-year agreement to digitize selected records including the complete U.S. Federal Census Collection, 17901930, passenger lists from 18201960 and WWI and WWII draft registration cards. The partnership agreement allows for exclusive use of the digitized records by Ancestry.com for a 5-year embargo period at which point the digital records will be turned over to the National Archives.
