Explanation:
Cells are the most basic unit of life made up of several organelles that perform various functions which enables the cell to exist.
An aggregation of cells is called a tissue. The bone is composed of several interconnected cells and tissues.
A bone heals when bone cells and tissues are gradually repaired. Hence, the most basic levels of organization involved when a bone heals are cells and tissues.

Answer:
Chromatin helps regulate DNA replication.
Explanation:
Chromatin helps condense DNA strands to smaller units that can be easily managed during DNA replication and gene expression. This also prevents the breakage of the strands and facilitates equal distribution of chromosomes during cell division (during mitosis and meiosis).
Distal Convoluted Tubule and Collecting Duct are parts of the nephron does ADH act on to regulate water reabsorption. ADH acts throughs G-protein coupled receptor in order to increase transcription and the insertion of Aquaporin–2 channels for the apical membrane of the CD and DCT cells. Therefore, the permeability of CD and DCT cells to the water increases.
A Distal Convoluted Tubule (DCT) is a short nephron segment, a portion of kidney nephron between Henle or macula densa and the collecting tubule loop. It plays an important role in regulating extracellular fluid volume and electrolyte homeostasis. In DCT, Sodium absorption occurs, which is mediated by the hormone aldosterone.
