Each (both large and small) colony is carefully counted (using magnifying colony counter if needed). Each colony represents a “colony-forming unit” (CFU). For accurate counts, the optimum count should be within the range of 30-300 colonies/plate. To insure a countable plate a series of dilutions should be plated.
The factors that the nurse expects in the influence of
development of teeth in the neonates are the following;
-
Medication and illness of neonate
-
Fluoride level that is present in the supply
water
-
The medication or illness that the mother has
I believe the appropriate answer is, short amino acid chains, NAG, NAM, and some lipid proteins.
Peptidoglycan is also known as Murein, it is a polymer consisting of sugars and amino acids that form a mesh-like layer outside the plasma membrane of most bacteria, forming the cell wall. The sugar component consist of alternating residues of β-(1,4) linked N-acetylglucosamine (NAG) and N-acetylmuramic acid (NAM),
Answer:
The cells are connected by gap junctions.
Explanation:
A gathering of protein channels, which permits small molecules and ions to move between the neighboring cells is termed as a gap junction. The protein channels that form gap junctions comprise two connexons, of which one is situated in the membrane of one cell that combines and aligns with the connexon of the adjacent cell.
This association produces a spontaneous pathway, which permits the small molecules and ions to pass passively from one cell to another. The gap junctions are found in all the kinds of cells, however, they are not found in skeletal muscle, RBCs, and blood lymphocytes.
Thus, the passing of the fluorescent dye from one cell to another shows that the two cells are connected with the help of gap junctions.
