In cell culture biology, confluence is the term commonly used as an estimate of the number of adherent cells in a culture dish or a flask, referring to the proportion of the surface which is covered by cells.or example, 50 percent confluence means roughly half of the surface is covered and there is still room for cells to grow. 100 percent confluence means the surface is completely covered by the cells, and no more room is left for the cells to grow as a monolayer.
One of the few external rigid points on the GZ-20âs envelope, it holds the battens, attachments for the nose lines and the mooring spindle. 2. Material. The largest component of the Blimp, the GZ-20âs envelope is made of two-ply, neoprene-impregnated polyester fabric. 3. Ballonet. Located in the forward and aft of the envelope, these air bags allow the pilot to regulate the amount of helium in the Blimp and statically trim the ship in a nose-up or nose-down situation.
Rating Newest Oldest. Best Answer: The muscles are made up of packages of stretchable fibre like material. Every fibre of the muscle is approximately forty millimeter in length and is made up of a number of very small strands which are known as fibrils. These fibres are extremely slender, so much so that one square centimeter of a muscle contains in it up to one million fibres. Each fibre is commanded by a nerve which makes it to contract. The number of fibres, contracting, determine the strength of muscles work. Muscle is mainly composed of muscle cells. Within the cells are myofibrils; myofibrils contain sarcomeres, which are composed of actin and myosin.
