Answer;
-Matrix
Explanation;
Matrix is used to maintain artificial wall around the tooth preparation.
Cavity preparation is the mechanical alteration of a tooth to receive a restorative material which will return the tooth and area to proper form, function and esthetics.
-Objectives of cavity Preparation: remove all defects and give the necessary protection to the pulp, locate the margins of the restoration as conservatively, form the cavity so that under the forces of mastication the tooth or the restoration will not be displaced and also Allow for the esthetic and functional placement of a restorative material.
Answer:
It should be noted the options for the question are not complete. But the answer is,
As capillaries become engorged, the upper respiratory tract is affected by the subsequent edema and hyperemia, which causes these conditions, seen commonly during pregnancy.
Explanation:
Nasal congestion is a situation where the nasal passage become blocked. This is due to the swollen of the tiny blood vessel lining the nose. This is because the blood vessels have been inflamed.
There are many methods which can be adopted to relieve it.Some of them are
* Drinking lots of fluid
* Breathe in steam from a container with warm water
* using vaporizer
* Avoiding chlorinated pools.
Epistaxis is known to be bleeding from the nose. This can be caused by been exposed to dry air, which can cause the damage of the tiny blood vessels.
One of the methods that can be use as treatment is cauterization. This is the use of chemical swabs to cautirize the nose , and this eventually seals the damaged blood vessels.
This is an emergency situation in a pregnant woman because, it may may reduce the amount of oxygen required by the unborn baby.
When a skeletal muscle fiber is at rest, its ATP demands are met by ADP and creatine phosphate. In a resting muscle, excess ATP transfers its energy to creatine, producing ADP and creatine phosphate. This acts an energy reserve that can be used to quickly create more ATP. When the muscle starts to contract and needs energy, creatine phosphate transfers its phosphate back to ADP to form ATP and creatine.
Answer:
may increase the rate of mitosis in human cells
Explanation:
As you can see from the question above, the stained chromosomes of rapidly dividing cells contain numerous dark and dotted structures; on the other hand, older human cell chromosomes that have stopped dividing have very few, if any, similar structures. to points. From this we can imagine that these dark dotted structures may have some influence on the rate of cell mitosis. Of course some research must be done to prove this, but if we are to generalize what these structures can cause, we can say that they may increase the rate of mitosis in human cells
.
