Can retainers still fit w a small gap?

Retainers have been designed to be used as an end of treatment to help retain your teeth in their new position. ... These are removable and fixed retainers. The reason why retainers can't be used to close a gap is because they are fitted at the end of treatment and are made to fit the straight teeth mould.

yes

Step-by-step explanation:

A, B, C, and D.

Explanation:

The reaction given is reversible, so it's an equilibrium between the left and the right reaction. At some point the velocities of them will be equal, thus statement 1 (or A) is correct.

In the lungs, the oxygen is absorbed and is joined to hemoglobin to be transported, so the reaction proceeds to the formation of HbO2, or for the right, and then statement 2 (or B) is correct.

In the muscles, the oxygen must leave the hemoglobin and then goes to the cells, so the reaction must proceed to the left and the statement 3 (or C) is correct.

The K value is the equilibrium constant for a reversible reaction, which is the multiplication of the concentration of the products elevated by their coefficients divided by the multiplication of the concentration of the reactants multiplied by their coefficients. In this case, K = [HbO2]/([Hb]*[O2]). [O2] must be high, so K has a small value, and statement 4 (or D) is correct.
