After taking their wedding vows, a bride and groom often ceremonially use which of the following muscles before walking away from the altar? A) Depressor anguli oris
B) Orbicularis oris
C) Levator labii superioris
D) Platysma
E) Quadriceps femoris

B

Explanation:

The correct answer would be option B.

Orbicular oris is a muscle that runs around the outside of the mouth. It is the muscle responsible for changing the shape of the mouth during different actions such as talking, whistling, and kissing.

Depending on the intensity of the kiss though, some other muscles in the body might get involved as a result of other actions such as the movement of the head, the wagging of the tongue, etc. However, the primary muscle during kissing remains the orbicularis oris muscle.

Hence, the correct option is B.

when a reversible reaction is occurring in both directions at the same rate; the products and reactants do not change in concentration. a chemical reaction where the compound is broken into its constituent parts.

the transfer for conduction is the heat transfering from the liquid to the spoon

the transfer for radiation is the heat going through the sides of the cup and to the air

at least that is what i would do
