Answer:
Para determinar la distancia a la que se encuentra una gaviota respecto del nivel del mar, es necesario medir la altura a la que se encuentra volando. Así, dado que el nivel del mar tiene una altura considerada como de 0 metros, si la gaviota está volando a unos 500 metros de altura, por ejemplo, esa será su distancia respecto del nivel del mar.
Because the AV node takes on the role of a very important delay in the cardiac conduction system. Without this delay, the atria and ventricles would contract at the same time.
<h3>Cardiac conduction system</h3>
The conduction system of the heart sends electrical signals, usually generated by the sinus nodes, causing the heart muscle to contract. Pacemaker signals originating from the sinus node travel through the right atrium to the atrioventricular (AV) along the bundle of His and through branches of the bundle, causing myocardial contraction. This signal first stimulates contraction of the right and left atria then flows to the right and left ventricles. That electric current then allows blood to be pumped throughout the body.

DNA telomerase adds a tail to the DNA strand at the end of replication. Thus, the correct option is C.
<h3>What is DNA replication?</h3>
DNA replication may be defined as a biological process in which the genome's DNA is duplicated in cells. It is completed in three steps, i.e. initiation, elongation, and termination.
DNA telomerase is an essential enzyme in DNA replication that augments the ends by duplicating the RNA template and extending one end of the chromosome.
Therefore, the correct option for this question is C.
