The sarcolemmas from adjacent cells bind together at the intercalated discs. The answer is Intercalated discs, this join cardiocytes end to end. Complex structure with three features NOT found in skeletal muscle. Which helps support the synchronized contraction of the muscle.

Answer:

Intercalated discs

Explanation:

Intercalated discs are thickening of the plasma membrane of cardiac muscle cells and are formed when these cells are attached end to end. Intercalated discs have desmosomes and gap junctions. Desmosomes serves to hold the cardiac muscle fiber together during contraction of cardiac muscles and impart strength. Function of gap junctions is to serve as path for immediate conduction of electric signal to ensure synchronized contraction of cardiac muscle cells.

Lynna [10]

Answer:

Malignant melanoma cells would have active telomerases that constantly replenish and lengthen telomeres.

Explanation:

Telomerase can be described as enzymes which add the repetitive sequences called telomeres at the end of a chromosome. Telomeres can be described as repetitive sequences at the end of the chromosome which are involved in protecting the chromosome from any damage.

In a normal skin cell, the telomeres will shorten with time. But in a malignant skin cell, the telomerase will add the repetitive sequence again and again. The telomers will not be able to shorten.
