Answer:
Melanin will not be produced and this will result in albinism.
Explanation:
Albinism can be described as a condition which arises when there is little or no melanin production in an individual's body. It is considered to be an inherited disorder. This kind of disorder mostly occurs when mutations terminate the working of the enzyme tyrosinase. This enzyme is involved in the synthesis of melanin from the amino acid tyrosine. Hence, the termination of this enzyme will lead to the termination of melanin production.

A cardiac muscle cell contracts spontaneously and is joined to other cardiac muscle cells by structures called intercalated discs.
Explanation:
Cardiomyocytes, the only ones responsible for the contractile function of the myocardium, are terminally differentiated cells that cease to proliferate almost immediately after birth. Cardiomyocytes are mononucleated cells, with the nucleus in a central position. These are linked together by the so-called intercalary discs, which appear as dark bands in histological preparations, and which are a set of junction complexes where desmosomes and adherent junctions can be found (here called fascia adherens). The intercalary discs are therefore the boundaries between cells.
