Answer:
Neighboring cardiac muscle cells in the walls of heart chambers have specialized cell-to-cell contacts that electrically and mechanically link the cells together, permitting the immediate passage of muscle impulses. These cell-to-cell contacts are called <u>intercalated discs.</u>
Explanation:
Intercalated discs can be described as unique structures present between the cardiac muscles of the heart. The intercalated discs play a major role in making the cardiac muscles contract in a rhythm so that the heart can pump blood in a regular fashion and it hence regulates the effective functioning of the heart. The intercalated discs are the structures that join on cardiac muscle to another and is involved in the transmission of chemical messages between them.
<u>Answer:</u>
<em>B) it requires only transfer RNA (tRNA) and ribosomes.</em>
<u>Explanation:</u>
After the <em>transcription of DNA to RNA</em> in nucleus of cell, the ribosomes synthesis protein and this process is known as the Translation. <em>For the translation process to occur, it requires transfer RNA (tRNA) and ribosomes.</em>
The translation process is also known as cell expression. The ribosomes help in translation by inducing <em>transfer of tRNA sequence of anticodon to codon of mRNA.</em>
