When ice melts, heat energy is being thrown into it, and the water is no longer cold enough to hold its shape. otherwise, the energy just goes into raising other temperatures or providing another type of energy
Ans.1. False.
RNA or ribonucleic molecules are polymer of nucleotide molecules that perform various functions in a cell. rRNA is referred as ribosomal RNA and are involved in synthesis of ribosomes along with proteins. Ribosomes are described as molecular factory for protein synthesis, hence, rRNA plays an important role in protein synthesis.
Thus, given statement is false.
Ans.2.
Transcription is defined as a process, by which a parental DNA molecule gets transcribed into a RNA molecule with the help of RNA polymerase enzyme. The RNA molecule is then, translated into a specific polypeptide chain or protein.
According to central dogma of molecular biology, genetic information flows from a DNA molecule to a protein. During this, first step includes transcription (formation of RNA from DNA) and second step includes translation (formation of protein form RNA).
Thus, transcription plays an important role in the central dogma of molecular biology.
Answer:
To control what entertainment and leaves
Explanation:
The cell membrane act as a selectively permalink membrane to substances entering and leaving the cell
It is a Chemical reaction taking place un a solution in which one or more of the products is insoluble in the solvent, and so forms solid particles that fall to the bottom of the reactor
