Answer:
Translation
Explanation:
Translation is the process by which mRNA is decoded and translated to produce a polypeptide sequence, otherwise known as a protein. This method of synthesizing proteins is directed by the mRNA and accomplished with the help of a ribosome, a large complex of ribosomal RNAs (rRNAs) and proteins. In translation, a cell decodes the mRNA’s genetic message and assembles the brand-new polypeptide chain. Transfer RNA, or tRNA, translates the sequence of codons on the mRNA strand. The main function of tRNA is to transfer a free amino acid from the cytoplasm to a ribosome, where it is attached to the growing polypeptide chain. tRNAs continue to add amino acids to the growing end of the polypeptide chain until they reach a stop codon on the mRNA. The ribosome then releases the completed protein into the cell.

Answer:
Responding to the environment
Explanation:
Sweating and panting are mechanisms of homeostasis i.e the regulation of the body's internal environment in response to changes or fluctuations in the external environment.
Sweating is a physiological response to the body's core temperature rising above the limit of 36.5-37.5°C. Once the hypothalamus in the brain detects this rise in temperature, cooling mechanisms are initiated. One of these is sweating. Release and subsequent evaporation of sweat through the sweat glands produces a cooling effect.
Panting is a physiological response more observed in dogs. Dogs lack sweat glands and therefore cannot lower their core temperature through sweating. Panting utilizes saliva instead of sweat to lower body's temperature to the set limit.
Answer:
Gene. A segment of a DNA molecule (a sequence of bases) that codes for a particular protein and determines the traits (phenotype) of the individual. A gene is the basic unit of heredity in a living organism.
