Membrane, in biology, the thin layer that forms the outer boundary of a living cell or of an internal cell compartment. The outer boundary is the plasma membrane, and the compartments enclosed by internal membranes are called organelles. Biological membranes have three primary functions: (1) they keep toxic substances out of the cell; (2) they contain receptors and channels that allow specific molecules, such as ions, nutrients, wastes, and metabolic products, that mediate cellular and extracellular activities to pass between organelles and between the cell and the outside environment; and (3) they separate vital but incompatible metabolic processes conducted within organelles.
Answer:
The proteins receive electrical signals from nerve cells.
Explanation:
Answer:
Option C.
tRNA charging, in which the tRNAs bind to amino acids initiation, in which the components necessary for translation are assembled at the ribosome.
Explanation:
During the transcription phase of protein synthesis, before an amino acid can even be incorporated into a growing polypeptide, it must first be attached to a molecule called the transfer RNA (tRNA). This process is known as tRNA charging.
After this, the charged RNA can now carry the activated amino acid to the ribosome, where the protein synthesis can now take place.
The tRNA charging process is the first stage in protein synthesis
The answer is metamorphosis
The answer would be a because the jet stream is very cold and come down to the water like a magnet sort of and keeps the top of the water cold so there for you have a cold water current on the top of the water so the answer is )A
