Proteins are made by ribosomes and then folded into their correct shape inside the endoplasmic reticulum. These proteins are then taken to the Golgi apparatus, or body, to be modified and then placed into little sacs called vesicles to transport the proteins. The two organelles are related in how they are both involved in the assembly and transportation of proteins.
Answer:
Noble gases are the group 0 elements and are all considered as the unreactive non-metal gases. Their application relies upon their low density, inertness, and non-flammability. In comparison to other elements, the noble gases are inert, that is, they are excessively unreactive.
Generally, when the elements react, their atoms complete their outer shells by gaining, losing, or sharing electrons. The noble gases atoms already possess complete outer shells, thus, they do not possess the tendency to gain, lose, or share electrons. This is the main reason why noble gases are inert and are not involved in chemical reactions.

Which of the following is an organic growth factor? A) Glucose B) NAD+ C) Peptone D) NH4H2PO4 E) H2O
Answer: B) NAD+ is an organic growth factor.
The full form of NAD is : Nicotinamide adenine dinucleotide.
This compound consists of two nucleotides joined through their phosphate groups. NAD+ is an oxidizing agent.
