For question number two, it's the second statement that doesn't describe the structure of an atom.
Answer:
J) Providing information to form proteins
Explanation:
Messenger RNA (mRNA) is the molecule that links genes to proteins. Efficient and smooth interactions of the molecules of life allow us humans to function well. ... This process is called gene expression.
Answer:
the forces between the two charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them
Answer:
NAD is a coenzyme found in all cells. It consists of two nucleotides linked through their phosphate groups with a nucleotide that contains an adenosine ring and another that contains nicotinamide.
Explanation:
In metabolism, NAD participates in oxidation reduction reactions. This coenzyme is found in two forms in the cells: NAD and NADH. NAD accepts electrons from other molecules and is reduced, forming NADH, which you can use as a reducing agent to donate electrons. These electron transfer reactions are the main function of the NAD.
In living organisms, NAD can be synthesized from scratch from the amino acids tryptophan or aspartic acid. Some NADs are found in nicotinamide adenine dinucleotide phosphate (NADP), whose chemistry is similar to NAD, although it has different functions in metabolism.
C . the square of the distance the separated them
