Answer:

Most of space of atom is empty and in center of atom , there is solid mass which is cause of alpha particles to come back. He gave the term nucleus to this solid mass.

Explanation:

Ernest Rutherford conducted experiment in which he took a thin gold particle film on which he passes alpha- particles. He noticed that:

  1. Most of the alpha particles get through film and can be detected by detector.  
  2. Around small portion of the alpha particle deflected at small angles.  
  3. A very very few alpha particle (approximately 1 out of 1 million alpha particles) just retraced their path which means come back from the center.  

He concluded that:

<u>Most of space of atom is empty and in center of atom , there is solid mass which is cause of alpha particles to come back. He gave the term nucleus to this solid mass.</u>

This was Ernest Rutherford’s gold foil experiment. He used radioactive alpha particles as a part of the experiment and discovered that there was a densely packed, positively charged nucleus in atoms with electrons that were spread out in spaces between nuclei.

Answer:

b. reducing molecules

Explanation:

Nicotinamide adenine dinucleotide (abbreviated NAD +, and also called diphosphopyridine nucleotide and Coenzyme I), is a coenzyme found in all living cells. The compound is a dinucleotide, as it consists of two nucleotides linked through their phosphate groups with a nucleotide that contains an adenosine ring and the other that contains nicotinamide.

In metabolism, NAD + participates in redox reactions (oxidoreduction), carrying electrons from one reaction to another.

Coenzyme, therefore, is found in two forms in cells: NAD + and NADH. NAD +, which is an oxidizing agent, accepts electrons from other molecules and becomes reduced, forming NADH, which can then be used as a reducing agent to donate electrons. These electron transfer reactions are the main function of NAD +. However, it is also used in other cellular processes, especially as a substrate for enzymes that add or remove chemical groups of proteins, in post-translational modifications. Due to the importance of these functions, the enzymes involved in the metabolism of NAD + are targets for drug discovery.
