Atomic number od iodine is 53. That number show number of protons (in neutral atom number of electrons and protons are the same). So number of electrons are 53 and number of protons are 53.
Mass number of this isotope of iodine is 131. That number show number of neutrons +number of protons. So, number of neutrons:131-53=78.
It would be C!
Only plants have chloroplast, they use it in the process of photosynthesis. The cell membrane is found in both plant and animal cells, though! It works to regulate whatever comes inside the cell, and it also assists in holding the cell's shape.
<span>asymmetric centers are present in the open chain form of the Aldohexose d-(-)-Gulose.Explanation:
Here the word Asymmetric center
means those carbon atoms which contains atoms or group of atoms different from each other. All the four atoms or group of atoms
attached to carbon atom are different and have different molecular masses. Such carbon atoms are also called as Chiral carbons
. The structure of </span>d-(-)-Gulose is drawn below, and all Four Asymmetric centers are pointed by " *
