Answer : The correct option is 'X' (mitochondria).
Explanation :
In the given animal cell diagram,
W represent the vacuole.
X represent the mitochondria.
Y represent the nucleolus.
Z represent the cytoplasm.
The function of vacuole, it stores waste products and balance the pH level of the cell.
The function of mitochondria, most of the respiration reaction occurs in which carbon dioxide is produced by utilizing oxygen.
The function of nucleolus, it contains the hereditary information.
The function of cytoplasm, most of the chemical reaction occurs.
Therefore, the correct answer is 'X' (mitochondria).
Answer:
B.) An atom of arsenic has one more valence electron and more electron shells than an atom of silicon, so the conductivity decreases because the arsenic atom loses the electron.
Explanation:
Silicon is located in the 3rd row and 14th column in the periodic table. Arsenic is located in the 4th row and 15th column in the periodic table. This means that arsenic has one more valence electron than silicon. Since arsenic is located one row down from silicon, its valence electrons occupy higher energy orbitals.
Silicon maintains a crystal-like lattice structure. Each silicon atom is covalently connected to assume this shape. When silicon gains one extra electron from arsenic, it experiences n-type doping. This new electron is not tightly bound in the lattice structure. This allows it to move more freely and conduct more electricity. This can also be explained using band gaps. Silicon, which previously had an empty conduction band, now has one electron in this band. This lowers the band gap between the conduction and valence bands and increases conductivity.
