Explanation:
Before mitosis, the chromosomes are copied. They then coil up, and each chromosome looks like a letter X in the nucleus of the cell. The chromosomes now consist of two sister chromatids. Mitosis separates these chromatids, so that each new cell has a copy of every chromosome
Answer:
N≡N bond
Explanation:
Bond energy (bond enthalpy) is a measure of the bond strength in the bond. It is defined as average value of bond dissociation energies in the gas-phase for all the bonds having same type with in same chemical species.
<u>The greater the bond energy, the greater is the amount of energy required to break the bond, the more stable is the bond.</u>
Thus, among the following bonds:
O=O 498 kJ/mol
N≡N 946 kJ/mol
C=C 614 kJ/mol
C=O 745 kJ/mol
C≡C 839 kJ/mol
<u>The greatest bond energy is of N≡N 946 kJ/mol and thats why it is the most stable.</u>
Explanation:
direction of electric field is same as that of force experienced by the test charge
Answer:
Transfer of electricity without wire , is known as wireless electricity.
Sir Nicola Tesla came up with this concept.
Answer:
As they vibrate, they pass the energy of the disturbance to the particles next to them, which pass the energy to the particles next to them, and so on. Particles of the medium don't actually travel along with the wave. Only the energy of the wave travels through the medium
