Covalent bonds consist of pairs of electrons shared by two atoms, and bind the atoms in a fixed orientation.
Explanation:
Electric conductors are the substances which allow easy passage of electric charges from one atom to another in the presence of a certain amount of voltage.
A conductor in which electric charge passes easily is known as a good conductor. Whereas a conductor in which electric charge passes with difficulty or no electric charge passes through is known as bad conductor.
For example, copper is good conductor of heat and electricity as it conducts flow of current quite easily.
Answer:
The electronic structures of pentacene/MoO3/Al and pentacene/Al were studied using in situ photoemission spectroscopy. The secondary electron cutoffs, highest occupied molecular orbitals (HOMOs) and core level changes were measured upon deposition of the pentacene and MoO3 to study the electronic structures at the interface.
Hope it helps!

Answer:
Embryonic stem cells are pluripotent, meaning they can give rise to every cell type in the fully formed body, but not the placenta and umbilical cord. ... Human embryonic stem cells have been derived primarily from blastocysts created by in vitro fertilization (IVF) for assisted reproduction that were no longer needed
