Who replaces light bulbs on cell phone towers?
They are replaced by employees of the maintenance departments of the various corporate utility entities that are responsible for the functioning and upkeep of the towers.
Does knee replacement stop arthritis?
No the knee replacement only replaces the damaged joint however it may well have removed the affected area and the pain involved.
How does the process of upwelling affect the distribution of life in the ocean?
The water brought to the surface by upwelling tends to be richer in nutrients than the water it replaces--more nutrients, more life.
Electrons from what replaces the electrons from photosystem 2 during noncyclic electron flow?

What does the light reaction require that the dark reaction does not?
the light reaction requires energy from the sun in the form of photons. these photons excite the electrons in photosystem II and results in the electrons passing through a series of redox reactions (creating a proton gradient that through chemiosmosis turns ADP into ATP) and replaces the missing electrons of photosystem I. then when photons hit photosystem II the electrons are re-energized and go through the reaction to reach NADP+ and though NADP+ reductase are accepted by the newly formed NADPH. so in short the products of the light reaction is what is required by the dark reaction (as well as 3 CO2)

It's an intergrated circut. Hope this helped(:
Why is the mobility of electrons greater than the mobility of holes?
In an intrinsic semiconductor, a few electrons get thermally excited and break from their valence bond to become a free electron. This leaves behind a vacancy in its place called 'hole'. In a P-type semiconductor, B with 3 electrons replaces a Si atom with 4 electrons in the lattice. 3 covalent bonds are formed by B with 3 neighbouring Si. But there is a deficiency of one electron in B for bonding with the 4th Si. This deficiency/vacancy is called a hole. When an electric potential difference is present, the electrons from adjacent valence bond moves into the vacancy near it while moving along the potential. The following represents the movement of valence electron. Terminology: * represents valence electron _ represents hole A is -ve and B is +ve. ..I A * * * _ * * * B .II A * * _ * * * * B III A * _ * * * * * B .IV A _ * * * * * * B I- Hole is at the 4th position. II- At first, the 3rd electron from left shifts right to fill the vacancy and leaves behind a vacancy in its place. The vacancy is at the 3rd position. III- Next, the 2nd electron from left has shifted to the 3rd place and filled up that vacancy but leaves a vacancy at its place. The vacancy is at 2nd position. IV- Now, the 1st electron from left moves to occupy the vacancy at the 2nd position creating another vacancy in its own place. The vacancy is at 1st position. As the electrons moved right, the vacancy moved left. The vacancy is called a hole (just a shorter name for convenience). The movement of holes is really the movement of electron in the valence band. Therefore, the mobility of a hole is indirectly the mobility of valence electrons. Mobility is the velocity acquired per unit electric field. In the intrinsic and N type semiconductors, many free electrons are present i.e. electrons in conduction band which are free to move in the crystal as against valence electrons which can only move in the lattice points. When an electric field is applied, both the valence electrons and the free electrons move in the same direction. The hole direction is opposite to that of valence electron but the mobility is the same, as explained earlier. Even for the same electric field, valence electrons cannot move as freely as the free electrons because its movement is restricted. Therefore, the velocity of valence electrons is less compared to free electrons. In other words, the velocity of holes is less compared to free electrons. This means mobility is also less for a hole compared to free electron. Thus, mobility of a free-electron (often abbreviated as 'electron') is greater than that of a hole (indirectly referring to valence electron).
Where do the electrons go in the common wire?
the electrons don't actually go anywhere, they move in a circular mode... the electrons bounce from one atom to another so that there is always balance... as soon as a valence electron moves to another atom another electron replaces the one just lost...
What is the function of DPIP in this experiment?
Is this an AP lab?The DPIP replaces NADP+.In photosynthesis, NADP is reduced to NADPH, but NADP is colorless.DPIP replaces the NADP. When DPIP is reduced, it changes from blue to clear. DPIP is used to show photosynthesis taking place.
Why only 3rd and 5th group elements are used for doping of a semiconductor why not other group elements?
III and V group atoms are used for doping in column IV materials. III and V relate to the number of valence electrons that are available for bonding. Silicon, which is a column IV material, is usually in a bonding form with 4 other Si atoms. In this bonding scheme, valence electrons are shared and the "outer shell" of 8 electrons is complete. In doping, an atom replaces one of the Silicon atoms. A column V atom, such as Phosphorous, can replace a Silicon atom. The bonding will be the same, except that P will provide an extra electron to the system. With thermal energy, this electron can become disassociated with its original atom, thus ionizing the dopant and creating a free electron that can be used for conduction or other processes. In p-type doping, such as using Boron in Silicon, one of the bonds is not satisfied, since Boron only has 3 valence electrons. We call this absence of an electron a "hole". In compounds such as GaAs, we have a III-V compound. In this case, you can use a column IV material for doping. So, Silicon can be used as a dopant for a III-V compound. If Si replaces a Ga atom, then Si acts like a donor. If Si replaces a As atom, Si acts like an acceptor. People in the field can use other factors, such as pressure, to preferentially select which atoms Si will replace.

Why it is necessory to assume sp3 hybridization in CH4?
In valence bond theory it is assumed the four electron pair bonds reside tetrahedrally about the carbon giving rise to the terahedral shape of the molecule. sp3 hybridisation is "necessary", it replaces the s , px, py and pz orbitals with four orbitals of identical energy (degenerate) with lobes pointing to corners of a tetrahedron- the 4 electrons are then promoted to these orbitals - the hybridisation energy.
