A nucleus controls all the other parts of the cell
Answer:

Explanation:
Electric field strength= Force/unit charge
E= (kQq/r²)/q ₓ r
where r is the unit vector in the direction of unit charge
E= 
The answer is A because fusion has never been controlled in a non explosive manner.
Into molecules of
sugar and
oxygen.
The complete reaction of the photosynthesis is in fact:

and the energy of the light coming from the sun is also used to make the reaction possible.
Answer:
The smallest film thickness is 117 nm.
Explanation:
Light interference on thin films can be constructive or destructive. Constructive interference is dependent on the film thickness and the refractive index of the medium.
For the first interference (surface nearest to viewer), the minimum thickness can be expressed as:

where n is the refractive index of the bubble film.
Therefore,


∴
