How does nuclear fission produce energy? a controlled nuclear chain reaction produces heat, driving steam turbines to produce energy. moving water turns turbines to produce electricity. carbon atoms are bombarded by small neutrons. an uncontrolled nuclear reaction produces heat, driving steam turbines to produce energy.

Option A, A controlled nuclear chain reaction produces heat, driving steam turbines to produce energy.

Explanation:

In a nuclear power plant,  the following processes takes place –

a)Series of nuclear chain fission reaction occur

b)Enormous amount of energy in the form of heat is released during each fission reaction

c)The condenser (heavy water) with in the plant absorbs this heat and converts into vapor.  

d)Water vapor or steam has high velocity which is then used to rotate the turbine connected with generator coil.  

e)Rotating coil  of generator produces electrical energy.

Hence, option A is correct

the right answer is a. skin cells forming from sunlight.

the liver is an organ endowed with a fantastic ability to regenerate

. thus, if a hepatectomy (ablation) of 70% of the hepatic mass is performed in the rat, there is complete recovery in 7 to 10 days.

prokaryotes are beings that have existed since the existence of life on earth, and do not come from another realm.

ribosomes are organelles that exist naturally in eukaryotes, either in free form or attached to the endoplasmic reticulum.
