<span>Asexual
reproduction produces offspring that are genetically identical to a single
parent. The offspring may either bud from the parent or by fission. An example
of this is Baker’s yeast. They are produced by budding. So as the small bud
grows from the parent, it receives the same nucleus of the parent. When it
pinches off from the parent, it is smaller but is genetically similar to the
parent. On the other hand sexual reproduction involves two parents that contribute
to the genetic material in order to produce a unique offspring. Your answer is
incorrect. The correct answer is letter B.</span>
A voltaic cells/ Galvanic cell uses a spontaneous reaction to generate electrical energy in this type of cell, the system does work on the.
This is the spontaneous chemical reaction that produces an electrical current through an outside circuit. These cells are important because they are basic for batteries that fuel modern society. it is occurs with no outside intervention.
This is used the energy released during a spontaneous red-ox reaction to generate electricity. That reaction will have a negative value of gibb's free energy, delta- G. Electrochemical cell is often called a voltaic cell after its inventor the Italian physicist alessandro volt.
