<span>Prokaryotic cells are simple in structure when compared to eukaryotic cells. They contain non-membranous organelles, lack a cell nucleus, and have a simplistic genome: only one circular chromosome of limited size. Therefore, prokaryotic cell division, a process known as binary fission, is fast. The chromosome is duplicated prior to division. The two copies of the chromosome attach to opposing sides of the cellular membrane. Cytokinesis, the physical separation of the cell</span>
Your answer is A. Parasitism :)

Answer:
The chemical reactants on the left produce<u><em> Adenosine triphosphate (ATP)</em></u> on the right.
Explanation:
Adenosine triphosphate (ATP) can be described as the energy molecule which is used by almost every cell of an organism's body to carry out normal functions of a cell.
Adenosine triphosphate (ATP) is an unstable molecule hence it usually occurs as ADP ( Adenine diphosphate) or AMP (adenine monophosphate). When a phosphate atom attaches to ADP, ATP is produced. The breakdown of ATP releases adenine diphosphate, phosphate along with the release of energy.
Answer:
The correct answer will be option-C
Explanation:
The rhythm of the heartbeat is controlled by the pacemaker of the heart called the sino-atrial node.
The SA node generates action potentials which trigger the contraction and relaxation of the atrium and ventricles. The membrane potential generation initiates by the depolarization of the cell membrane when the L type of Ca⁺² ions opens up and calcium ions enter the cell.
This depolarizes the cell until the potential threshold is reached which lies between the -40 and -30 mV.
Thus, Option-C is the correct answer.
