The correct answer is biological.

When any pathogen invades the body, it has to pass several line of defence. The first barrier is skin and mucous membrane which is a physical and chemical barrier. The second line of defence is non specific response by macrophages, neutrophills and interferon. After crossing these two barriers the third line of defence comes into action in which, the B- cells and T-cells acts specifically on the pathogen and destroys it.

Eukaryotic cells rely on the molecular energy of ATP to sustain all of the reactions necessary to maintain life, in the absence of ATP, these reactions would come to a halt, and the cell would inevitably die.

ATP is a molecular compound that provides the energy needed by most cells to survive. ATP represents Adenosine triphosphate, which is an organic compound that provides energy to drive the essential metabolic reactions of living cells, such as:

  • Muscle contractions
  • Nerve impulses
  • Chemical synthesis
  • Nutrient absorbtion

In the situation in which a cell was to run out of ATP, these reactions would stop, given that they require ATP to function. This means that the cell would not be able to send or receive nerve signals, absorb the nutrients it needs, or even create necessary compounds such as proteins. The stoppage of these functions would lead to the death of the cell.

Mitosis and cell cycle definition
Korolek [52]

Answer:Una célula pasa por cuatro etapas a lo largo de su vida, que son: el nacimiento, el crecimiento, la diferenciación y la reproducción o muerte celular.

El proceso por el cual nace una célula a partir de otra preexistente se denomina división celular. El mecanismo que da origen a un nuevo individuo, en organismos unicelulares, es decir, organismos formados por una sola célula, se produce para aumentar el tamaño de su población, mientras que en organismos pluricelulares, este proceso funciona para aumentar el número de células y el reemplazo de células que se encuentren dañadas o muertas.

El ciclo celular se define como el conjunto de transformaciones que sufren las células para generar dos células hijas.

Este ciclo está formado por tres fases: la interfase, la mitosis y la ciclo
