The genes to be resistant to an antibiotic already exist in the bacteria's genes.  Those whose phenotypes are resistant to the antibiotic will survive the antibiotic which kills the other non-antibiotic-resistant bacteria.  The surviving bacteria will then asexually reproduce, producing more antibiotic-resistant bacteria.

wariber [46]

Answer:

Explanation:

En física, la materia es todo aquello que se extiende en cierta región del espacio-tiempo, que posee energía y está sujeto a cambios en el tiempo y a interacciones con aparatos de medida. Se considera que es lo que forma la parte sensible de los objetos perceptibles o detectables por medios físicos.

Etimológicamente, proviene del latín materia, que significa «sustancia de la que están hechas las cosas» y que también alude a la «madera dura del interior de un árbol»;1​ la palabra está relacionada con māter («origen, fuente, madre»)2​ y se corresponde con el griego hyle3​ (de hylos: «bosque, madera, leña, material»)4​5​ que es un concepto aristotélico de la teoría filosófica del hilemorfismo.6​

El uso moderno del término va más allá de la noción clásica de sustancia, y los físicos denominan materia a cualquier entidad cuya presencia en una cierta región del espacio-tiempo conlleva que el tensor energía-impulso para dicha región es diferente de cero.

Allushta [10]

Mitosis

Mitosis is the part of the cell cycle in which the duplicated genetic material (chromosomes) within the parent’s cell nucleus is separated to produce two daughter cells that are genetically identical to the parent. Mitosis is important to life because it is involved in the production of new cells for growth and to replace damaged cells. Mitosis occurs in five stages which are; interphase, prophase, metaphase, anaphase and telophase (cytokinesis).
