Individuals can take a course of antibiotics to their immune system fight bacterial diseases. which of the following best explains why these antibiotics may lose their effectiveness against certain bacteria? a.) antibiotics have become diluted and weak because of a limited supply.
b.) resistant bacteria are polyploidy and can resist the antibiotic, a trait that is passed on to their offspring.
c.)some bacteria have randomly mutated to resist the antibiotic, and this resistance is inherited.
d.) bacteria have purposefully directed their immune system to resist the effect of the antibiotic.

C.)Some bacteria have randomly mutated to resist the antibiotic, and this resistance is inherited.

Explanation:

Antibiotics is used to describe any substance that helps combat disease-causing microbes especially bacteria by killing their cells. This antibiotic is taken in as drugs to boost or help the immune system in the fighting process against bacterial infections. However, some bacterial species seem unresponsive to these antibiotics. This phenomenon is called antibiotic-resistance.

Changes may occur in the genetic sequence of bacteria that leads to antibiotic-resistance. These changes called MUTATION can be one that adds specific nucleotides to the genetic sequence of the bacteria, hereby, conferring resistance to certain antibiotics upon it.

Since the change (mutation) emanates from the gene of the bacteria, this specific resistant abilities will be transferred to their offsprings when they reproduce. This will cause an increased number of antibiotic-resistant strains of bacteria, posing further problems.

interphase

the period of cell growth when the cell synthesizes new molecules and organelles. the cell is not dividing and it constitutes the majority of the time spent in the cell cycle

prophase

changes occur in the nucleus and cytoplasm. the chromatin condenses to form structures (sister chromatids) visible with a light microscope and the mitotic spindle begins to form, but the nucleus is still in tact

prometaphase

the nuclear envelope fragments and the spindle microtubules attach to the kinetochores of the sister chromatids

metaphase

all the cell's duplicated chromosomes are lined up at an imaginary plane equidistant between the poles of the mitotic spindle

anaphase

begins when sister chromatids separate from each other and ending when a complete set of daughter chromosomes arrives at each of the two poles of the cell

telophase

the daughter nuclei form at the two poles of a cell

cytokinesis

the division of a cytoplasm to form two separate daughter cells. usually occurs during telophase during mitosis. this and mitosis make up to mitotic (m) phase of the cell cycle
