A70-year-old male presents with back pain, fever, and weight loss. he reports that he had a recent respiratory infection from which he thought he recovered. tests revealed increased white blood cell count, and a diagnosis of endogenous osteomyelitis was made. the primary organism causing this condition is: a. staphylococcus aureusb. salmonella
c. mycobacterium
d. haemophilus influenza

The answer is C. Mycobacterium.

Explanation:

According to the symptoms the male demonstrates in the question, the primary organism causing these should be Mycobacterium because it is a bacteria that is associated with causing diseases such as Tuberculosis and Leprosy.

The symptoms of Tuberculosis include most of the listed ones which are fever, weakness and weight loss.

The diagnosis of endogenous osteomyelitis also indicates that the back pain is caused by the tuberculosis as well, Tuberculous Osteomyelitis to be exact which is also defined as Skeletal Tuberculosis.

I hope this answer helps.

prophase: we can observe the chromosomes to coil up and condense. they become visible. nuclear membrane and envelope disintigrate.s

metaphase: chromosomes align at the center, the metaphase plate. spindle fibers attach to centromeres of the sister chromatids. they meet at kinetochores.

anaphase: sister chromatids are pulled towards each opposing centromere, set on different poles.

telophase: chromosomes are now clustered up only on either sides of the cell. nuclear membranes reform, and a new cell wall forms along the cell plate. this will lead to cytokinesis, the process that divides the cell membrane and forms the cell wall.

a- all cells come from pre-existing cells
