tino4ka555 [31]

The differences between the geomagnetism and electromagnetism are given below.

<h3><u>Explanation</u>:</h3>

Geomagnetism is defined as the magnetic field that is located all around the earth. Whereas electromagnetism is defined as the magnetic field that is produced due to passing of electricity through a conductor.

The geomagnetism is formed because of the molten elements of iron etc which are present inside Earth's core, and are continuously moving. It mostly resembles the solid block magnet in its field characteristics. But electromagnetism is different. It can be changed according to the current input which isn't possible for Earth’s magnetic field.

LekaFEV [45]

Answer:

Opportunistic, endogenous pathogen

Explanation:

Opportunistic infection is an infection that is caused by the microbes that are otherwise the component of one's own normal microbiota.  Under particular conditions, the microbes become pathogenic and cause infection. The pathogen-derived from one's own microbiota is called endogenous pathogen.

According to the given information, <em>Candida albicans </em>is a part of the microflora of mouth but becomes pathogenic under certain conditions. In healthy individuals, they do not produce disease as their overgrowth is suppressed by other microbiota and other host resistance mechanisms. The infection occurs only in those individuals with predisposing factors such as weakened immune system or after consumption of antibacterial medications that disturb the normal microbiota and immune competency. This makes it an opportunistic, endogenous pathogen.
