macrophage are immune system cells that patrol the blood and body tissues. when a macrophage finds a foreign invader, the macrophage ingests (takes in) the foreign invader and then chemically digests (breaks down) that foreign invader. to perform this frequent chemical digestion, macrophage have more than the average body cell is

Macrophages are immune system cells that are vital to the development of non-specific defense mechanisms that provide the first line of defense against pathogens. These large immune cells are present in nearly all tissues and actively remove dead and damaged cells, bacteria, cancerous cells, and cellular debris from the body.

What is Macrophages?

Macrophages are specialized cells that hunt for, engulf, and kill bacteria and other dangerous organisms. They can also activate other cells by releasing substances known as cytokines, which present antigens to T cells and start an inflammatory response.

Blood monocytes that leave the bloodstream to differentiate in various organs give rise to macrophages. Each macrophage population exhibits significant variety, which most likely reflects the level of specialization necessary for each tissue's environment.

<u>Some of the minerals necessary for the formation of chlorophyll include magnesium, nitrogen, and iron</u>. It thus means that the humus supplied to the soil of group 1 plant has the necessary minerals to synthesize chlorophyll while the soil of group 2 plants is deficient in some or all the minerals required for chlorophyll synthesis.

The Ring of Fire is a region of tectonic activity. This means that it is an area where __________ are especially common.
Andreas93 [3]
<h2>Answer:</h2>

<u>a. Earth quakes</u> are common.

<h2>Explanation:</h2>

"Ring of Fire" is a significant region in the bowl of Pacific Ocean where numerous earthquakes and volcanic ejections happen. In an enormous 40,000 km horseshoe shape, it is related to an about nonstop arrangement of maritime channels, volcanic circular segments, and volcanic belts and plate developments. It has 452 volcanoes.

About 90% of the world's tremors and about 81% of the world's biggest seismic tremors happen along the "Ring of Fire". The Ring of Fire is an immediate aftereffect of plate tectonics: the development and impacts of lithospheric plates, particularly subduction in the northern segment.
