<h2>Function of Macrophages</h2>
Explanation:
- <em>Macrophages are effector cells of the</em> <em>innate immune system</em> that phagocytose microscopic organisms and emit both expert incendiary and antimicrobial middle people
- The <em>macrophages </em>assume a significant role in wiping out <em>unhealthy and harmed cells through their customized cell death </em>
- <em>Macrophages </em>are produced through the separation of <em>monocytes</em>, which transform into <em>macrophages when they leave the blood</em>
- There are two kinds of tissue macrophages such as <em>macrophages that live inside explicit organs/tissue (free macrophages and fixed macrophages) and macrophages</em> got from monocytes in response to inflammatory stimuli
The cyanobacteria changed the composition of the earth’s atmosphere by evolving oxygen in what is referred to as the Great Oxygenation Event. This also allowed the ozone to be formed and block off most of the UV rays that are destructive to genetic material. Life was, therefore, also able to exist on land other than in water.
For evolution to occur:
There must be genetic variation in a population. This provides variation on which natural selection can act. Then natural selection can act by selecting those species which are better adapted to the environmental conditions. Over time those animals that are best suited to the environment only will survive and reproduce. Those organisms successful genes will be preserved and eventually the gene frequency in the population will change, changing the overall characteristics of a population. This is how evolution occurs.
