Microorganisms can be divided into two groups:
1. Archea
• Archea are prokaryotic unicellular organisms without cell nucleus or other membrane bound-organelles.
• Their membrane is built from ether lipids, which differs them from bacteria’s cell membrane.
•
2. Bacteria
• Bacteria are also unicellular prokaryotic organisms.
• Bacterial cell membranes are made from phosphoglycerides with ester bonds. Bacterial genome is in a form of circular chromosome.
• They reproduce by binary fission or by budding.
Besides, prokaryotes (Archea and Bacteria) a large number of eukaryotes are also microorganisms. Unicellular eukaryotes contain organelles such as the cell nucleus, the Golgi apparatus and mitochondria. Usually, they reproduce asexually by mitosis. An example of eukaryotic microorganism is Protist.

Generalized anxiety disorder is a psychiatric disorder, which means something is wrong in the brain. It is a common problem, and it is characterized by persistent or excessive worrying. There are notable gender differences in the condition. Women who had history of generalized anxiety disorder face more risk of having other disorders such as bulimia, another anxiety disorder, or depression. Studies show that generalized anxiety disorders are more common in women than in men. In short, generalized anxiety disorder is a bad news for women since they suffer the most.

Answer: Phosphorus moves in a cycle through rocks, water, soil, sediments, and organisms.
Steps of Phosphorus cycle:
<u>Rain and weathering cause rocks to release phosphate ions and other minerals.</u> This inorganic phosphate is then distributed in soils and water.
<u>Plants take up inorganic phosphate from the soil.</u> The plants may then be consumed by animals. Once in the plant or animal, the <u>phosphate is incorporated into organic molecules such as DNA. </u> <u>When the plant or animal dies, it decays, and the organic phosphate is returned to the soil.</u>
Within the soil, organic forms of phosphate can be made available to plants by bacteria that break down organic matter to inorganic forms of phosphorus. <u>This process is known as mineralisation.</u>
<u>Phosphorus in soil can end up in waterways and eventually oceans. Once there, it can be incorporated into sediments over time.</u>
