When mucus, fluid or tissue becomes trapped, a cyst forms. Nabothian cysts are so common that they're considered to be a normal feature of cervical anatomy. Your doctor might discover one incidentally during a pelvic exam. In general, cervical cysts don't cause symptoms and require no treatment. Your doctor might collect a tissue sample (biopsy) to send for lab testing if a cervical cyst or other lesion looks unusual. Other red flags include abnormal vaginal bleeding, pelvic pain or pain during intercourse.
Calcareous ooze is a calcium carbonate mud formed from the hard parts (tests) of the bodies of free-floating organisms.Once this mud has been deposited, it can be converted into stone by processes of compaction, cementation, and recrystallization.owever, calcareous ooze will not accumulate in the very deepest parts of the ocean, even if the surface is teeming with the right sort of organism. The reason for this will be discussed in the next section of this article.
Protozoa ingest their food in two ways. The first is a process called phagocytosis, in which a flexible portion of the cell membrane surrounds a food particle and engulfs it, bringing it into the cell in a vacuole. Phagocytosis is used to ingest other unicellular organisms or large particles.age 1 of 2. Protozoa are the animal-like protists. These unicellular eukaryotes lack cell walls. They are heterotrophic and feed on other microorganisms or on organic particles.
