"Amelanotic" Natural Recordings by Native Speakers
Amelanotic refers to the absence or lack of melanin, which is a pigment responsible for giving color to skin, hair, and eyes. It can be used to describe conditions where melanin production is reduced or absent, leading to pale or colorless areas.
1. The amelanotic variant of melanoma is characterized by a lack of pigmentation, making it more difficult to detect visually.
2. Researchers have discovered a new species of fish with amelanotic scales, giving it a unique transparent appearance.
3. In some cases, albinism results from a genetic mutation that prevents the production of melanin, leading to an amelanotic phenotype.
4. The amelanotic feather pattern in certain birds is a rare and striking sight, often attracting attention from birdwatchers and photographers.
5. An amelanotic mole, though typically benign, should be monitored closely as it might not change color with sun exposure and could potentially develop into skin cancer.
Amebelodon is an extinct genus of proboscidean, which means it was a prehistoric elephant-like mammal. These animals lived during the Miocene and Pliocene epochs, around 23 to 5 million years ago. They were characterized by their unusual teeth: long, tusk-like upper incisors and shorter, shovel-shaped lower teeth, which they likely used for digging and feeding on vegetation.
Amebiasis is a parasitic infection caused by the protozoan parasite Entamoeba histolytica. It primarily affects the intestines, but can also spread to other parts of the body, leading to symptoms such as diarrhea, abdominal pain, and liver abscesses. The infection is typically contracted through ingestion of contaminated food or water or through direct contact with infected fecal matter. Treatment involves the use of antiparasitic medications.
amebic refers to relating to or caused by amoebas, which are single-celled organisms that can cause disease in humans and other animals.
Amebicide is a noun that refers to a substance or medication used to kill or eliminate amebas, which are single-celled organisms that can cause parasitic infections in humans, such as amoebic dysentery or amoebic liver abscess.
Amebocytes are cells found in the hemolymph (the equivalent of blood in invertebrates) of certain invertebrates, such as mollusks and echinoderms. These cells have a variety of functions, including phagocytosis (engulfing and digesting foreign particles or pathogens), transportation of nutrients, and participating in immune responses. In some cases, amebocytes can differentiate into other cell types when needed, contributing to tissue repair or defense mechanisms.
Ameboid refers to something that resembles or has the movement of an ameba, a single-celled organism that changes shape and moves by extending pseudopodia (false feet). It can also describe cells or organisms with a similar ameboid motion or shape.
Ameiuridae is a family of small, freshwater crustaceans commonly known as amphipods. They are part of the order Amphipoda and are typically found in various aquatic habitats such as rivers, lakes, and wetlands. These crustaceans have a shrimp-like appearance and are known for their ability to swim and burrow in sediment. They play an important role in aquatic ecosystems as both prey and decomposers.
"Amelanchier" is a genus of flowering plants in the rose family, commonly known as serviceberries or shadbushes. They are deciduous shrubs or small trees that produce white or pink flowers in spring and edible, berry-like fruits in summer. The name "Amelanchier" is derived from the old French word "amelein," which refers to a type of bird that was believed to feed on the berries.
