Fannia pellucida is a species of fly in the family Fanniidae. [1] [2] [3]
In mammals, pregnancy is the period of reproduction during which a female carries one or more live offspring from implantation in the uterus through gestation. It begins when a fertilized zygote implants in the female's uterus, and ends once it leaves the uterus.
Peperomia is one of the two large genera of the family Piperaceae. It is estimated that there are at least over 1,000 species, occurring in all tropical and subtropical regions of the world. They are concentrated in South and Central America, but may also be found in southern North America, the Caribbean islands, Africa, Oceania, and southern and eastern parts of Asia. The exact number of species is difficult to determine, as some plants have been recorded several times with different names, and new species continue to be discovered. Peperomias have adapted to many different environments and their appearances vary greatly. Some are epiphytes or lithophytes, and many are xerophytes or possess underground tubers (geophytes). Most species are compact perennial shrubs or vines.
For fertilization to happen between a sperm and egg cell, a sperm must first fuse with the plasma membrane and then penetrate the female egg cell to fertilize it. While the fusion of the sperm cell with the egg cell's plasma membrane is relatively straightforward, penetrating the egg's protective layers, such as the zona pellucida, presents a significant challenge. Therefore, sperm cells go through a process known as the acrosome reaction, which is the reaction that occurs in the acrosome of the sperm as it approaches the egg.
The zona pellucida is the specialized area surrounding mammalian oocytes (eggs). It is also known as an egg coat. The zona pellucida is essential for oocyte growth and fertilization.
Crassula is a genus of succulent plants containing about 200 accepted species, including the popular jade plant. They are members of the stonecrop family (Crassulaceae) and are native to many parts of the globe, but cultivated varieties originate almost exclusively from species from the Eastern Cape of South Africa.
Human fertilization is the union of an egg and sperm, occurring primarily in the ampulla of the fallopian tube. The result of this union leads to the production of a fertilized egg called a zygote, initiating embryonic development. Scientists discovered the dynamics of human fertilization in the 19th century.
The Fanniidae are a small group of true flies largely confined to the Holarctic and temperate Neotropical realms; there are 11 Afrotropical species, 29 Oriental, and 14 Australasian.
The lesser house fly, commonly known as little house fly, is a species of fly. It is somewhat smaller than the common housefly and is best known for its habit of entering buildings and flying in jagged patterns in the middle of a room. It is slender, and the median vein in the wing is straight. Larvae feed on all manner of decaying organic matter, including carrion.
Zona pellucida sperm-binding protein 3, also known as zona pellucida glycoprotein 3 (Zp-3) or the sperm receptor, is a ZP module-containing protein that in humans is encoded by the ZP3 gene. ZP3 is the glycoprotein in the zona pellucida most important for inducting the acrosome reaction of sperm cells at the beginning of fertilization.
The eastern sand darter is a species of freshwater ray-finned fish, a darter from the subfamily Etheostomatinae, part of the family Percidae, which also contains the perches, ruffes and pikeperches. The eastern sand darter is a relatively small fish, most plentiful in the Mississippi and Ohio Rivers, as well as Lake Champlain and the Great Lakes. It prefers sandy-bottomed streams and sandy shoals in the lakes. The eastern sand darter feeds on larvae of black flies and other small insects in the water. They also feed on zooplankton in small portions since their small mouth size limits their gape ability. Its average body size is around 1.5-2 in long, and it breeds in the spring and summer in sandy-bottomed waters.
Tetraphidaceae is a family of mosses. It includes only the two genera Tetraphis and Tetrodontium, each with two species. The defining feature of the family is the 4-toothed peristome.
Zona pellucida sperm-binding protein 4, ZP-4 or avilesine, named after its discoverer Manuel Avilés Sánchez is a protein that in humans is encoded by the ZP4 gene.
Fannia is a very large genus of approximately 288 species of flies. The genus was originally described by the French entomologist Jean-Baptiste Robineau-Desvoidy in 1830. A number of species were formerly placed in the genus Musca.
Eviota pellucida, commonly called neon pygmy goby or pellucida pygmy goby, is a species of marine fish in the family Gobiidae.
Carronella pellucida is a species of sea slug, an aeolid nudibranch, a marine heterobranch mollusc in the family Flabellinidae. It is occasionally referred to as the milky white sea slug, the pellucid aeolid, or the red-gilled nudibranch, though these names are not commonly accepted in formal settings.
Neottiura bimaculata is a species of cobweb spider in the family Theridiidae. It is found in North America, Europe, Turkey, Caucasus, Russia (Siberia), Central Asia, China, and Japan.
Toxophora pellucida is a species of bee fly in the family Bombyliidae.
Physonota is a genus of tortoise beetles and hispines in the family Chrysomelidae. There are more than 40 described species in Physonota.
Geminaria pellucida is a species of bee flies in the family Bombyliidae.
Camnula is a genus of band-winged grasshopper in the family Acrididae. It contains one species, Camnula pellucida, the clearwinged grasshopper. This grasshopper is found in most of North America excluding some southeastern states. It can be a severe pest in grains and rangelands.
