doctors would first extract cells from one of the females to create a gamete of the opposite sex (i.e. sperm). After this occurs, doctors then merge this sperm with a typically created gamete (the other woman’s egg), which then creates an embryo. ...

Consider this scenario: America sends a daring young astronaut, the cream of the crop of military pilots (immortalized in the book and movie entitled ‘The Right Stuff’), the best among the best, in a space ship to outer space at a cost of billions of dollars in today’s money; agains...
with α-lactalbumin, a mammary-specific protein, to form lactose synthase. In addition to a biosynthetic role, the protein translated from the longer transcript appears on the plasma membranes of some cells where it serves as a signalling receptor in cell-matrix interactions such as sperm-egg bin...
"It is a well-documented fact that guys will not ask for directions. This is a biological thing. This is why it takes several million guy sperm cells, each one wriggling in its own direction, totally confident it knows where it is going, to locate a female egg, despite the fact that ...
116 Working with the assumption that egg and pollen cells each carried only one set of character-determining factors, which were joined in fertilization, he noted that in offspring the separation of factors occurred randomly so that the rules could only be determined statistically for a population ...
The order name Isoptera originates from the fact that the imago (adult) has wings of equal size (Isos in Greek meaning the same and ptera meaning wings). The insects of Isoptera are commonly called termites in English. Due to their poor abdominal sclerotization and white appearance, ...
Involved in platelet activation and aggregation. Regulates paranodal junction formation. Involved in cell adhesion, cell motility and tumor metastasis. Required for sperm-egg fusion. {ECO:0000269|PubMed:14575715, ECO:0000269|PubMed:7511626, ECO:0000269|PubMed:8478605}. ...
The field that studies the nervous system is called neuroscience, and the people who study it are neuroscientists. The human nervous system is made up of billions of interconnected cells, and it is likely the most intricately organized aggregate of matter on planet Earth (Camp- bell, Reece, &...
MFGs are milk particles having a lipid-protein membrane surrounding milk fat; secreted by milk producing cells; a source of multiple bioactive compounds, such as phospholipids, glycolipids, glycoproteins, and carbohydrates. The milk fat globule is surrounded by a phospholipid trilayer containing ...
