Ethel Browne Harvey
Ethel (Nicholson) Browne Harvey (December 14, 1885 in Baltimore, Maryland – September 2, 1965 in Falmouth, Massachusetts) was an American embryologist, known for her critical findings about cell division, using the embryology of sea urchins, and for early work studying embryonic cell cleavage. Biography and education Ethel Nicholson Browne was born December 14, 1885, in Baltimore, Maryland, to Bennett Barnard Browne and Jennifer Nicholson Browne. She was one of five children; three of her siblings became doctors, including two of her sisters (Jennie Nicholson Browne and Mary Nicholson Browne), and one of her brothers became a metallurgist.Donna J. Haraway, "Ethel Browne Harvey", in Barbara Sicherman and Carol Hurd Green, editors, ''Notable American Women: The Modern Period: A Biographical Dictionary.

Cell Division
Cell division is the process by which a parent cell (biology), cell divides into two daughter cells. Cell division usually occurs as part of a larger cell cycle in which the cell grows and replicates its chromosome(s) before dividing. In eukaryotes, there are two distinct types of cell division: a vegetative division (mitosis), producing daughter cells genetically identical to the parent cell, and a cell division that produces Haploidisation, haploid gametes for sexual reproduction (meiosis), reducing the number of chromosomes from two of each type in the diploid parent cell to one of each type in the daughter cells. In cell biology, mitosis (Help:IPA/English, /maɪˈtoʊsɪs/) is a part of the cell cycle, in which, replicated chromosomes are separated into two new Cell nucleus, nuclei. Cell division gives rise to genetically identical cells in which the total number of chromosomes is maintained. In general, mitosis (division of the nucleus) is preceded by the S stage of interph ...

Society For The Promotion Of University Education For Women
A society is a group of individuals involved in persistent social interaction, or a large social group sharing the same spatial or social territory, typically subject to the same political authority and dominant cultural expectations. Societies are characterized by patterns of relationships (social relations) between individuals who share a distinctive culture and institutions; a given society may be described as the sum total of such relationships among its constituent of members. In the social sciences, a larger society often exhibits stratification or dominance patterns in subgroups. Societies construct patterns of behavior by deeming certain actions or concepts as acceptable or unacceptable. These patterns of behavior within a given society are known as societal norms. Societies, and their norms, undergo gradual and perpetual changes. Insofar as it is collaborative, a society can enable its members to benefit in ways that would otherwise be difficult on an individual bas ...

Washington Square College
The New York University College of Arts & Science (CAS) is the primary liberal arts college of New York University (NYU). The school is located near Gould Plaza next to the Courant Institute of Mathematical Sciences and the Stern School of Business, adjoining Washington Square Park in Greenwich Village. As the oldest and largest college within NYU, the College of Arts & Science currently enrolls 7,660 undergraduate students (as of 2017). CAS enrolls the largest number of undergraduate students for a private liberal arts college in the United States; its size and complexity owe to NYU’s overall profile of enrolling the largest number of students in the country for a private, nonprofit, residential, and nonsectarian institution of higher education. The College of Arts & Science offers Bachelor of Arts (B.A.) and Bachelor of Science (B.S.) degrees. In the 2020 QS World University Rankings, NYU was ranked 1st in Philosophy, 10th in Mathematics, and 15th in English Language and Lite ...

History Bennett College was founded in 1890 at Irvington, New York by May F. Bennett as the Bennett School for Girls, a four-year high school with two extra years of study.Young, Michelle (June 10 2021"Inside the Abandoned Bennett School for Girls in Millbrook, NY"'' Untapped New York'' In 1907 the college moved to its final home on in Millbrook, Dutchess County, New York.

Merogony
Apicomplexans, a group of intracellular parasites, have life cycle stages that allow them to survive the wide variety of environments they are exposed to during their complex life cycle. Each stage in the life cycle of an apicomplexan organism is typified by a ''cellular variety'' with a distinct morphology and biochemistry. Not all apicomplexa develop all the following cellular varieties and division methods. This presentation is intended as an outline of a hypothetical generalised apicomplexan organism. Methods of asexual replication Apicomplexans (sporozoans) replicate via ways of multiple fission (also known as schizogony). These ways include , and , although the latter is sometimes referred to as schizogony, despite its general meaning. Merogony is an asexually reproductive process of apicomplexa. After infecting a host cell, a trophozoite ( see glossary below) increases in size while repeatedly replicating its nucleus and other organelles. During this process, the org ...

Centrifugal Force
In Newtonian mechanics, the centrifugal force is an inertial force (also called a "fictitious" or "pseudo" force) that appears to act on all objects when viewed in a rotating frame of reference. It is directed away from an axis which is parallel to the axis of rotation and passing through the coordinate system's origin. If the axis of rotation passes through the coordinate system's origin, the centrifugal force is directed radially outwards from that axis. The magnitude of centrifugal force ''F'' on an object of mass ''m'' at the distance ''r'' from the origin of a frame of reference rotating with angular velocity is: F = m\omega^2 r The concept of centrifugal force can be applied in rotating devices, such as centrifuges, centrifugal pumps, centrifugal governors, and centrifugal clutches, and in centrifugal railways, planetary orbits and banked curves, when they are analyzed in a rotating coordinate system. Confusingly, the term has sometimes also been used for the reactiv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parthenogenesis
Parthenogenesis (; from the Greek grc, παρθένος, translit=parthénos, lit=virgin, label=none + grc, γένεσις, translit=génesis, lit=creation, label=none) is a natural form of asexual reproduction in which growth and development of embryos occur in a gamete (egg or sperm) without combining with another gamete (e.g., egg and sperm fusing). In animals, parthenogenesis means development of an embryo from an unfertilized Gametophyte, egg cell. In plants, parthenogenesis is a component process of apomixis. In algae, parthenogenesis can mean the development of an embryo from either an individual sperm or an individual egg. Parthenogenesis occurs naturally in some plants, algae, invertebrate animal species (including nematodes, some tardigrades, water fleas, some scorpions, aphids, some mites, some bees, some Phasmatodea and parasitic wasps) and a few vertebrates (such as some fish, amphibians, reptiles and birds). This type of reproduction has been induced artificially ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
