Reduction or reducing has several meanings:
In mathematics, reduction is the process of manipulating a series of equations or matrices into a desired 'simpler' format.
reduction division
the division of chromosomes previous to sexual reproduction in plants and animals in which the normal diploid, somatic number of chromosomes is reduced to the monoploid (haploid), single number; same as meiosis ...
Reduction or reducing may also refer to:
Reduction (mathematics), the process of manipulating a series of equations or matrices into a desired 'simpler' format ...
Reduction often involves free radicals as intermediates which react rapidly with oxygen to form superoxide radicals, inhibiting drug reduction.
reductional division The ?rst division in meiosis; results in each daughter cell receiving one member of each pair of chromosomes. PICTURE ...
reduction
reflex
[L. reflectere, to bend back]
An automatic reaction to a stimulus, mediated by the spinal cord or lower brain.
Reductionism
The understanding of complex systems almost always has to await unraveling the details of some simpler system.
Reduction is gain of electrons or hydrogen atoms and is associated with a gain of energy.
Oxidation and reduction occur together. When a molecule is oxidized, another must be reduced.
Reduction division The first meiotic division in which the chromosome number is reduced by half.
Reduction of the Socioeconomic Causes of Extinction
Basic social and economic issues that drive explosive population growth and increased exploitation of natural areas must be addressed. Estimate predict a doubling of the 5.
Reduction of crossing over within an inversion loop in inversion heterozygotes due to physical constraints during synapsis.
reduction division The first nuclear division of meiosis during which the paired homologues migrate to opposite poles, resulting in cells with a reduction from a diploid to a haploid number of chromosomes.
reduction - addition of electrons
ribosome - a complex of more than 50 different proteins associated with several structuralRNA molecules (rRNA's) ...
Reduction of dimensionality. For example, a 3D image (x/y/z) can be projected into the x/y plane by assigning the maximum intensity that can be found along the z axis at each x/y position to a single projection image.
Reduction has been a philosophical problem with respect to science for about 60 years.
2. Reduction in a persons capacity to fulfill a social role as a consequence of an impairment, inadequate training for the role, or other circumstances.
See: disability.
a) Reduction in redundancy would result from more efficient and rapid closure of even long gaps which are currently avoided at the price of 7- to 9-fold redundancy in shotgun. Instantly available primers would also improve the quality of sequencing.
C. reduction of oxygen to produce water
D. synthesis of glucose
E. utilization of carbon dioxide ...
The bacteria reduction on this water is just amazing. It's amazing what they can do for the metal problem because it's low maintenance, it's fairly inexpensive, we can haul manure ten miles, and that's just about it, ...
Oxidation-reduction reaction A reaction that transfers electrons.
Oxidative phosphorylation The process in which ATP is formed as a result of the transfer of electrons from NADH or FADH2 to O2 by a series of electron carriers.
[Gr. meiosis - reduction]. Two consecutive nuclear divisions whereby the resultant daughter nuclei contain half the chromosome complement of other somatic cells; occurs at time of gametogenesis. Synonym: reduction division.
Meiosis. The reduction division process by which haploid gametes and spores are formed, consisting of a single duplication of the genetic material followed by two mitotic divisions.
Both the reduction of the chromosome number from 2n to 1n and the recombination of genes is accomplished in an amazingly simple way.
"Doubling; reduction to tendinous band; insertion partially into fourth metacarpal.
The founder effect is the reduction in genetic variation that results when a small subset of a large population is used to establish a new colony.
- Primary alcohols found in plant matter which play a role in the reduction of cholesterol and in stimulating apoptosis. Monoterpenes also increase the levels of liver enzymes involved in detoxifying carcinogens.
Use this interactive animation to follow Meiosis I (reduction division) and Meiosis II in a continuous sequence or stop at any stage and review critical events.
A more realistic and accurate definition of Biology is the reductionist definition:
Biology is the natural science that studies the no-spontaneous transfer of energy and the quasi-stable systems that experience it.
Bottleneck: A drastic reduction in the population size followed by an expansion. This often results in altered gene pool as a result of subsequent genetic drift.
For this reason, meiosis is often called a "reduction division". In organisms with a diploid life cycles, the products of meiosis are usually called gametes.
Mitosis
The normal process of nuclear division in a eukaryote, whereby nuclear division occurs on a spindle structure without reduction in the chromosome number in the daughter nuclei.
TATA box: A sequence found in the promoter (part of the 5' flanking region) of many genes. Deletion of this site (the binding site of transcription factor TFIID) causes a marked reduction in transcription, ...
