1. Adjuvant
* In pharmacology, a substance that, when added to a medicine, speeds or improves its action. * In immunology, a substance that is added to a vaccine to improve the immune response so that less vaccine is needed to produce more antibodies. Such adjuvants apparently work by speeding the division of lymphocytes and by keeping the antigen in the area where the immune response is taking place. In research with humans, aluminum phosphate and aluminum hydroxide gel are commonly used; in research involving lab animals, Freund's adjuvant is used.

2. Aliquot
The division of a sample of a substance into equal parts, each of which representing a known quantitative relationship to each other and to the sample as a whole.

3. Ameiosis
A form of nuclear division which does not reduce the number of chromosome s because both of the nuclear divisions normally part of the process of meiosis have failed to occur.

4. Anaphase I
The stage in the first meiotic division of meiosis that follows metaphase I . The pairs of homologous chromosome s are separated from each other and moved to opposite ends of the cell . This stage begins as soon as homologous chromosomes begin separating and ends when the chromosome s arrive at opposite ends of the cell.

5. Anaphase II
The stage in the second meiotic division of meiosis that follows metaphase II . In each cell produced during the first meiotic division , the paired chromatid s are separated from each other and moved to opposite ends of the cell. The stage begins as soon as the centromere s connecting each chromatid to its pair break and ends when the two new sets of chromosome s arrive at opposite ends of each cell.

6. Angiospermae
A major division of the plant kingdom, commonly called flowering plants as their reproductive organs are in flowers, having seeds which develop in a closed ovary made of carpel s, a very reduced gametophyte , and endosperm develop from a triple fusion nucleus.

7. Anisogamy
A condition where the gamete s of a species have different sizes. In general, the smaller, more mobile gamete is "male" and the larger one which is packed with food and other things to give the potential zygote a good start (and is less mobile as a result) is the "female." The principle behind anisogamy is a division of the labor necessary for two gametes to unite and successfully develop.

8. Ascomycetes
division of fungi that contains the yeasts and morels; ascomycetes produce an ascus (or sac) in which ascospores are produced.

9. Ascomycotina (cup fungi, sac fungi)
A subdivision of true fungi commonly known as cup or sac fungi. They reproduce asexually through externally-produced spores called conidia and sexually with the aid of specialized sacs called asci. This division includes yeasts, morels, truffles, powdery mildews, ergot and fungi responsible for other plant diseases such as chestnut blight, peach leaf curl and Dutch elm disease.

10. Bacteria (sing. bacterium)
Tiny, unicellular, prokaryotic organisms that reproduce by cell division and usually have cell walls; can be shaped like spheres, rods or spirals and can be found in virtually any enviroment.
