The damson (/ ˈ d æ m z ə n /), damson plum, or damascene [1] (Prunus domestica subsp. insititia, sometimes Prunus insititia), [2] is an edible drupaceous fruit, a subspecies of the plum tree. Varieties of insititia are found across Europe, but the name damson is derived from and most commonly applied to forms that are native to Great ...
The composite is then converted into an AP score of 1-5 using a scale for that year's exam. [5] Students generally receive their scores by mail in mid-July of the year they took the test. Scores can be viewed on the College Board website using My AP. Alternatively, they can receive their scores by phone as early as July 1 for a fee. [6]
Disease is any condition that impairs the normal physical or mental (or both) function of an organism. (Though this definition includes injuries, it will not be discussed here). Diseases can arise from infection, environmental conditions, accidents, and inherited diseases. It is not always easy to classify the source of a health problem.
In biology and botany, indeterminate growth is growth that is not terminated, in contrast to determinate growth that stops once a genetically predetermined structure has completely formed. Thus, a plant that grows and produces flowers and fruit until killed by frost or some other external factor is called indeterminate.
This is a visual depiction of what conditions would allow for an auxotroph (top row of media: Colonies Auxotrophic to Arginine) compared to colonies that exhibit prototrophy (bottom row of media). Auxotrophy ( Ancient Greek : αὐξάνω "to increase"; τροφή "nourishment") is the inability of an organism to synthesize a particular ...
In addition to growth by cell division, a plant may grow through cell elongation. This occurs when individual cells or groups of cells grow longer. Not all plant cells grow to the same length. When cells on one side of a stem grow longer and faster than cells on the other side, the stem bends to the side of the slower growing cells as a result.
Resource availability is essential for the unimpeded growth of a population. Examples of resources organisms use are food, water, shelter, sunlight, and nutrients.[1][2] Ideally, when resources in the habitat are unlimited, each species can fully realize its innate potential to grow in number, as Charles Darwin observed while developing his theory of natural selection.
The hard surface of the seed is less permeable to the penetration of harsh surface sterilizing agents, such as hypochlorite, so the acceptable conditions of sterilization used for seeds can be much more stringent than for vegetative tissues. Tissue-cultured plants are clones. If the original mother plant used to produce the first explants is ...
