I think it's a little simpler than what you describe- phenotypic plasticity is the abstract property of phenotypes differing with respect to environment, whereas a reaction norm is a particular environmental response. So you might make an argument like this: "Daphnia show extensive phenotypic plasticity in their morphology. For example, see the attached ...


Phenotypic plasticity, as you define in your question, is an ability or a property of the organism (a given genotype) to manifest different phenotypes in different environments (Pigliucci et al., 2006). Reaction norm is an analysis of the pattern of phenotypes exhibited in different environments. In other words it is an analysis of the phenotypic plasticity....


A substrate is an underlying substance or layer, or less strictly, the medium within or upon which an organism grows. For instance, you can have a filamentous fungus grow on a solid medium (e.g. on an agar plate) or in liquid medium (e.g. in a shaken flask containing a solution) and its substrate would be the contents of the agar or solution. It's nothing ...


A tendon usually connects a muscle to a bone, but not always. According to InnerBody, the diaphragm muscle originates at the lumbar vertebra, lower ribs and sternum and inserts to the central tendon. The central tendon — a flat aponeurosis made of dense collagen fibers — acts as the tough insertion point of the muscles. So, the central tendon acts as ...


This phenomena has elements of what, in the UK, are termed Phoenix Trees, however this term, and the term Phoenix Regeneration, is more often used when describing characteristics of ancient and veteran trees. The principles that underlie what the photo shows is that new growth on trees will always grow strongest where there is the most light available, and ...


The tendon and muscle attachment are not the same. In your example, both are affected, so they are described separately. A muscle extends into a tendon and this into an enthesis - an actual attachment site where the muscle is attached to the bone (PubMed).


Myotube is A skeletal muscle fiber formed by the fusion of myoblasts during a developmental stage; a few myofibrils occur at the periphery, and the central core is occupied by nuclei and sarcoplasm so that the fiber has a tubular appearance and u have the diagrams.


A myotube is a type of cell which will develop into a muscle fiber. It is formed by the fusion of multiple myoblasts, and thereby acquires multiple cell nuclei. The nuclei are in the middle of the myotube cell, unlike the mature muscle fiber where the nuclei are at the periphery of the cell. A myotube has a tubular form instead of the more typical rounded ...
