Semester/session grade-point average and cumulative grade-point average are calculated to represent numerically a student's quality of performance. These averages are used to determine if a student qualifies for certain academic actions (e.g., Dean's List, academic warning/drop, entrance to and changes in college/major, and graduation) and programs (e.g., student aid and study abroad). Grades and Grade-Point Equivalents. Semester/Session Grade-Point Average.
Another example of an amphiarthrosis is the pubic symphysis of the pelvis. This is a cartilaginous joint in which the pubic regions of the right and left hip bones are strongly anchored to each other by fibrocartilage. This joint normally has very little mobility.
Breaking all of the taxonomic terms down into their meanings with regard to amphipods does tell us a lot about the animals, however. Amphipods are arthropods, and as such they possess the arthropodan features of a segmented body with jointed, segmented, appendages and an external skeleton, or integument.here are three major, and one very minor, groups of amphipods, but representatives of only one of them are likely to be commonly found in our tanks. The common type of amphipod is called a Gammaridean amphipod, and belongs to a grouping named after one of the more common fresh-water amphipodan genera, Gammarus.
