Investigators of Holocene (11,700 years ago to the present) forms use other anatomic features, such as adductor muscle arrangement, the ctenidia and their junction with the labial palps, the extent and complexity of mantle fusion, stomach structure, and morphology of the hinge area to classify bivalves.
The joints within individual animals display diverse morphologies (ball-and-socket, hinge, plane, etc).
The hinge motion in hDHFR is likely mediated by hinge loops longer than those present in ecDHFR: in hDHFR, hinge 1 is defined as residues Thr39 Leu49 and hinge 2 as His127 Leu131, compared to Thr36 Pro39 and Pro105 Gln108 in ecDHFR, respectively.
Exhale and hinge into standing forward bend.
Because features such as hinge morphology, dentition, mineralogy, shell morphology and shell composition change slowly over time, these characteristics can be used to define major taxonomic groups.
Underlying them, Eagleman explains, are changes in brain morphology and chemistry.
I explained the basic principles of Arabic morphology and classical poetics to Henry, which he internalized effortlessly.
Sperm morphology and environment are also important factors, according to a couple of physicians we asked about the product.
In earlier taxonomic systems, experts used a single characteristic feature for their classifications, choosing among shell morphology, hinge type or gill type.
Forces are directed through reinforced door pillars and hinges.
