widest below the middle and tapering at both ends) the leaf blade is ovate (widest below the middle and broadly tapering at both ends) Leaf blade surface colors the upper side of the leaf blade is relatively uniform in color Leaf duration the leaves drop off in winter (or they whither but persist on the plant) Leaf form the leaves are green, with an expanded blade and a leaf-like texture Leaf spines there are no spines on the leaf edges Leaf teeth and lobes the edge of the leaf blade is entire (has no teeth or lobes) Leaf type the leaves are simple (i.e., lobed or unlobed but not separated into leaflets) Leaf types There is a gradual change in appearance of the leaves from the base (or near the base) of the plant to those from further up on the stem, with leaves progressively changing as one moves higher on the stem (often becoming shorter, or less toothed/lobed, and/or with shorter petioles)
Students can also use the image shown at the top of the lesson page as evidence to further explore the self-fashioning of a particular socio-cultural identity through the smoking of tobacco
Lets move on
Next-generation (modular) e-cigarettes are projected to be the fastest-growing segment, due to rising demand for customizable and high-performance vaping experiences
Moderate to Advanced Vaping Gum Disease When vaping gum disease reaches moderate or advanced stages, deeper gum pockets and bone loss are present
Neutrophils and macrophages also release reactive oxygen species, pro-inflammatory cytokines, growth factors and MMPs, which propagate chronic inflammation, emphysema, and airway remodelling processes, such as EMT, fibroblast activation and airway smooth muscle proliferation ( Figure 3 )
