Unlike whitewater kayaking, which requires complete focus -- a mastery of the Eskimo roll, for instance, is essential -- rafting confers the benefit of a certain degree of languor in calmer waters.
unc-18, for instance, is essential for synaptic transmission [ 13], and unc-18 mutants are almost totally paralyzed, feed slowly, and grow and reproduce much more slowly than wild type [ 14].
In such instances, it is essential that scientists and managers identify areas within watersheds where protection would produce the most substantial water quality benefits, and prioritize these areas for protection.
For instance, LOX is essential in hypoxia driven metastasis and LOX-L2 is involved in ECM remodelling in fibrosis.
If they have moved, for instance, it is essential to make sure that NSLDAS is notified.
For instance, zinc is essential for the development of immunity during childhood because of its global role in the normal development and function of cell-mediating innate immunity, neutrophils, NK cells, and macrophages.
For instance, TLR2 is essential for the recognition of lipoproteins, peptidoglycan and lipoteichoic acids of most Gram-positive bacteria (Ref. 10); TLrecognisessendotoxinxin of Gram-negative bacteria (Ref. 11); and TLR9 recognises microbial unmethylated CpG-DNA (Ref. 8).
For instance, it is essential for posterior development in arthropods (Bolognesi et al., 2008; McGregor et al., 2008; Miyawaki et al., 2004) and posterior expression of Wnt ligands is found in onychophorans and annelids (Hogvall et al., 2014; Janssen et al., 2010).
For instance, nitrate reductase is essential for ferric ion reduction to iron nanoparticles.
