The metabolic explanation of these processes is expressed in concepts like endogenous respiration (Gujer et al., 1999), death-regeneration (Dold et al., 1980), maintenance (Loosdrecht van and Henze, 1999) or predation (Moussa et al., 2005).xperimental evidence for the validity of the endogenous respiration model comes from Marais and Ekama (1976) . Using the OUR method, the value of b OHO was found to be 0.24 d â1 and independent from SRT in the range of 2.5â30 days. Similar results were obtained by van Haandel et al.
Whale barnacles attach themselves to the bodies of baleen whales during the barnacles free-swimming larval stage. Though often described as parasites, the relationship is an example of obligate commensalism, as the barnacles neither harm, nor benefit, their host. Elyse Â· 5 months ago. Thumbs up.
The bristles allow barnacles acting as males to detect the chemical signals given out by barnacles acting as females. Once the male barnacle sniffs out a receptive partner, it uses its long, stretchy penis to reach out and mate with her.
