Prepare your answer in complete sentences in your own words.Exercise #6 – Page 2 of 3Sea Urchin (Red Sea Urchin)In the search field of http://marinebio.org/search enter the term Red Sea Urchin. Coccolithoviruses infect the marine microalga, Emiliania huxleyi. R.W. Are Red Sea Urchins considered plankton nekton orbenthos?12. In the case of the chloroviruses, resistance to virus infection occurs quite frequently and most of the time this is due to a change in the host receptor such that the chloroviruses are unable to attach to the host. Recent work suggests that syringolipid signalling might play a role in controlling host cell death during infection (Han et al., 2006; Monier et al., 2009; Pagarete, Allen, Wilson, Kimmance, & de Vargas, 2009; reviewed in Michaelson, 2010; Bidle & Vardi, 2011). Here are a fewdetails on the quiz: You will have 60 minutes to complete the quiz from the time you open it. MarineBio.org is a marine conservation and science education organization with a mission to educate readers about marine life and the marine environment. The group includes the coccolithophorids, which build external coverings of calcium carbonate scales (coccoliths) and tend to dominate open oceanic waters worldwide. (2004), and Short and Suttle (2002). This chromosome, which carries many predicted glycosyltransferase genes, is variable in its genetic structure in different wild-type algal strains, and appears to be involved in viral defense. Are Pacific white-sided dolphins considered plankton, nekton, or benthos? 6.3.1 Emiliania huxleyi (Haptophyta, Coccolithophyceae, Isochrysidales). The most conspicuous, well-known haptophytes, are coccolithophorids that are covered in calcium carbonate “coccoliths,” which are the source of ancient deposits of calcareous earth. Scale bars: A, B: 1 μm; C, D: 500 nm. Several other features also set this virus apart from the other phycodnaviruses. They also include one of the best-studied eukaryotic model organisms, Emiliania huxleyi, used in the study of biomineralization. This superimposed state of being both infected and resistant is reminiscent of Schrödinger’s cat; i.e., of being simultaneously both dead and alive. Do some research online and answer the followingquestions about Emiliania huxleyi. ELENA LITCHMAN, in Evolution of Primary Producers in the Sea, 2007. Coccolithophores are particularly noted for their ability to form massive blooms and for their use in geological dating. These viruses constitute a genetically diverse, but morphologically homogenous group of icosahedral viruses with large dsDNA genomes of approximately 100–560 kb. Connie Lovejoy, in Reference Module in Earth Systems and Environmental Sciences, 2019. This means that these viruses belong to families other than the Phycodnaviridae. Recent results have shown that diversity within the algal viruses is higher thanpreviously believed, including viruses with single-stranded DNA (ssDNA) and both single-stranded RNA (ssRNA) and dsRNA (double-stranded RNA) genomes. Jordan, in Encyclopedia of Microbiology (Third Edition), 2009. viewed from the inside of the coccolith layer around the cell. The structure of these coccoliths can be seen in Fig. See Section 12.4 ofyour text for help with this but make sure your answer is specific to Red Sea Urchins.
