What happens to carbon dioxide molecules in the body cells?​
Olin [163]

Answer:

Carbon dioxide can be transported through the blood via three methods. It is dissolved directly in the blood, bound to plasma proteins or hemoglobin, or converted into bicarbonate. The majority of carbon dioxide is transported as part of the bicarbonate system. Carbon dioxide diffuses into red blood cells.

In the future, phylogenetic studies should be conducted to ________. In the future, phylogenetic studies should be conducted to
Artist 52 [7]

Answer:

a. resolve the branching patterns (evolutionary history) of the Lophotrochozoa

b. (the same, it is repeated)

Explanation:

Nemertios (ribbon worms) and foronids (horseshoe worms) are closely related groups of lofotrocozoa. Lofotrocozoans, or simply trocozoans (= tribomastic celomados with trocophoric larva) are a group of animals that includes annelids, molluscs, endoprocts, brachiopods and other invertebrates. They represent a crucial superphylum for our understanding of the evolution of bilateral symmetry animals. However, given the inconsistency between molecular and morphological data for these groups, their origins were not entirely clear. In the work linked above, the first records of genomes of the Nemertine worm Notospermus geniculatus and the foronid Phoronis australis are presented, along with transcriptomes along the adult bodies. Our phylogenetic analyzes based on the genome place Nemertinos as the sister group of the taxon that contains Phoronidea and Brachiopoda. It is shown that lofotrocozoans share many families of genes with deuterotomes, suggesting that these two groups retain a common genetic repertoire of bilaterals that do not possess ecdisozoans (arthropods, nematodes) or platizoos (platelets, sydermats). Comparative transcriptomics demonstrates that foronid and brachiopod lofophores are similar not only morphologically, but also at the molecular level. Although the lofophore and vertebrates show very different cephalic structures, the lofophorees express the vertebrate head genes and neuronal marker genes. This finding suggests a common origin of the bilaterial pattern of the head, although different types of head will evolve independently in each lineage. In addition, we recorded innate immunity expansions of lineage-specific and toxin-related genes in both lofotrocozoa and deuterostomes. Together, this study reveals a dual nature of lofotrocozoans, in which the conserved and specific characteristics of the lineage shape their evolution.
