Answer:

Archaebacteria

Explanation:

Archaebacteria is a group of single-celled organism present on the earth which are thought to be descended from the ancient bacteria.

These bacteria can survive the extreme or harsh conditions present on the Earth-like in the hot springs.

The archaebacteria cell membrane is made up of ether-linked phospholipids which are ester-linked in Eubacteria and eukaryotes.  The sugar present in the archaebacteria is very similar to peptidoglycan in composition but it is not peptidoglycan.

Thus, Archaebacteria is the correct answer.

Answer:

Why is it important to learn about stem cells and stem cell research?

Researchers hope stem cell studies can help to: Increase understanding of how diseases occur. By watching stem cells mature into cells in bones, heart muscle, nerves, and other organs and tissue, researchers may better understand how diseases and conditions develop.

How does stem cell research affect society?

Research with embryonic stem cells may lead to new, more effective treatments for serious human ailments and alleviate the suffering of thousands of people. Diseases such as juvenile diabetes, Parkinson's disease, heart failure and spinal cord injuries are examples.

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.
