Answer:
Most likely centripetal force. Newton's first law states that an object in motion will continue to remain in motion unless acted upon by an outside force. In this case, that outside force is the centripetal force.

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.
Answer:
Explanation:
As a microbiologist there are different methods are devised for characterization of microbes.such as Macroscopic analysis and microscopy method.
With the help of microscope the needed information about the individual cell such as individual cellular characteristics can be obtained, the magnification help to provide the features such as size, shape and motility of the microbes which helps to know the specific microbes characters.
When handling an unknown environmental microbe, with help of the cell characteristics of the microbes obtained using the microscope, the identity as well as metabolic characterization can be known such as the type of environment the microbes can survive in(aerobic or anaerobic), the source of food.
No growth was observed on the control plate.
The growth on the control plate indicates that the aseptic technique devised in the model was an adequate method for the prevention of the control plate from been contaminated.
Answer:
Layer J appears to be an intrusion, or molten rock. Therefore, layer J is likely igneous rock.
