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.

Look at the albino whale people have named Migaloo. The white color is the result of mutations in the genes that code for the pr

Zolol [24]

Answer:

Yes

Explanation:

If Migaloo is albino he mostlyly lives with snow and a lot of white in his souroundings. Since he is white and everything eles is white he can blend into he souroundings to hide from anything trying to attack/eat him.

3. How does the salinity in water change as you move from inland areas out towards the ocean? Be sure to include the phrase "bra

Len [333]

Answer:

Explanation below.

Explanation:

3. The salinity of water increases as the water moves from the inland area to the ocean. This is because the ocean has high salinity.

Salinity is the amount or concentration of salt in the water.

WAYS BY WHICH ESTUARIES PROTECT THE INLAND AREAS

1. The plant in estuaries prevent shoreline erosion.

2. Protect the inland areas from flooding.

3. Protect the inland areas from storm surges from hurricane.

IMPORTANCE OF ESTUARIES TO INLAND PEOPLE AND WILDLIFE.

1. They provide nesting and feeding habits for many aquatic plants and animals.

2. Provide goals and services that are economically and ecologically indispensable.

3. Prevent shoreline erosion

4. Protect the inland areas from flooding.

IMPACTS OF DREDGING ON FISH LIVING ESTUARIES.

Dredging have negative impacts on the organisms in estuaries. These are

1. Habitat degradation

2. Remobilization of contaminants

3. Increase rate of sedimentation.

4. Increased the concentration of suspended matter.
