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.

Artyom0805 [142]

Answer:

a. Mastication process and formation of bolus in the oral cavity

b. The contraction in the stomach breaks the food down into smaller pieces. These pieces are then moved to the small intestine.

c. In the small intestine, food particles are broken down into nutrients, fat, protein and carbohydrates which are absorbed into the bloodstream.

Explanation:

a. First step of digestive system functioning is the mastication process and formation of bolus in the oral cavity.

b. The contraction in stomach, with the help of digestive enzymes and acids, break the food down into smaller pieces. The small pieces of food are then released into the first part of the small intestine (duodenum).

c. In the small intestine, two enzymes released from pancreas and gall bladder break down the food particles into fats, proteins, and carbohydrates. Thereon, nutrients and carbohydrates, proteins and fats are absorbed into the bloodstream.

List four "beliefs" in which evolutionary scientists place their faith when supporting the theory of evolution. Use complete sen
VashaNatasha [74]

Answer:  Answers below.

Explanation: One aspect in which evolutionists place their faith in is the geological column. If you examine a chart of it, you will notice a trend. As you go deeper into the geological column, the fossils found there get more and more "simple". On the surface of the geological column, scientists have found more complex life forms. This trend suggests that organisms evolved over time, and the geological column represents this trend in chronological order. However, this data could be used against evolution as well. Therefore, it is inconclusive. If you believe the sedimentary rock formed so rapidly due to the biblical flood, this is evidence against evolution. If you believe rocks formed according to the observations of Charles Lyell, then this could be evidence for evolution. It all depends on how one interprets the data.

Another aspect in which evolutionists place their faith is something they call "intermediate links" Intermediate links are supposed to indicate a transitional form between two different creatures to show that they evolved. For example, evolutionists state that the creature Archaeopterynx is the transitional form between reptiles and birds. Another example of a transitional form found is the Australopithecus afarensis, which is supposed to be the transitional form between apes and humans due to similar bone structures and that this creature was bipedal like us humans.

Another belief evolutionists have to support the theory of evolution is the science of structural homology. Structural Homology is a science that studies similar structures in different organisms. For example, if you examined the forearms of a bat, bird, porpoise, and human, you would find that they have similar forearm structures, They all have a radius, humerus, ulna, carpals, metacarpals and phalanges. This indicates that all these creatures evolved from a common ancestor due to their strikingly similar structures.

Another aspect in which evolutionists place their faith is in the science of molecular biology. You see, all organisms contain a common protein called cytochrome C. Cytochrome c performs the same basic function in every organism. It is possible to calculate the percentage difference between the cytochrome c in each organism. Evolutionists have created a table that shows the percentage difference between a few different species of organisms. What they found appeared to indicate an evolutionary trend. However, more research shows that this data is highly flawed. If you calculate the percentage difference of this protein between a horse, pigeon, tuna, silkworm moth, wheat, the yeast and compared it to a bacterium ( the "simplest" life form) you would find that all these organisms are almost the same percent different from each other, indicating individual species rather than evolving from a common ancestor. All of these assumptions stated above can be evidence for or against evolution. It all is determined by how someone interprets these facts. I hope this helped you! Good luck :)

I WILL MARK BRAINLIEST + 5 STARS + A LIKE ANSWER THE QUESTION IN THE PHOTO
NNADVOKAT [17]

Answer:

1. Ribose (type of sugar found in ATP and ADP molecules)

2. The 3 phosphate groups (Energy is stored in the 3 phosphate groups and in order to bring the stored energy to use, the last phosphate bond breaks and energy is released)

3. ATP has a higher energy potential than ADP (This is cuz, ATP has 3 phosphate groups and ADP has 2 phosphate groups)

Hope this helps!
