Can someone pleae help with 3 question for my biology homework thank you
1)List two traits that animals share with other organisms, and three traits that are unique to animals.
2)Explain the difference between protostome development and deuterostome development. Use full sentences.
3)As discussed in class, animals are classified into different phyla based on the presence of tissues. Define the two options for animals with true tissues, and give a specific animal phylum as an example of each option.

- part i Animal phylogenies based on molecular and morphological characters can be different in regards to the placement of the phylum Platyhelminthes. What is the best explanation for this?choose 1 a. The Platyhelminthes clade separated from other clades before coeloms evolved and consequently Platyhelminthes have never had a coelom. b. Some Platyhelminthes have a coelom, but others do not and it is difficult to conclude anything about its evolution within the clade. c. Platyhelminthes originated from ancestors with a coelom and have retained it to the present time. d. Modern Platyhelminthes do not have a coelom but did originate from an ancestor that had one. e. Platyhelminthes evolved from an ancestor without a coelom but developed one during the course of their evolution. part ii If current molecular phylogenies of land plants are correct and to be believed they suggest that. Choose 1 a. the Zygnematales and land plants adapted to the same environmental…arrow_forwardIt is believed that the coelacanths and lungfish represent a crucial link between other fishes and tetrapods. What is the major feature in these fish in support of this hypothesis? O Like amphibians, they are tied to the water for reproduction. Their fins have skeletal and muscular structures similar to amphibian limbs. They have lungs and are able to breathe air when water is scarce. O They have highly evolved nervous and circulatory systems. They enter a hibernative stage when food is scarce, as many tetrapods do.arrow_forwardDiscuss the idea that every evolutionary adaptation has both advantages and disadvantages, using each of the following as an example: (a) cephalization,(b) the arthropod exoskeleton, and (c) segmentation with specialization.arrow_forward
- MAKE CONNECTIONS Historically, annelids and arthropods were viewed as closely related because both havebody segmentation. Yet DNA sequence data indicatethat annelids belong to one clade (Lophotrochozoa) andarthropods to another (Ecdysozoa). Could traditionaland molecular hypotheses be tested by studyingthe Hox genes that control body segmentation (seeConcept 21.6)? Explain.arrow_forwardWhich of the following statements is true? --Sea stars are dioecious possess dermal branchiae and they have two stomachs --Actinoptergians are fleshy/lobe finned with cycloid scales and a swim bladder --Ophiuroidea have bilateral larvae, and Aristotle's lantern and five arms --Sand dollars are echinoderms with long spines, gills, and pentaradial larvae --Sharks have an operculum, cosmoid scales and eyelidsarrow_forward1.

The fossil record provides a sweeping overview of the history of life over geologic record 2.
