Step by step
Solved in 2 steps
- Although most salamanders have four legs, a few species that live in shallow water lack hind limbs and have extremely tiny forelimbs (see photograph).Develop a hypothesis to explain how limbless salamanders came about according to Darwin’s mechanism of evolution by natural selection. How could you test your hypothesis?Humans as individuals have a number of disadvantages compared to other animals. For instance we are not very fast, strong, cannot see well in the dark, have a poor sense of smell and hearing compared to other animals, and we are not very good climbers. With all of these disadvantages how is it that we have been so successful? Shouldn't we have gone extinct as other humanoids such as Homo erectus? Discuss why humans have beaten the odds and are so successful.fossils from the paleozoic era have been found and it is understood that fossils of insects from that time were bigger than they are today. Why did that happen?
- QUESTION 3 Which of the following is NOTa characteristic of all chordates? O Bilateral symmetry O Hollow nerve cord O Ability to live out of water O Presence of a notochord O Presence of a muscular tailBirds have all of the following features except: they have external fertilization always have two pairs of limbs they are homoeothermic they have feathersThe ancestors of extant tetrapods first evolved the ability to live out of water over 350 million years ago. Which of the following had to have been true for natural selection to have favored the original evolution of limbs? A) Closely related lineages that remained in the ocean must have gone extinct. There must have been differences in survival and or/reproduction based on size, musculature, bones or other (B functional aspects of early limbs. Large predators must have been a major source of mortality for populations that spent more time in the water and less on land. The ability of some ancestral fish-tetrapod transitional forms to move from one body of water to another during D droughts must have led to decreased mortality. E There must have been less competition for food on land.
- A terrestrial animal species is discovered with the following larval characteristics: exoskeleton, system of tubes for gas exchange, and modified segmentation. What other feature(s) might á knowledgeable zoologist predict that the adults of this species would have? Choose all that apply an open circulatory system a brain and nervous system a two chambered heart an amnioțic eggHumans are members of the phylum chordata. As such they have a notochord. The notochord in humans; Can be found next to their spinal chord Has been lost to evolution entirely and is no longer a part of the human life cycle Becomes part of the brain stem Is an embryological feature which is mostly absorbed by the backboneThe phylum Chordata only contains vertebrate species. Question 4 options: True False Which of the following is NOT true about reptiles and birds? Question 16 options: Reptiles are cold-blooded, whereas birds are warm blooded. Both reptiles and birds live exclusively on land. Both reptiles and birds lay eggs. Both reptiles and birds breath through lungs. In addition to a spinal column, what key feature distinguishes members of Vertebrata from Chordata? Question 21 options: Quadripedal Locomotion Hardened Endoskeleton The Notochord Body Hair The two main groups of vertebrates include: Question 19 options: Non-Bird Reptiles/Birds and Mammals Mammals and Amphibians Monotremes and Marsupials Fish and Tetrapods
- Pharyngeal slits are which of the following? Question 24 options: a) Openings in the pharynx. In aquatic chordates they allow for exit of water that enters the mouth. b) Elongations of the posterior portion of the body. Use for locomotion in fish, or balance in some terrestrial vertebrates. c) Flexible, rod-shaped structures that grows from mesoderm. Gives support to an animal in embryonic development of chordates or for entire life depending on the species. d) Tissues that produces thyroid type hormones. e) Hollow tubes that develops from ectoderm. Develops into the central nervous system.What does metamorphosis meanAlthough nematode worms and arthropods do not appear related, they, in fact, are. One similarity between these two groups of organisms is/are; They both have a hydrostatic skeleton They both molt They both have a segmented body plan They both have a ventral nerve cord and nerve ganglia
