Vertebrate

The Book of Life Worksheet Please submit your assignment as a .pdf file. This ensures that it is readable on every computer. Please also put your last name in your save file (i.e. ChewBookofLife.pdf) 1. What organisms are believed to be the oldest organisms on Earth? Archaea (oldest!) and Bacteria. 2. What do you think are the implications of studying these organisms in comparison to human DNA? What knowledge might we gain about ourselves from them? There are many genes that are similar…

In higher vertebrates, such as amphibians and mammals, two blood coagulation pathways exist which both trigger the activation of thrombin through enzymatic cascades: an extrinsic tissue factor pathway, initiated mainly by internal or external trauma, and an intrinsic contact activation pathway, which is employed to repair minor external damage and injures. The binding of tissue factor (TF) to activated factor VII (FVIIa) is essential in the commencement of the coagulation cascade, as it serves…

flowering plants which share the same basic anatomies; however, they can look very different as a result of selection in different physical environments and adaptation to different kinds of pollinators,” (Avissar et al., 2013, p.486). In addition, the vertebrate forelimbs, which formed paddling in whales, hands in primates, as well as bats wings. Convergent Evolution Convergent evolution is opposite of divergent evolution. From different…

(2014) analyzes the new and different discoveries that support fish cognition. One of those discoveries is that vertebrates share a network in their brains that assist in social decision-making, which in turn may suggest a similar structure in our common ancestor that we either evolved from or is a result of convergent evolution. Social and physical environments may…

1. Discuss three types of barriers to vertebrate distribution and give an example of each. (1) Physicalbarriers: This one of the barriers that the vertebrates usually encounter during their life. Land is one of the main factors that contributes to physical barrier since some of the species are constrained in specified geographic factor and also some physical conditions. Water is also another constrain i.e. for other species get constrained. The type of topography and also the soil type is of…

connection of every lands. Although the distance between some of them is quite far, similar fossils still can be found in these place. In different environments, these similar species evolved into different kind of creature. Second, the forelimbs of Vertebrates support Evolution. For example, human, cats, whales and crocodile have pentadactyl limbs, and their forms are almost the same. But their functions are very dissimilar because the species have to improve pentadactyl limbs in order to adapt…

Introduction A vertebrate is characterized by the vertebral column as it is part of their axial skeleton. Its main function is to act as a communication pathway between the brain and the body of the vertebrate. Usually, vertebrates have a fixed number of vertebral column, but there are variations in the number of vertebral columns within the cetacean species. Dolphins are vertebrates and are one of the fastest swimming species due to their morphological stability. The morphology can determine…

1 - Creature Feature” 1. Save this document in your files as “Creature Feature Your Name”. You can then complete the assignment in this document, add photos and bibliography information, and use this document as your submission. 2. Choose one vertebrate and one invertebrate that interest you. 3. Read the research project expectations carefully. There are 8 parts to this assignment – be sure to complete all 8 parts for both animals! 4. Decide where you will look for the information and whether…

Classification – Chondrichthyes is a class that contains the cartilaginous fishes: they are jawed vertebrates with paired fins, paired nares, scales, a heart with its chambers in series, and skeletons made of cartilage rather than bone. The kingdom of a grey nurse shark is Animalia because the grey nurse shark is a multicellular animal. The phylum is Chordata because it is a large animal that includes vertebrates . The class is Chondrichthyes because it has a cartilaginous skeleton. The order…

Around 543 million years ago the Cambrian Explosion occurred, some say it may represent the most important evolutionary event in the history of life on Earth. The “Cambrian Explosion” refers to the rapid appearance of most major living animal body plans in the fossil record within 20 million years or less. This may seem to be a long period of time but is a relatively short in evolutionary history. This swift change in the fossil record appears to be inconsistent with the ideal of the slow…
