Which of the following is not a statement of von Baer's laws? Less general characters develop from the more general, until finally the most specialized appear. The general features of a large group of animals appear earlier in development than do the specialized features of a smaller group. (C) All of the above are Statements of von Baer's laws. The early embryo of a higher animal is never like a lower animal, but only like its early embryo. The embryo of a given species, instead of passing through the adult stages of lower animals, departs more and more from them.

What conclusion can be drawn from embryological development? Insect and bird wings are similar in function but not in structure. Paleontologists have used fossils to trace the evolution of the modern camel. Many organisms have structures with no apparent function found during embryo development. The presence of gill slits and tails in early vertebrate embryos shows that they may share a common ancestor.
In some ways, human development is like that of a sea urchin, in others more like the of a frog, and in other ways more like that of a bird, and even more like that of a dog. Explain in a few sentences how this is true for each of these different animals.
a. What is Type I and Type II embryogenesis? When did they evolve? Compare the two and give an example an extant (living) organism that follows each one. b. Type III embryogenesis evolved later, during which era? What group of animals follow Type III? Why would this type of embryogenesis evolve?
One of the earliest experimental embryology experiments was conducted by Wilhelm Roux, who used a hot needle to kill one of the cells in an amphibian embryo at the two-cell stage. In the experiment, the remaining living cell formed only half of an embryo. However, later vertebrate experiments showed that by completely separating cells in early embryos, each can make complete individuals. What could explain the discrepancy in these experiments?
Do all of them please True/False: 24) Studies of invertebrate and vertebrate development suggest that there is a universal body plan for bilateral animal development.Answer: 25) One of the four overlapping stages in animal development is apoptosisAnswer: 26) The primary interest of genetic research into stem cells is the desire to be able to clone a human being.Answer: 27) Unipotent cells may differentiate into all other cell types of the body.Answer: 28) The reduction of pollutants in the environment by microorganisms is called biodegradation.Answer: 29) A transgenic organism has recombinant DNA integrated into its genome.Answer: 30) An organism that can be regenerated by somatic cells is called multipotent.Answer:
You are given an embryo with eight cells and you carefully separate them and allow them to develop in separate containers. Each of the cells forms a complete embryo that develops normally into an adult animal. How would you categorize your animal? It is a protostome. It has determinate cleavage. It has spiral cleavage. It is an annelid, mollusk, or arthropod. It has indeterminate cleavage.
The diagram shows various stages of embryonic development in 5 vertebrate species. Which of the following statements is supported by this diagram? salamander tortoise chicken human O Different animals go through similar stages of development during their embryonic stages. O Humans go through more stages of development than other animals. O The developmental stages of animals are very different: they have no similarities
These are embryos at their most advanced stage, shortly before birth. Fish Salamander Tortoise Chick Rabbit Human Describe how the embryos changed for each of these organisms from their earliest to latest stages. Species Anatomical Changes From Early to Late Stages Human Developed limbs, defined features in face, neck, ears, loss of tail, tiny fingers present Chicken Developed beak, tail shorter, wings and legs developed, head quite large Rabbit Tail gone, developed limbs, detailed features in ears and mouth Tortoise Shell developed, limbs have developed, tail is thinner, large belly, long tail, beak Salamander Has gills, tail and large underbelly Fish fins developed, gills, tail and scales 1. Look again at the six embryos in their earliest stages. Describe the patterns you see. What physicalsimilarities exist between each of the embryos? 2. Does this suggest an evolutionary relationship? Explain how.these embryos can be used as evidence of acommon ancestor between each of these six…
18) At a high level, animals can be placed into evolutionary groupings based on their pattern of embryonic development. One of these patterns is called deuterostome development, where the opening called the ______ becomes the ______ and the embryonic cells exhibit _______ development. Group of answer choices gastrula, mouth, indeterminate blastopore, anus, indeterminate blastopore, mouth, determinate gastrula, anus, determinate blastopore, mouth, indeterminate
Answer the following: More recently evolved organisms have modified the stages of embryological development. Would you expect early or late stages to be modified the most? Why? The basic stages of embryological development are remarkably similar for a wide range of organisms. How would you explain such consistency? As cells invaginate and move about, do they “know” where they are? If not, how is movement controlled? If so, how do they perceive their position. Is parental care of a species a factor that affects embryological development? If so, how?
What are the concepts of the following? 1, developmental anatomy 2, embryology 3,pre-embryology development
