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

6) In the cnidarians, Choanocytes, the cells responsible for filtration, are located in the ectoderm. The cnidocytes, located in the endoderm, are the cells specialized in capturing prey. Cnidocysts, located in the ectoderm, are the cells specialized in prey capture. Choanocytes, located in the ectoderm, are the cells specialized in prey capture. The cnidocytes, located in the ectoderm, are the cells specialized in prey capture.

It is a basic idea of human biology, taught in grade schools everywhere: Identical twins come from the same fertilized egg and share identical genetic profiles. But according to new research, though identical twins share very similar genes, identical they are not. The discovery opens a new understanding of why two people who hail from the same embryo can differ in phenotype (physical characteristics), as biologists refer to a person’s physical manifestation.   The new findings appear in the March issue of The American Journal of Human Genetics, in a study conducted by scientists at the University of Alabama at Birmingham and universities in Sweden and the Netherlands. The scientists examined the genes of 10 pairs of monozygotic, or identical, twins, including 9 pairs in which one twin showed signs of dementia or Parkinson’s disease and the other did not.   It has long been known that identical twins develop differences that result from the environment. And in recent years, it has also…

List down 3 differences and 3 similarities between the embryonic development of human & chicks

What does metamorphosis mean

What are the concepts of the following? 1, developmental anatomy 2, embryology 3,pre-embryology development

Development of an animal is controlled by the genes that are expressed during development. What roles have been proposed for Hox genes in the evolution and morphology of animal species?   Group of answer choices 1. Variation in the Hox genes may have spawned the formation of many new body plans. 2. All of these descriptions are correct. 3. The number and arrangement of Hox genes varies among different types of animals. 4. Increases in the number of Hox genes may have led to greater complexity in body structure.

Which of the following statements is true: O invagiantion is folding of cells that happens early in the embryonic development O balstocoel is the space in the morula o deuterostome animals will have the mouth first O protostome animals will have the mouth second enertocelous means the splitting of cells in the ectododerm layer which becomes endoderm

1. search for information and expand on the Anatomy and physiology of rabbits 2. please put some reference to find more information about rabbits

1.- What are the sciences and disciplines that help and support animal physiology? 2.- What are the sciences and disciplines in which animal physiology contributes knowledge and solves problems?

PART II. COMPARATIVE ANATOMY AND EMBRYOLOGY EVIDENCE > Using the information in the Reading file part Il and textbook reading, answer the following questions: 1. Whales possess vestigial organs in the form of pelvic girdle and hind limb bones. How would you explain this? Page 3 of 6 Evolution Lab Exercise Report (by Dr. Lapik) 2. How can you explain that, while forelimbs of bats and human arms are used for vastly different purposes, they do have similar anatomy? 3. How would you explain the presence of gill slits in embryos of animals that do not form gills?

The nervous system is derived from     ectoderm     endoderm     mesoderm     All of the above: it depends on whether the animal is a protostome or a deuterostome      QUESTION 7 Planarians lack dedicated respiratory and circulatory systems because     none of their cells are far removed from the gastrovascular cavity or from the external environment.     they lack mesoderm as embryos and therefore lack the adult tissues derived from mesoderm.     their flame bulbs can carry out respiratory and circulatory functions.     their pseudocoelom carries out these functions.     QUESTION 8 Animals with bilateral symmetry     can be divided into similar halves by any plane through the longitudinal axis.     are usually very slow-moving organisms.     are relatively simple in structure.     are better adapted for forward movement than radially symmetrical organisms. Help with these…

PART III: HALL OF PRIMATES 1. Leave the Hall of Advanced Mammals and head down the stairs one flight to Floor 3. Enter the Hall of Primates. Proceed into the room a short distance and hang a left to find the family Hominidae. a. When in development are humans and chimpanzees most similar? 2. Proceed through the Hall of Primates at your own pace. There are no other questions to answer in this hall. Take the stairs before the Hall of Eastern Woodland Indians down to the first floor. You should arrive right at the entrance to the Hall of Human Origins. PART IV: HALL OF HUMAN ORIGINS 1. Enter the Spitzer Hall of Human Origins. Begin by walking to the left, to the display DNA Comparing Humans and Chimps. a. What are the three primate species that descended from a common ancestor? b. How long ago did this happen? c. Which two X chromosome banding patterns were most similar between the three chromosomes shown? and 2. Continue to the left along the wall, around the corner to Evolution and How…

1. Which is not a characteristic of life? * O They are composed of one or more cells. O They respond to stimuli. O They respire/breathe. O They live. 2. What are 2 forms of reproduction? asexual & trisexual asexual & sexual sexual & sexual None of the above

2. What are the roles of the egg in animal development?  3. What about in plants, what is the counterpart of egg in plants? Why?  4. Compare between again and reptilian eggs.

2. Tissue types combine to form organs and organ systems. In the table below, explain the function of the organ in the organ systems found in animals. Organ system Digestive Organ in this system Function Nervous Respiratory Circulatory

If a deuterostome embryo split apart and one of the cells broke away early in it's development, then; The embryo would die, however the cell that broke away could survive and grow into a new individual The embryo would cease development and die Both the embryo and the cell that broke away could develop into separate animals
