- Explain why knowing how gene expression occurs is important in understanding developmentarrow_forwardAnswer 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?arrow_forwardDo 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:arrow_forward
- What is redeployment in developmental biology?arrow_forwardDNA sequences called homeoboxes help homeotic genes in animals direct development. Given that they are common to flies and mice, explain why these animals are so different.arrow_forwardCategorize each statement as an example of adhesion, communication, or differentiation. Statement During animal development, proliferating cells become organized into sheets of cells called epithelia. Cadherins play and essential role in maintaining the integrity of these sheets in a process known as: Complex multicellular organisms rely on signaling molecules synthesized by one cell to bind to receptors on the surface of a second cell to regulate gene expression. This type of interaction between two different cells is a form of: The human body contains 200 distinct cell types, yet each cell contains the same genome. The process by which each cell adopts a specific fate is known as: differentiation Answer Bank adhesion communication Categoryarrow_forward
