Guide 3 Development Objectives
This guide’s quiz has four questions; one matching each objective.
Chromosomes & DNA
Explain what a chromosome is, where it is located in a cell, and how it is structured; model the structure of the DNA macromolecule; and describe how the structure of DNA relates to cellular function.
Life Cycles
Compare and contrast mitosis and meiosis, including the role of DNA replication, where these processes occur in an organism, and why the processes are significant; outline the life cycles of various species, indicating when mitosis and meiosis occur; and provide the characteristics of amphibians, including physical traits, life cycles, representative species, and typical habitats.
Genes & Development
Outline the steps that occur after fertilization, including how DNA directs development and factors that can impact this process; provide characteristics of reptilian species, including their evolutionary origins, shared structures, and modern descendants; and diagram the general structure of eggs, explaining their evolutionary significance and relationship to humans.
Pedigrees
Describe the basic tenants of animal care, including addressing limited resources and continual threats; provide examples of parental care in animals, including minimal intervention to long-term support; diagram the pedigrees for various animal crosses, including genotypes and phenotypes of parents and offspring.
