Which of the following rows correctly identifies a difference between blastocysts and morula? Select one:

Describe each of the following early embryonic development stages of the human: a. zygote (fertilization) b. cleavage c. morula d. blastula (blastocyst) e. gastrulation (gastrula) f. organogenesis Name the three embryonic layers produced during gastrulation and the adult tissue formed from each. Note whether each of the following get bigger, smaller, or stay the same through cleavage: Mass (size of entire structure) b. size of individual cells c. number of cells a. State what the following structures will form during embryonic development: inner cell mass b. outer cell layer/trophoblast Describe the functions of the placenta during gestation and explain the relationship between fetal and maternal blood. Describe the 3 stages to labor and the effects of oxytocin and prostaglandins during these stages. Detail the effects of prolactin and oxytocin on lactation Animal Behavior Define innate and learned behavior and give an example of each. Discuss the different ways members of a population…

Which of the following is an illustration of permissive interaction? The epidermis signals the underlying dermis to create condensations and the dermal condensations then signal the epidermis to form specific cutaneous structures. Wing epidermal epithelium produces wing feather when exposed to wing dermal mesenchyme but will produce scales and claw when exposed to foot dermal mesenchyme. When implanted in the newt embryo, the frog oral ectoderm can only differentiate into frog derivatives and will not differentiate into newt derivatives. D An inducing signal from the optic vesicle is necessary for new gene expression in the lens ectoderm. E) Contact with the appropriate extracellular matrix is sufficient for cells to express differentiation-specific genes.

What is the importance of blastopore formation in protostomes? There may be multiple correct answers. Select one or more: O it is involved in the process of gastrulation to form the third layer of tissues in triploblastic organisms: the mesoderm O it is involved in the process of gastrulation, and will be used to release gases from the internal body of an organism O that the gastrovascular cavity of protostomes is formed by the indentation of the blastula early in development, starting with the mouth O that the gastrovascular cavity of protostomes is formed by the indentation of the blastula early in development, starting with the anus O the blastopore isn't really that important
