Describe events prior to and during fertilization that help lead to establishing the localized signaling pathway that creates an anterior/posterior axis of dorsal mesoderm. You can choose this in any animal that was discussed in this section. (sea urchin, fly, frog, avian, mammal, human). Choose the animal you feel most confident in describing how these events occurred.

Using the time frame of gastrulation and the model organisms bird and mice, explain 2 similarities and 1 difference regarding this process.  Remember in your difference, do not just explain one side and say “and the other one doesn’t”- explain the biology of the difference.

During gastrulation in frogs the bottle cells are the first cells to initiate the inward motion of creating the dorsal lip.  Design an experiment in which you determine if the dorsal lip cells are sufficient for gastrulation.

Another way to compare and contrast in development is to consider what is the equivalent event/structure between organisms.  For the following questions, State the equivalent event/structure between the two organisms listed. 2. Explain the reasoning that brought you to this answer   Axis formation in birds compared to humans

Developing fly larvae (egg) express Hox genes that work in a similar manner to those in mammals.  Below is a diagram of the larvae Hox gene expression and phenotype.  Choose from the drop down menus to finish the sentence correctly based on the image provided.  3pts    “A fly that has gain of function of Hox gene Antp, would create a fly that has no [option1], but has an extra set of [option2] in position [option3].”

Given the SQL Database as the following: CREATE TABLE t1 (id integer, name text); INSERT INTO t1 VALUES (generate_series(1,10000), ‘Noname’);   And the NoSQL Database in MongoDB as the following: Collection t1 {     { id: 1, name: “Noname” },     { id: 2, name: “Noname” },     { id: 3, name: “Noname” },      …      { id: 10000, name: “Noname” }, } Create the shell commands in MongoDB that are equivalent as the following SQL Command:   SELECT name FROM t1 WHERE id>1000; For example: SQL Command                                  MongoDB Shell Command SELECT * FROM t1;                          db.t1.find( ); or db.t1.find({ });
