you are interested in studying a receptor and decide to make a knockout mouse. however, you notice severe developmental defects that result in embryonic lethality in the receptor knockout mice. which developmental process is most likely affected if the receptor is on the cell surface, and the knockout disrupts its ability to receive a signal and initiate a transduction pathway?

Imagine that certain laws of physics could be ignored and you were able to travel vast distances in moments. now imagine that you traveled to an earth-like planet located light-years away that is known to support life. think about what you’ve learned in this unit and make an argument for what you think would be the dominant type of life form on this planet. consider whether a notochord is required for an organism to manipulate its environment and become a dominant creature.
