Chapter 20.2, Problem 1LO
Summary Introduction
To explain: One or more key innovations or adaptations in land plants that were found most essential for their survival in the terrestrial environment and to justify them.
Introduction: The land plants first appeared between 500 and 450 million years ago in the terrestrial environment. Evolution among plants facilitated their survival on land, and it includes numerous adaptions such as the cuticles, protected embryo, gametangia, thick spore walls, stomata, mutualistic association, and protective pigments.

- Question #4: Assume you are able to use CRISPR to create an allele that will convert a cross-pollinated, sexually reproducing crop plant into an obligate apomict. Your edited obligate apomict plants retains all the CRISPR "machinery" necessary to convert the "sexually reproducing" allele to the "obligate apomict" allele. You plant 100 hectares of your edited obligate apomicts in order to increase seed for sale the following year. Neighboring farms and seed producers are growing many different un-edited sexually reproducing varieties of the crop. If your neighbors plant seed harvested from their crops that was pollinated by your crop, should they expect these seeds to generate apomictic or non-apomictic plants?

- "One of the symmetry breaking events in mouse gastrulation requires the amplification of Nodal on the side of the embryo opposite to the Anterior Visceral Endoderm (AVE). Describe one way by which Nodal gets amplified in this region." My understanding of this is that there are a few ways nodal is amplified though I'm not sure if this is specifically occurs on the opposite side of the AVE. 1. pronodal cleaved by protease -> active nodal 2. Nodal -> BMP4 -> Wnt-> nodal 3. Nodal-> Nodal, Fox1 binding site 4. BMP4 on outside-> nodal Are all of these occuring opposite to AVE?arrow_forwardIf four babies are born on a given day What is the chance all four will be girls?
