To discuss:
Distinctions between keratinized and non-keratinized stratified squamous epithelia on the basis of histology, location, and function.
Introduction:
Epithelial cells are a sheet of adhering cells that cover the body surfaces and cavities in the form of internal and external linings of body organs and tissues of glands. The main functions of the epithelial cells are protection, secretion, absorption, excretion, sensation, and filtration.
Stratified epithelial cells consist of 2 to 20 layers of epithelial lining, which appears in simple, cuboidal, and columnar in shape. It acts as a protective layer since it has more number of layers. It has capabilities to withstand epithelial abrasions. It undergoes self-renewing process, where the epithelial cells constantly fill the cavities of organs.

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?

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_forward
