1. Identify four different layers of tissue in this microscope slide of the wall of the small intestine. Mucosa: (Innermost Layer) Epimetheus (Surface Skin Cells) Submucosa: connective layers which involve the tissue Lymphatics The following slide shows a higher magnification of one (actually two) of the layers. 2. Name the layer(s), and describe how its shape affects the surface area of the lining of the intestines. Explain the importance of surface area to volume ratio with the ideal ra...

IB Biology 1.2 Latest Update Already Passed Resolution Resolution is defined as the shortest distance between two points that can be distinquished Explain why electron microscopes have a better resolution than light microscopes because the wavelength of the electrons is thousands of times smaller than the wavelength of light. Ultrastructure all the structures of a biological specimen that are at least 0.1 nm in their smallest dimension Something that electron microscopes can se...

Pre-lab Questions 1. In this lab, you will conduct three experiments. What is the ultimate goal of those experiments in the context of this lab? What learning outcomes do you think this lab is attempting to convey with them? The goal of these experiments is to determine what organisms s are present and to also aid in visualizing as well as undertsnading their microbial structures in a more accurate percepiotion. 2. Explain the purpose of staining in the context of microbiology. Why do we u...
