5. For this part of the lab you will be observing a whitefish blastula under the microscope. A blastula is a developmental stage in many animals. It occurs shortly after fertilization and the formation of the zygote. It is the “ball of cells” stage of development, where cells are dividing rapidly to form the multicellular organism. Note: In this simulation early and late prophase are combined into one stage: prophase. 1. Go to the Virtual Microscope (Links to an external...

Can anyone help me with this? Thank you.
Lab 13. Mitosis and Meiosis Purpose The purpose of this lab is to understand the process of mitosis and melosis in animal and plant cells. Learning Objectives After completing this lab, you will be able to: 1. Describe the stages of mitosis. 2. Identify the stages of mitosis in an onion root or whitefish blastula using a light microscope. 3. Describe how cytokinesis differs in plant vs. animal cells. 4. Name and...

1. Fill out the following table by indicating which general technique (light microscopy (LM) or electron microscopy (EM]) could be used to observe each structure or phenomenon. Put "no" in the box if the technique could not be used. If light microscopy can be used, name one technique (bright-field, phase-contrast, fluorescence, etc.) that you think would be effective. You will find some useful information in Appendix 1 of this manual and Chapter 18 of your textbook. Structure or phenomenon Could...
