1define magnification and resolution in the use of a microscope. 2 state why cells must be relatively small. 3 compare the structures of prokaryotic cells and eukaryotic cells. 4 identify the structures of cell membranes. 5 describe the role of the nucleus in cell activities. 6 describe the role internal membranes play in protein production. 7 describe the importance of mitochondria in eukaryotic cells. 8 match the organelles of an animal cell. 9 match the organelles of a plant cell. 10 describe the four stages of mitosis. 11 describe the stages of meiosis

1. Magnification is the degree to which the size of an image is larger than the image itself and resolution is the degree to which it is possible to distinguish between two objects that are very close together.

2. Cells must be small so movement can be achieved.

3. Prokaryotic cells don't have a nucleus or membrane bound organelles while eukaryotic does.

5. The nucleus regulates and determines/control the genetic material

7. The importance of mitochondria in eukaryotic cells is that it helps breaks down the carbs which is used for energy/ATP.

10. The first and longest stage of mitosis. In this stage the chromosomes become visible and the centrioles separate and move to opposite poles of the cell. The second stage of mitosis. In this stage the chromosomes line up across the center of the cell and become connected to the spindle fiber at their centromere. The third stage of mitosis. In this stage the sister chromatids separate into individual chromosomes and are pulled apart. The fourth and last stage of mitosis. During this stage the chromosomes gather at opposite ends of the cell and lose their distinct rod-like shapes. Two new nuclear membranes then form around each of the two regions of DNA and the spindle fibers disappear.

11. Prophase I: The chromosomes condense, and the nuclear envelope breaks down. crossing-over occurs. Metaphase I:Pairs of homologous chromosomes move to the equator of the cell.Anaphase I: Homologous chromosomes move to the opposite poles of the cell. Telophase I and Cytokinesis: Chromosomes gather at the poles of the cells. the cytoplasm divides. Prophase II A new spindle forms around the chromosomes. Metaphase II: Chromosomes line up at the equator. Anaphase II: Centromeres divides. chromatids move to the opposite poles of the cells. Telophase II and Cytokinesis :A nuclear envelope forms around each set of chromosomes. the cytoplasm divides.

explanation:

the oceanic zone is typically defined as the area of the ocean lying beyond the continental shelf, but operationally is often referred to as beginning where the water depths drop to below 100 meters (328 feet), seaward from the coast to the open ocean.
